11 hours agoHealth officials sound alarm as U.S measles cases rise
Declining vaccination rates are leading to increased outbreaks of vaccine-preventable diseases like measles and pertussis in the U.S.
GOARN, which includes more than 310 national public health agencies, United Nations agencies, academic institutions, and nongovernmental groups, helps identify and manage infectious disease outbreaks worldwide. Since it was established in 2000, GOARN says it has helped manage more than 175 global health emergencies across 114 countries.
I am open-minded; I believe in integrative practices, and I agree that the medical establishment can be arrogant and unduly influenced by the pharmaceutical industry, which now funds so much of medical research. But I fully understand Scherer's frustration with his interminable discussions with Kennedy about scientific articles.
The U.S. is no longer part of the World Health Organization. After the Trump administration declared its intention to pull the country out of the global public health agency one year ago, on Thursday it formally followed through, ending its commitment to the organization after 78 years. Withdrawing the U.S. from the WHO was one of Trump's day one priorities. Now, after the required one year notice period, the deed is done.
We now have our first confirmed measles case of 2026 in the Bay Area and the first of 2026 in California as an unvaccinated international traveler apparently brought some back home to San Mateo County. Though first of 2026 may not be that distinct of a deal, considering we saw another new measles case in Contra Costa County when there was still two more days in 2025. [KQED]
Each day, they pore over reams of data about how the virus is evolving worldwide, how well last year's shot performed, and which strains might be easiest to mass produce for a vaccine. The meeting, convened by the World Health Organization twice a year, is a critical moment for the WHO's Global Influenza Surveillance and Response System.
We see the percentage of outpatients' visits for influenza-like illnesses (proven influenza cases and not tested but similar cases) in 2025 and the beginning of 2026, compared to the last few years. The current outbreak is represented by a dark red line that is higher than in previous years and is expected to continue rising with the start of school this week.
Perhaps the most significant milestone was the adoption by WHO Member States of the Pandemic Agreement, a landmark step towards making the world safer from future pandemics. Alongside this, amendments to the International Health Regulations came into force, including a new pandemic emergency alert level designed to trigger stronger global cooperation. And to sustainably finance the WHO's work, governments in a historic show of support increased their contributions to our core budget.
If you're based in the United States, you've probably gotten used to government bodies issuing nationwide alerts - including ones that relate to public health. These have, historically, been good ways for health-conscious people to know what to look out for and for regional public health experts to develop strategies to help keep potential outbreaks contained.Unfortunately, now both individuals and institutions are reckoning with a big question: what to do when those warnings are much smaller in number?
California officials are issuing warnings about a new flu strain that is increasing flu-related cases and hospitalizations statewide, with public health experts across the nation echoing the alerts. A newly emerged influenza A strain, H3N2 subclade K, is already wreaking havoc globally and is affecting hospitals and clinics in California, the California Department of Public Health announced on Tuesday. Although the agency did not provide specific data for California cases, it described the seasonal flu activity as "elevated" in the state.
It's clear that the worst is far from over for the NHS this winter, with hospitals again experiencing a rise in patients admitted with flu and other respiratory virus cases last week.
