Antibiotics are essential for modern medicine, but bacteria are evolving and developing resistance, turning routine infections into life-threatening conditions. A global analysis estimates that antibiotic-resistant infections could cause over 39 million deaths by 2050.

The freezer is filled with blue-lidded tubes of cows' blood, ready to be defrosted and used to feed the colony of mosquitoes. Nombuso Princess Bhembe tends the mosquitoes at Eswatini's national insectary, part of the southern African country's push to eliminate malaria.

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.

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.

In children below the age of five, whose immune systems are still developing, the infections can lead to malnourishment; they cause up to 42,000 deaths annually. Soon there may be a vaccine to protect against these infections. In the Lancet Infectious Diseases last month, scientists shared the results of the first study to evaluate the safety and efficacy of an ETEC-controlling vaccine in a large pediatric population in Gambia.

Risks of outbreaks with pandemic potential rise with increasing land-use change, biodiversity loss and climate change. The Pandemic Agreement adopted by the World Health Assembly in 2025 marks a historic shift that establishes the One Health approach as a legally binding obligation for pandemic prevention.

Bats carry a lot of very deadly pathogens like Ebola virus, Nipah, Hendra, coronavirus, and also rabies virus. People are finding more and more bat-borne viruses. When such viruses are transmitted to humans, the results are often fatal so there's a lot of interest in trying to prevent spillover in the first place.

In a study published in Science Advances, researchers in China fed Aedes aegypti mosquitoes blood that contained either a vaccine against Nipah virus or the rabies virus. The viruses, contained in the vaccines, replicated inside the insects and reached their salivary glands, allowing them to pass on the vaccine when feeding on bats or when the bats ate the insects.

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.

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?
