May 15 (UPI) — The World Health Organization said Friday there have been 10 hantavirus cases reported from the MV Hondius cruise ship and three people have died.

The WHO held a press conference to share an update on the hantavirus outbreak Friday, days after passengers of the cruise ship disembarked to return to their home countries under quarantine. It previously reported 11 cases but that number was revised down to 10.

One American who recently had an inconclusive test has tested negative, said Dr. Maria Van Kerkhove, director of the WHO’s Department of Epidemic and Pandemic Management.

“As of today a total of 10 cases, including three deaths, have been reported to WHO, including eight people who were laboratory confirmed for Andes virus infection and two probable,” Dr. Tedros Adhanom Ghebreyesus, WHO director-general, said during Friday’s press conference.

Forty-one people are being monitored for the hantavirus in the United States. Most U.S. passengers were transported from the ship to the University of Nebraska Medical Center, where they were being monitored in a specially designed medical facility.

Stephen Kornfeld is the only American to test positive for hantavirus. He had flu-like symptoms while aboard the cruise ship and was admitted to the facility in Nebraska. He has since tested negative and has been moved into the facility’s quarantine unit.

“I physically feel great. I have felt great for many, many days,” he told ABC News.

On Thursday, the U.S. Centers for Disease Control and Prevention held a press briefing on its response to the hantavirus. Dr. David Fitter, incident manager for CDC’s hantavirus response, said the risk to the general public is “low.”

“Testing is recommended only for those with symptoms, and decisions are guided by the best available evidence,” Fitter said.

Fitter said the monitoring period for the U.S. passengers is 42 days. He noted that there were passengers who left the ship and returned home before the outbreak and they have been identified.

“Some of these people are at home monitoring their health in close coordination with their state and local health departments, with CDC supporting those efforts,” Fitter said.

WASHINGTON — Amid growing national security concerns, the FBI said Tuesday that it has launched a broad investigation in the deaths or disappearances of at least 10 scientists and staff connected to highly sensitive research, including four from the Los Angeles area.

“The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and state and local law enforcement partners to find answers,” the agency said in a statement.

The FBI’s announcement comes after the House Oversight Committee announced that it would investigate reports of the disappearance and deaths of the scientists, sending letters seeking information from the agencies involved in the federal inquiry as well as NASA, which owns the Jet Propulsion Laboratory in La Cañada Flintridge, where three of the missing or dead scientists worked.

“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” Reps. James Comer (R-Ky.), chairman of the committee, and Eric Burlison (R-Mo.) wrote in the letters.

President Trump told reporters last week that he had been briefed on the missing and dead scientists, which he described as “pretty serious stuff.” He said at the time that he expected answers on whether the deaths were connected “in the next week and a half.”

Michael David Hicks, who studied comets and asteroids at JPL, was the first of the scientists who disappeared or died. He died on July 30, 2023, at the age of 59. No cause of death was disclosed.

A year later, JPL physicist Frank Maiwald died at 61, with no cause of death disclosed.

Two other Los Angeles scientists are part of the string of deaths and disappearances.

On June 22, 2025, Monica Jacinto Reza, a materials scientist at JPL, disappeared while on a hike near Mt. Waterman in the San Gabriel Mountains.

On Feb. 16, Caltech astrophysicist Carl Grillmair was fatally shot on the porch of his Llano home. The Los Angeles County Sheriff’s department arrested Freddy Snyder, 29, in connection with the shooting. Snyder had been arrested in December on suspicion of trespassing on Grillmair’s property.

Snyder has been charged with murder.

There is no evidence at this point that the deaths and disappearances, which occurred over a span of four years, are connected.

A spokesperson for NASA, which owns JPL, said in a statement on X that the agency is “coordinating and cooperating with the relevant agencies in relation to the missing scientists.

“At this time, nothing related to NASA indicates a national security threat,” agency spokesperson Bethany Stevens wrote. “The agency is committed to transparency and will provide more information as able.”

Representatives from Caltech did not immediately respond to a request for comment.
