July 24 (UPI) — Measles cases have hit a record high in the United States since the virus was declared eliminated in 2000, the Centers for Disease Control and Prevention said.

The CDC said there have been 2,318 confirmed cases of measles so far this year, which beats last year’s record-breaking number of 2,289. Last year, two unvaccinated children died of the disease. More measles cases have been reported in the United States in the past two years than in all the years from 2000 through 2024 combined, The New York Times reported.

In November, a panel of experts will meet to decide if the United States has lost its status as a country that has “eliminated” the disease.

“This is just going to keep happening,” Jennifer Nuzzo, director of the Pandemic Center at the Brown University School of Public Health, told The Times. “It’s going to mean living in a perpetual state of vulnerability and risk until we get vaccination levels up.”

Last year, the largest outbreak was in South Carolina, and many of this year’s cases stem from that event. It was declared to have ended in April. Now, there’s an outbreak that started last summer along the Utah-Arizona state line and has spread throughout the Beehive State. More than 100 cases have also been reported in Lancaster County, Pa., this year.

The CDC reported 35 new measles outbreaks this year.

Measles is especially good at finding pockets of people with weak immunity.

“It’s going to find people who aren’t immune,” Dr. David Kimberlin, a pediatric infectious disease expert at the University of Alabama at Birmingham, told The Times. “It’s like a heat-seeking missile.”

Funding cuts to public health are also a concern.

Dr. Farrell Tobolowsky, medical director the San Francisco Department of Public Health’s communicable disease program, said two cases this year meant activating several contract tracing investigators.

“I don’t think our department can currently handle more than one (case) without calling in additional staff,” Tobolowsky said at a briefing hosted by the Big Cities Health Coalition, CNN reported.

“It is something that we’re concerned about all the time and is on our minds all day, every day,” she said. “Not only if there’s another measles case, but if anything else comes that is of high consequence at the same time, it will be difficult to manage two things at once.”

Courtney Spencer, a spokesperson for the Department of Health and Human Services, said the department has mounted an “aggressive outbreak response,” and said it’s given $8.5 million to states to help contain outbreaks.

She added that the department has said, “[The measles, mumps and rubella] vaccination remains the best protection against measles.”

But other professionals blame the federal government for at least part of the spread.

“We have seen virtually no national messaging. We’ve seen no ad campaigns,” Dr. Jonathan Temte, a former chair of the CDC vaccine advisory committee, said of HHS. “I think that really tells us something about their priorities.”

Dr. Andrew Racine, president of the American Academy of Pediatrics, called it a failure: “This essentially is a public health failure, and it’s avoidable.”

July 23 (UPI) — A Senate committee delayed a vote on the Trump administration’s Centers for Disease Control and Prevention director nominee, Erica Schwartz, because enough members were not present.

Sen. Lisa Murkowski, R-Alaska, was absent from the Senate Committee on Health, Education, Labor and Pensions meeting on Thursday because of a family emergency, which led committee chair Bill Cassidy, R-La., to postpone the vote, Politico reported.

Cassidy also said Thursday that he decided to vote for Schwartz because of a “good faith action” the CDC reportedly made to its website earlier in the day.

The action included changing language on its website about the lack of an association between vaccines and autism, which had been ordered changed by Health and Human Services Secretary Robert F. Kennedy Jr. last year.

Cassidy asked detailed questions during her nomination hearing about vaccines and how the agency, which has had a full-time director for just one month since President Donald Trump re-entered the White House, would restore confidence in its public health mission, The Hill reported.

“I’m confident that she knows what she’s doing and will stand against those who do not,” Cassidy said during the meeting.

“If confirmed, I look forward to working with Dr. Schwartz to protect children’s health and regain trust in the CDC,” he said.

“There’s more to do to repair the damage that has been done to the U.S. public health response, but this is a start,” the Louisiana Republican added.

Even with Cassidy deciding to vote for Schwartz, Republicans on the committee would have needed a Democrat or Sen. Bernie Sanders, I-Vt., who caucuses with the Democrats, to vote in favor.

Sanders ended that possibility when he expressed respect for Schwartz’s career but said that he was concerned she would not be able to hold off some of the controversial changes Kennedy has either proposed or forced on the agency.

“I will be voting against Dr. Schwartz because we need people in this country who are going to stand up, protect the American people and I don’t think you can see that right now with Secretary Kennedy in his position,” Sanders said.

The HELP committee’s next executive session is scheduled for July 30, which is also the next time it will consider nominations, making it the next opportunity for Schwartz’s nomination to come up for a vote.

The committee also put off a vote on Sean Kaufman, who is nominated to lead the Administration for Strategic Preparedness and Response, because Republicans did not have enough votes to forward the nomination to the full Senate.

The Trump administration’s latest nominee to lead the nation’ top public health agency drew frustrated reactions from some U.S. senators on Wednesday when they pressed her on whether she would protect the Centers for Disease Control and Prevention from political meddling.

Dr. Erica Schwartz told the Senate health committee she “will never betray the science” and pledged to use “radical transparency” in a bid to rebuild public trust in the agency. But several senators questioned how she might handle pressure from Health Secretary Robert F. Kennedy Jr., who has repeatedly moved to alter U.S. vaccine and CDC policies. Schwartz repeatedly declined to dissent from some of those actions.

Schwartz, 54, is up for director of the Atlanta-based CDC, which is charged with protecting Americans from preventable health threats.

Her career has largely been spent in military uniform, including in a leadership position at the U.S. Coast Guard where she oversaw the organization’s system of 41 clinics and 150 sick bays — as well as policies promoting vaccinations of service members. She later served as deputy surgeon general, where she helped lead uniformed medical and health professionals posted at the CDC and government health agencies that serve the general public.

The CDC long enjoyed a sterling international reputation but has been in turmoil since Trump returned to office last year. Largely due to layoffs and resignations, the agency has lost more than 3,000 employees, or more than a quarter of its workforce. Morale has plummeted as a succession of mostly temporary leaders have come and gone — the front office filled with political appointees, many of them with little or no training in medicine or public health.

“There’s still really good people who work there (at the CDC). They are doing their best to navigate choppy waters,” said Dr. David Margolius, director of Cleveland’s health department and a leader in a U.S. coalition of big city health departments. But CDC no longer seems to the authoritative and communicative lead that it was on outbreaks and other public health emergencies.

“Basically everybody’s got to kind of choose their own adventure, as opposed to being led by a national public health department,” Margolius said.

CDC has had several leaders

The agency is overseen by Kennedy, who was a leading voice in the anti-vaccine movement before he was tapped to lead the CDC and other federal health agencies. Kennedy had promised not to change the nation’s vaccination schedule. But shortly after taking office, Kennedy said he was going to investigate the childhood vaccine schedule and went on to attempt a substantial rewrite of vaccine recommendations for kids. Some of those efforts were put on hold earlier this year by a federal judge.

The administration’s first pick to run the CDC was former Florida congressman Dr. David Weldon, but his March 2025 Senate confirmation hearing was canceled an hour before it was to begin. Weldon said at the time that he’d been told not enough senators were willing to vote for him.

The White House then moved on to Susan Monarez, who had been serving as the CDC’s acting director. Monarez was confirmed by the Senate, but she was ousted in less than a month. Trump administration officials said she wasn’t aligned with their agenda so they terminated her.

Several key CDC scientific leaders resigned in protest, saying Monarez’s dismissal dashed their hopes that a CDC director would be able to guard against political meddling in the agency’s scientific research and health recommendations.

Since then, there’s been a revolving door in agency leadership, with the short-term role of acting director being passed from one Washington-based HHS official to another. National Institutes of Health Director Jay Bhattacharya has been overseeing the CDC most recently.

Schwartz said she was unaware of actions that hurt the CDC

On Wednesday, some senators suggested Schwartz should follow Monarez’s example, and they asked her about actions Kennedy has taken that have affected CDC.

Schwartz said she was unaware that CDC programs that worked to prevent smoking and promote vaccinations had been curtailed. She declined to commit to taking down a CDC website that suggests there’s a link between childhood vaccines and autism (she said she had not seen it), though she agreed existing medical evidence has not found a link.

Sen. Maggie Hassan, a New Hampshire Democrat, asked if she would — if Kennedy ordered her — suspend promotion of a flu vaccination campaign during a deadly flu season.

“Senator, I don’t speak in hypotheticals,” Schwartz responded.

“It isn’t hypothetical. It happened,” said Hassan, referring to internal CDC emails, released by Sen. Bernie Sanders last month, that documented such a directive from Kennedy to CDC staff last year.

Schwartz said she agreed that CDC should prioritize responding to infectious diseases. “I think over time, the CDC has had some mission creep, and it’s trying to be all things to all people,” she said.

But she also agreed to requests from Republican senators to — if confirmed — look into whether AI data centers cause health problems and into the possibility of establishing a World Trade Center Health Program clinical center in Florida.

Senators also heard from nominee overseeing health emergency preparedness

In April, Trump nominated Schwartz, calling her “incredibly talented.” In a congressional hearing in April, Kennedy said he approved of the choice, but refused to commit to supporting whatever vaccine guidance she might issue.

Last month, Schwartz filed letters with the government that address her finances and potential conflicts of interest. She wrote that if confirmed, she will leave her current job with UnitedHealth Group, where she’s making about $850,000 in salary and bonus money and cash out her stock options. She also will resign from the board of directors of Butterfly Network Inc., a Massachusetts company that makes ultrasound devices; from the board of Atlanta-based Aveanna Healthcare, a medical home care provider; and from the board of the Florida-based Searching for Solutions Institute.

At Wednesday’s hearing, senators also considered the nomination of Sean Kaufman as the Assistant Secretary for Preparedness and Response, or ASPR. That job entails overseeing preparations and response to public health emergencies and disasters.

Last year, the Trump administration announced a plan to bring those responsibilities under CDC, but the dramatic HHS restructuring has not happened.

The assistant secretary’s office is involved in decisions about funding next-generation vaccines against pandemic flu or other infectious disease threats. In postings on LinkedIn, Kaufman has made comments cheered by vaccine skeptics, arguing against hepatitis B vaccinations for newborns and saying he served as an expert witness to advocate for people who refused the COVID-19 vaccine.

On Wednesday, Kaufman faced questions about past social media posts, including one in which he expressed hatred for the CDC. He also repeatedly was asked about his support of a Trump administration decision last year to cancel 22 projects, totaling $500 million, to develop vaccines using mRNA technology.

Infectious disease experts say the mRNA technology used in vaccines is safe, and they credit its development during the first Trump administration with slowing the 2020 coronavirus pandemic. Future pandemics, they warned, will be harder to stop without the help of mRNA.

Kaufman said he supported mRNA technology and believes COVID-19 vaccines are safe and effective, but said it made sense to study work that’s been done so far before, including learning more about any side effects.

Sen. John Hickenlooper, a Colorado Democrat, said such evaluations are the responsibility of other federal offices — not ASPR. He also said it may slow the nation’s ability to respond to emerging new infectious threats.

July 15 (UPI) — The U.S. Centers for Disease Control and Prevention has confirmed the multistate outbreak of cyclosporiasis, the parasite-based illness, in at least four states.

The four states are Michigan, which has seen the highest rate of illness; Ohio; Kentucky; and West Virginia. But cases have been identified in 34 states, the CDC said.

The CDC had said that there was “no evidence of a single, multistate” outbreak, The Hill reported, but on Tuesday said that the hundreds of cases in the region appeared to link to a common source. The source hasn’t been confirmed, said Dr. Gwen Biggerstaff, deputy director of the CDC’s Foodbourne, Waterbourne and Environmental Diseases division. Biggerstaff hosted a call with reporters on Tuesday.

Michigan health officials have reported more than 3,700 cases of the illness and believe lettuce or salad greens could be the culprit. Dr. Donald Prater, FDA acting deputy commissioner for food, said the agency is continuing to investigate “multiple produce items, including lettuce.”

As of Wednesday, the CDC has gotten reports of at least 1,645 lab-confirmed cases of domestically acquired cyclospora since May 1, which is the start of the typical cyclosporiasis season. Biggerstaff said the agency is aware of more than 5,100 additional reports that require further analysis.

Cyclosporiasis is an intestinal illness caused by a microscopic parasite called cyclospora. It’s spread when people consume food or water contaminated with the parasite, typically fresh produce that has not been adequately washed or cooked, Biggerstaff said.

Symptoms include watery diarrhea — sometimes frequent — along with cramping, nausea, loss of appetite, fatigue and low-grade fever. Symptoms generally begin about one to two weeks after exposure, she said.

“I want to underscore an important point: This illness does not spread directly from person to person. The source of this outbreak is what we eat or drink — not casual contact with someone who’s sick,” Biggerstaff said on the call.

Biggerstaff emphasized that “the true number of infections is almost certainly higher than what’s reflected in these numbers, because many people with mild illness recover without seeking medical care and are never tested.”

Cyclospora can only be diagnosed by stool sample, the CDC said. The agency urged medical professionals to “specifically request cyclospora laboratory testing on stool specimens” to be sure of the diagnosis.

In the past, cyclosporiasis was associated with travel abroad, but in the past few years has been tied to domestic and imported produce.

The CDC said the reason cyclosporiasis investigations take longer is because people show symptoms up to two weeks after exposure to the parasite. Also, there is no whole genome sequencing of the parasite, which makes it more difficult to match the food product to the people made sick by it.

Instead, labs use genotyping, which is not as fast or precise, Biggerstaff said. In some cases, the source may never be identified.

June 26 (UPI) — The U.S. Centers for Disease Control and Prevention on Friday increased its response level to the Ebola outbreak in the Democratic Republic of the Congo and Uganda.

In an update to reporters, Satish Pillai, the Ebola response incidence manager at the CDC, said public health officials were concerned about the rapid increase in and geographic spread of cases of the deadly virus. She said the CDC has upgraded its response to Level 1, making it a top priority.

“Elevating the response level reflects the urgency, scale and complexity of the outbreak, and allows [the] CDC to bring additional resources to support the coordination and operational needs of our response,” Pillai said.

The World Health Organization has confirmed more than 1,000 cases of Ebola and more than 260 deaths from the disease since the outbreak, which began in May. Most of the cases have been reported in eastern DRC, with a smaller number of cases spreading across the border into Uganda.

This Ebola outbreak has been linked to the Bundibugyo virus, making it particularly challenging to treat. Unlike the Ebola-zaire strains of the virus, there are no approved approved therapeutics or vaccines for the Bundibugyo strain, the WHO said.

Ebola was first identified in central Africa in 1976. The virus, which has a two- to 21-day incubation period, causes fever, fatigue, muscle pain, headache, sore throat, vomiting, diarrhea, rash, and, in some cases, internal and external bleeding. It can be transmitted from animals to humans and in human-to-human contact, including sexual intercourse.

While there’s no proven treatment specifically for the virus, people can survive through treatment of the symptoms, including oral and intravenous fluids, and immune and drug therapies.

The ⁠number of confirmed cases in ⁠the country has ​increased to 837, including 196 deaths.

The current Ebola outbreak in the Democratic Republic of Congo (DRC) could become deadlier than the worst outbreak on record, which killed more than 11,000 people, says the head of Africa’s Centres for Disease Control and Prevention (Africa CDC).

⁠The ⁠number of confirmed cases in ⁠the country has increased to 837, including 196 deaths, ‌government data showed on Tuesday.

“If we don’t stop the outbreak very soon, it will be worse than what we had in West Africa and eastern DRC,” Africa CDC Director-General Jean Kaseya said during a virtual meeting of African leaders and international donors in Burundi on Tuesday.

Speaking to Al Jazeera, Kaseya said tens of thousands of people who may have been exposed to Ebola had not yet been traced or contacted.

“The contact tracing is a major indicator and a major issue. We are missing more than 26,000 people, and we don’t know where they are, and we don’t know if they are contaminating other people.”

A ⁠Red Cross official said that the epidemic had not yet peaked in the country.

“We ⁠are afraid that this could last one year to end this disease,” Bruno Michon, operations manager for the International Federation of Red Cross and Red Crescent Societies, said.

The response has been hampered by a lack of treatment centres and by community resistance to stringent hygiene measures. Health officials said that, more than a month since ⁠the outbreak was declared, the true scale was still unknown.

The bodies of ⁠Ebola victims are highly infectious after death, and unsafe traditional burials – in which family members handle ⁠the body without proper protective equipment – are a leading driver of transmission.

So far, the continent has raised less than a fifth of the $518 million it is seeking to bolster measures to contain the outbreak, according to Burundi’s President Evariste Ndayishimiye, who also chairs the African Union.

The shortfall has raised concern among authorities, who fear the consequences could be devastating if the virus is not brought under control quickly.

There is no approved treatment or vaccine for this strain of Ebola. The World Health Organization (WHO) says it could take up to nine months for a vaccine to be ready.

Neighbouring Uganda has recorded 19 cases, 14 of them among people who had travelled from the DRC. The country has also reported two deaths.

June 10 (UPI) — The American College of Obstetricians and Gynecologists released its recommended maternal vaccine schedule Wednesday, breaking for the first time on advice from the U.S. Center for Disease Control and Prevention.

The group advises four vaccines during pregnancy, including a COVID-19 shot; a flu shot; a tetanus, diphtheria and pertussis (Tdap) vaccine; and a vaccine that protects the fetus against respiratory syncytial virus, commonly called RSV.

“Changing national recommendations coupled with rampant vaccine misinformation are resulting in confusion for both patients and healthcare professionals,” Camille Clare, ACOG president, said in a statement.”It is incredibly important for the public to have access to reliable,evidence-based information on maternal immunizations from a trusted source.”

The schedule also includes additional vaccines for those with certain risk factors and for those postpartum and breastfeeding. Thirteen other medical societies, including the American Academy of Pediatrics, the American Academy of Family Physicians and the American College of Nurse-Midwives, endorsed the list.

The CDC, under the leadership of Health and Human Services Secretary Robert F. Kennedy Jr., a vaccine skeptic, changed its recommended maternal vaccine schedule last year, removing the flu and COVID-19 shots, The Hill reported.

In changing the schedule in 2025, the CDC did not its usual process of using a panel of vaccine experts to review studies and make advice. The American Academy of Pediatrics and some U.S. states have also broken with the new CDC guidelines.

“Immunization is an essential part of preventative care forpeople who are pregnant, postpartum and lactating — and for their infants,” ACOG said in its recommendations. “OB-GYNs can reduce the frequency of vaccine-preventable diseases by being aware of current vaccine recommendations, counseling patients to receive appropriate vaccines and integrating vaccination into routine clinical practice.”

WASHINGTON — President Trump on Friday gave his endorsement to a January study by the Department of Health and Human Services that calls for cutting the number of vaccines recommended for every American child.

An executive order from Trump directs federal agencies to align their policies behind the study, which recommended an overhaul long called for by Health Secretary Robert F. Kennedy Jr. The study found that the United States recommends more childhood vaccines than many peer nations.

The Trump administration previously moved to narrow the number of recommended childhood vaccines in response to the report, but the move was blocked by a federal judge in Massachusetts. The administration is appealing the decision.

The study recommends vaccinating all children against 11 diseases. Several others would be recommended only for high-risk groups or when doctors recommend them in what’s called “shared decision-making.” That includes vaccines for flu, rotavirus, hepatitis A, hepatitis B, some forms of meningitis and RSV.

Trump’s order adds weight behind the study at a time when the administration had appeared to be trying to shift focus away from Kennedy’s more contentious vaccine policies and toward topics with more widespread support among medical professionals, such as healthful eating.

The order directs the Centers for Disease Control and Prevention to review the study and “take any appropriate steps” to update its vaccine recommendations. It says the CDC should “provide maximum flexibility to parents and doctors” and directs agencies to make sure all actions, regulations and funding are aligned with the study.

The order adds that any changes should ensure that Americans retain their current access to vaccines.

States, not the federal government, have the authority to require vaccinations for schoolchildren. While CDC requirements often influence those state regulations, some states have begun creating their own alliances to counter the Trump administration’s guidance on vaccines.

Trump directed the Department of Health and Human Services to carry out the study in December.

Kennedy is a longtime activist against vaccines and has sought ways to inject his skepticism about the shots into national guidance, running counter to the overwhelming consensus of medical experts. Last year, he announced the CDC would no longer recommend COVID-19 vaccines for healthy children and pregnant women, though public health experts said they saw no new data to justify the change.

Last June, he fired a 17-member CDC vaccine advisory committee and later installed several of his own replacements, including vaccine skeptics.

The January report found that vaccine recommendations for American children had increased in recent decades. It also highlighted countries where no vaccines are required to attend school.

May 23 (UPI) — The Centers for Disease Control and Prevention on Saturday added two more airports that travelers to the United States can be routed through for Ebola screening when entering the country.

The enhanced travel screening announced earlier this week by the CDC and the Department of Homeland Security is meant to screen people for the virus on entry to the country if they have been in the Democratic Republic of Congo, South Sudan or Uganda.

The outbreak, which started in the DRC and has spread to neighboring South Sudan and Uganda, is estimated to have 750 suspected cases and 177 suspected deaths, the World Health Organization on Friday said, adding that the “real scale of the outbreak is likely far larger.”

The CDC first issued restrictions on Thursday for Americans returning to the United States to be screened at Washington Dulles International Airport in Washington, D.C., before continuing on to their final destinations.

The two additional airports will be Hartsfield-Jackson Atlanta International Airport, which started to accept travelers at 11:59 p.m. EDT on Friday, and George W. Bush Intercontinental Airport in Houston, which will start to accept travelers on Tuesday, May 26, at 11:59 p.m. EDT, the CDC said on Saturday.

“These travelers will have their air travel re-routed to arrive at select airports,” CDC officials said in the update.

The enhanced health screening includes being escorted to a designated screening area; completing a questionnaire about their travel history and symptoms; having their temperatures checked using non-contact thermometers; and observation by CDC staff for signs of illness.

“Travelers with fever or other symptoms that could be Ebola will receive additional evaluation by a CDC public health officer,” the agency said.

“If the assessment shows that a traveler may be sick with Ebola, the traveler will be transferred to a hospital for further medical evaluation,” it said.

The WHO on Friday raised the national risk assessment during the outbreak in the DRC to “very high,” but officials said that global risk for infection with the Bundibugyo strain of the Ebola virus, for which there is no approved vaccine.

WHO Director-General Tedros Adhanom Ghebreysus during a meeting on Friday thanked the efforts of neighboring nations in Africa who have assisted during the outbreak, as well as the various regional and global health agencies that also have done so.

Although the United States last year pulled out of the WHO, the U.S. State Department said on Saturday that it has activated a dedicated Ebola Response Task Force that is led by “senior experts with direct experience managing prior Ebola outbreaks” in 2014 and 2018.

The department also has deployed a Disaster Assistance Response Team and provided $32 million in assistance to U.S. partners in the region, it said in a press release.

May 18 (UPI) — The U.S. Centers for Disease Control and Prevention on Monday restricted non-U.S. passport holders from entering the United States if they have been in Uganda, the Democratic Republic of the Congo or South Sudan in the past 21 days.

The agency made the announcement as there have at least 346 cases and 88 deaths in the DRC, on top of several cases that have been confirmed in nearby nations in people who been there, the CDC said over the weekend.

The CDC said that is coordinating with various agencies and companies to manage travelers who have been exposed to Ebola as it also deploys employees to support containment of the outbreak in the three nations.

“CDC assess the immediate risk to the general U.S. public as low, but we will continue to evaluate the evolving situation and may adjust public health measures as additional information becomes available,” the agency said in a situation summary.

In the last five days, the World Health Organization confirmed that the Ebola virus circulating in the three countries right now is the Bundibuyo virus, one of four known strains that have affected humans since Ebola was discovered in mid-1970s.

Although there is an approved, licensed vaccine against Ebola which has successfully been used to quell outbreaks, the vaccine — called Ervebo — only protects against acquisition of the Zaire species of Ebola virus, making it useless in the current outbreak, according to the CDC.

WHO on Saturday declared the outbreak a public health emergency of international concern.

In its update, WHO said that there are “significant uncertainties to the true number of infected persons and geographic spread associated with this event at the present time. In addition, there is limited understanding of the epidemiologic links with known or suspected cases.”

Ebola spreads from wild animals to humans and from human to human through direct contact with blood or other bodily fluids from infected individuals, and carries a case fatality rate of roughly 50%.

A number of affected Americans have reportedly been exposed to the virus during the outbreak.

The CDC has recommended that people who have traveled through the two countries in the last 21 days should immediately seek medical attention if they develop Ebola symptoms, which can include fever, weakness, vomiting, diarrhea or unexplained bleeding.

In addition to roughly 30 CDC employees dispatched to the region, and will join officials from several other global and regional health agencies, the WHO is expected to convene an emergency committee to advise the agency’s director-general on its response the outbreak.

NEW YORK — No quick dispatching of disease investigators. No televised news conference to inform the public. No timely health alerts to doctors.

In the midst of a hantavirus outbreak that involves Americans and is making headlines around the world, the U.S. government’s top public health agency, the Centers for Disease Control and Prevention, has been uncharacteristically missing in action, according to a number of experts.

To President Trump, “we seem to have things under very good control,” as he told reporters Friday evening.

To experts, the situation aboard a cruise ship has not spiraled because, unlike COVID-19 or measles or the flu, hantavirus does not spread easily. It has been health experts in other countries, not the United States, who have been dealing primarily with the outbreak in the last week.

“The CDC is not even a player,” said Lawrence Gostin, an international public health expert at Georgetown University. “I’ve never seen that before.”

Not until late Friday did CDC actions accelerate.

Health officials confirmed the deployment of a team to Spain’s Canary Islands, where the ship was expected to arrive early Sunday local time, to meet the Americans onboard. They said a second team will go to Offutt Air Force Base in Nebraska as part of a plan to evacuate U.S. passengers from the ship to a University of Nebraska quarantine center for evaluation and monitoring. Also, the CDC issued its first health alert to U.S. doctors, advising them of the possibility of imported cases.

At their first briefing, held Saturday by telephone only for invited reporters, officials pledged to be transparent in updating the public but said the media could not cite the speakers by name under rules set by aides to Health Secretary Robert F. Kennedy Jr. They did not directly answer a question about whether the U.S. passengers could leave the university medical facility when they wanted.

The CDC’s diminished role in this outbreak is an indicator the agency is no longer the force in international health or the protector of domestic health that it once was, some experts said.

The hantavirus outbreak is “a sentinel event” that speaks to “how well the country is prepared for a disease threat. And right now, I’m very sorry to say that we are not prepared,” said Dr. Jeanne Marrazzo, chief executive officer of the Infectious Diseases Society of America.

How the outbreak unfolded

Early last month, a 70-year-old Dutch man developed a feverish illness on a cruise ship traveling from Argentina to Antarctica and some islands in the South Atlantic. He died less than a week later. More people became sick, including the man’s wife and a German woman who both died.

Hantavirus was first identified as a cause of sickness of one of the cases on May 2. The World Health Organization swung into action and by Monday was calling it an outbreak. About two dozen Americans were on the ship, including about seven who disembarked last month and 17 who remained on board.

It’s WHO taking center stage

For decades, the CDC partnered with the WHO in such situations. The CDC acted as a mainstay of any international investigation, providing staff and expertise to help unravel any outbreak mystery, develop ways to control it and communicate to the public what they should know and how they should worry.

Such actions were a large reason why the CDC developed a reputation as the world’s premier public health agency.

But this time, the WHO has been center stage. It made the risk assessment that has told people the outbreak is not a pandemic threat.

“I don’t think this is a giant threat to the United States,” said Jennifer Nuzzo, director of Brown University’s Pandemic Center. But how this situation has played out “just shows how empty and vapid the CDC is right now,” she said.

Tumult under Trump

The current situation comes after 16 tumultuous months during which the Trump administration withdrew from the WHO, has restricted CDC scientists from talking to international counterparts at times and embarked on a plan to build its own international public health network through one-on-one agreements with individual countries.

The administration has laid off thousands of CDC scientists and public health professionals, including members of the agency’s ship sanitation program.

As this was playing out, Kennedy said he was working to “restore the CDC’s focus on infectious disease, invest in innovation, and rebuild trust through integrity and transparency.”

Waiting to hear from the CDC

The CDC has not been completely silent on hantavirus.

The agency on Wednesday issued a short statement that said the risk to the American public is “extremely low,” and described the U.S. government as “the world’s leader in global health security.”

Said Nuzzo: “Not only was that not helpful, it actually does damage because a core principle of public health communications is humility.”

The CDC’s acting director, Dr. Jay Bhattacharya, posted a message on social media that the agency was lending its expertise in coordinating with other federal agencies and international authorities. Arizona officials this week said they learned from the CDC that one of the Americans who left the ship — a person with no symptoms and not considered contagious — had already returned to the state. WHO officials said the CDC has been sharing technical information.

The CDC also is “monitoring the health status and preparing medical support for all of the American passengers on the cruise,” Bhattacharya wrote.

But federal health officials have mostly been tight-lipped, declining interview requests.

COVID-19 comparison

In interviews this week, some experts made a comparison with a 2020 incident involving the Diamond Princess, a cruise ship docked in Japan that became the setting of one of the first large COVID-19 outbreaks outside China.

The CDC sent personnel to the port, helped evacuate American passengers, ran quarantines, shared genetic data on the virus, coordinated with the WHO and Japan, held public briefings and rapidly published reports “that became the world’s reference data on cruise ship COVID transmission,” said Dr. Tom Frieden, a former CDC director.

Some aspects of the international response to the Diamond Princess were criticized, and it did not halt the outbreak or stop COVID-19’s spread across the world. But some experts say it was not for the CDC’s lack of trying.

“The CDC was right on top of it, very visible, very active in trying to manage and contain it,” Gostin said, while the agency’s work now is delayed and subdued.

Instead of working with nearly all of the world’s nations through the WHO, the Trump administration has pursued bilateral health agreements with individual nations for information sharing, public health support, and what it describes as “the introduction of innovative American technologies.” Roughly 30 agreements are currently in place.

That’s not sufficient, Gostin said. “You can’t possibly cover a global health crisis by doing one-on-one deals with countries here and there,” he said.
