cases

Two lawsuits accusing the world’s largest social media companies of harming children begin this week, marking the first legal efforts to hold companies like Meta responsible for the effects their products have on young users.

Opening arguments began today in a case brought by New Mexico’s attorney general’s office, which alleges that Meta failed to protect children from sexually explicit material. A separate case in Los Angeles, which accuses Meta and the Google-owned YouTube of deliberately designing their platforms to be addictive for children, is set to begin later this week.

TikTok and Snap were also named in the original California lawsuit but later settled under undisclosed terms.

The New Mexico and California lawsuits are the first of a wave of 40 lawsuits filed by state attorneys general around the US against Meta, specifically, that allege that the social media giant is harming the mental health of young Americans.

New Mexico case

In the opening argument in the New Mexico case, which was first filed in 2023, prosecutors told jurors on Monday that Meta – Facebook and Instagram’s parent company – had failed to disclose its platforms’ harmful effects on kids.

“The theme throughout this trial is going to be that Meta put profits over safety,” said lawyer Donald Migliori, who is representing the state of New Mexico against Meta.

“Meta clearly knew that youth safety was not its corporate priority… that youth safety was less important than growth and engagement.”

Prosecutors say they will provide evidence and testimony that Meta’s algorithms and account features not only enticed young people and made them addicted to social media, but also fostered a “breeding ground” for predators who target children for sexual exploitation.

Late last month, in the process of discovery, the New Mexico attorney general’s office said the company did not put in safeguards to protect children from accessing sexualised chatbots on Facebook and Instagram.

In emails obtained by the court, some of Meta’s safety staff had expressed objections that the company was building chatbots geared for companionship, including sexual and romantic interactions with users, according to the Reuters news agency.

The artificial intelligence chatbots were released in early 2024. The documents cited in the state’s filing do not include messages or memos authored by Meta CEO Mark Zuckerberg. In October 2025, Meta added parental controls to the chatbots.

California case

The California case is more wide-reaching and alleges that Meta and YouTube, which is a unit of Alphabet-owned Google, used deliberate design choices that sought to make their platforms more addictive to children to boost profits.

The case centres around a 19-year-old identified only by the initials KGM. The case could determine how thousands of other, similar lawsuits against social media companies will play out.

KGM claims that her use of social media from an early age made her addicted to the technology and exacerbated her depression and suicidal thoughts.

“Borrowing heavily from the behavioral and neurobiological techniques used by slot machines and exploited by the cigarette industry, Defendants deliberately embedded in their products an array of design features aimed at maximizing youth engagement to drive advertising revenue,” the lawsuit says.

Executives, including Zuckerberg, are expected to testify at the trial, which will last six to eight weeks. It is unclear if they will attend the New Mexico case.

The tech companies dispute the claims that their products deliberately harm children, citing a bevvy of safeguards they have added over the years and arguing that they are not liable for content posted on their sites by third parties.

“Recently, a number of lawsuits have attempted to place the blame for teen mental health struggles squarely on social media companies,” Meta said in a recent blog post. “But this oversimplifies a serious issue. Clinicians and researchers find that mental health is a deeply complex and multifaceted issue, and trends regarding teens’ well-being aren’t clear-cut or universal.

Narrowing the challenges faced by teens to a single factor ignores the scientific research and the many stressors impacting young people today, like academic pressure, school safety, socio-economic challenges and substance abuse.”

A Meta spokesperson said in a recent statement that the company strongly disagrees with the allegations outlined in the lawsuit and that it is “confident the evidence will show our longstanding commitment to supporting young people”.

Jose Castaneda, a Google spokesperson, said the allegations against YouTube are “simply not true”.

“Providing young people with a safer, healthier experience has always been core to our work,” he said in a statement.

High stakes

The outcome of the cases could shape the future of social media.

“In my mind, an existential question for social media services is whether they’re liable for harm suffered by users from using the services. If so, the damages could be more money than the defendants have, Eric Goldman, a professor at the Santa Clara University School of Law, told Al Jazeera.

“We’re talking about massive financial stakes, and we’re also talking about the ability of the plaintiffs to veto or potentially override editorial decisions by the services about what’s in the best interests of their audiences,” he said.

“It’s essentially taking away power from the services to decide and handing it to plaintiffs’ lawyers. So, not only could there be existential damages, but there could also be a massive loss of editorial control over their services. The stakes could not be higher for social media services or the internet.”

Goldman said this was because the same argument could be used to shape claims against video game makers and generative AI, which refers to AI that can create original content, including text and video.

“If these theories work against social media, they might also work against video games, against generative AI, and who knows what else. That’s why I said the stakes are so high for the internet,” he added.

There are already lawsuits that claim that interactions with OpenAI’s ChatGPT led to instances of suicide and murder-suicide.

On Wall Street, Meta stock is trending up by more than 3 percent in midday trading.

Feb. 7 (UPI) — Federal health officials reported 145 new measles cases amid outbreaks across 20 states over the past week, raising the nation’s total to 733 so far this year.

South Carolina, by far, has recorded the most measles cases among states this year after an outbreak began in the fall and has reported a total of 920 confirmed cases since then — including 44 new ones during the past week.

The Centers for Disease Control and Prevention said the nation totaled 733 cases for the year as of Thursday, including 727 across 20 states. Another six cases were confirmed among international travelers.

The majority of cases, 671, or 92%, are linked to outbreaks that began in 2025 and have continued into 2026. Another nine cases are associated with new outbreaks reported so far in 2026.

The number of cases this year is much lower than the 2,276 cases reported across 45 states in 2025, but the number could top last year’s total if the infection rates continue throughout the year.

“Because it’s such an infectious virus, whenever you see measles outbreaks, it highlights areas of the country or communities in which vaccination rates are low,” Dr. Demetre Daskalakis told ABC News. Daskalakis formerly led the CDC’s disease-tracking unit.

In addition to South Carolina, cases have been reported in Arizona, California, Florida, Georgia, Idaho, Kentucky, Minnesota, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Dakota, Utah, Virginia, Washington and Wisconsin.

The United States in 2000 declared measles had been eradicated, but recent outbreaks among international travelers and the unvaccinated, plus this year’s rapid start, likely will end that designation.

Before 2025, the country averaged 180 measles cases per year, but the 2026 numbers already are more than four times that number.

Infants, children and teens account for the majority of cases, 203 among those under age 5 and 417 among those from ages 5 through 19, the combined total of which accounts for 85% of all cases.

Those ages 20 and over account for 92 and 13% of cases, and another 21 cases, 3% are among unknown ages.

Vaccination status plays an even greater role than age in the current measles outbreak.

Those who are unvaccinated or whose vaccination status is unknown account for 689 cases — equal to 94% — so far this year.

Patients who have received just one dose of the measles, mumps and rubella vaccine account for another 14 cases, which is equal to 2%, while those who are fully vaccinated account for 30 cases and 4% of the current total. Those percentages are about the same as in 2025.

So far this year, 23 people have been hospitalized, which is equal to 3% of all cases, and no deaths have been reported so far this year.

The Pan American Health Organization (PAHO), a United Nations agency, has issued a new report warning of an uptick in measles cases throughout the region.

On Wednesday, the organisation issued an epidemiological alert that called for member states to strengthen “routine surveillance and vaccination activities” in order to combat the spread of the disease.

“The sharp increase in measles cases in the Americas Region during 2025 and early 2026 is a warning sign that requires immediate and coordinated action by Member States,” PAHO said in a statement.

Overall, in the first three weeks of 2026 alone, PAHO documented 1,031 cases of measles in the Americas. Throughout 2025, a total of 14,891 cases were confirmed.

Some of the biggest outbreaks the PAHO highlighted were unfolding in North America, with countries like the United States, Mexico and Canada facing high numbers of cases.

What is measles?

Measles is a highly contagious airborne virus capable of infecting nine out of every 10 people exposed to it, if they are unvaccinated.

In most cases, symptoms of the disease clear up within several weeks. However, measles can be deadly or cause life-altering health complications, particularly among young children.

Some sufferers find themselves with ear infections and lung inflammation. Others experience pneumonia or encephalitis, a swelling of the brain that can cause lasting damage, including seizures and memory loss.

The only way to prevent measles and halt its spread is by taking a vaccine. That care is often administered through a combination vaccine known by the acronym MMR, for measles, mumps and rubella.

Doctors typically advise patients to get vaccinated early. For healthy children, the general guidance is to receive the first MMR dose before 15 months of age. The second and final dose is recommended before age six.

The MMR vaccine is widely considered safe. But in countries like the US, vaccination rates have fallen in recent years, in part due to conspiracy theories and misleading statements.

The country’s Health and Human Services Secretary Robert F Kennedy Jr, for instance, has previously asserted that the vaccine “wanes very quickly”, despite the fact that it offers lifelong protection.

Kennedy has also claimed there were health risks associated with the vaccine. But experts, including at the US Centers for Disease Control and Prevention (CDC), have repeatedly maintained that most people encounter no serious problems – and that the vaccine is far safer than exposure to measles itself.

“There have been no deaths shown to be related to the MMR vaccine in healthy people,” the Infectious Diseases Society of America says on its website.

High numbers in North America

According to PAHO’s report on Wednesday, the US has seen 171 new cases of measles in the first three weeks of 2026. The country experienced a total of 2,242 cases in 2025.

One of the ongoing outbreaks has been in South Carolina, where 876 incidents of measles have been reported in recent months. Of that total, 800 sufferers were unvaccinated, 16 had only received a partial vaccination, and 38 had an unknown vaccination status.

Meanwhile, in Texas, an outbreak resulted in 762 cases of measles between January and August. Two unvaccinated children died in that outbreak, and there were 99 hospitalisations.

In 2000, measles had been declared eliminated from the US, a sign that cases were no longer spreading domestically, though some cases did occur after exposure to the virus abroad.

Mexico, too, had achieved its measles elimination status in 1996, after an extensive vaccination campaign. The entire Americas region was declared measles-free in 2016.

But both the US and Mexico risk seeing their measles elimination status revoked, as outbreaks continue.

In Mexico, for instance, there were 6,428 cases of measles in 2025, the highest of any country in the Americas. For the first three weeks of 2026, there have been 740 more cases.

PAHO typically determines which countries have elimination status, and the organisation has indicated that it will review the situation in the US and Mexico during a virtual meeting on April 13.

Canada, meanwhile, already saw its measles elimination status rescinded in November. It has seen several measles outbreaks since October 2024.

PAHO found that there were 5,436 cases of measles last year, and 67 in the first three weeks of 2026.

The country can win back its elimination status only if it stops measles transmissions resulting from its outbreaks for more than one year.
