In 2024, an estimated 95,000 people died from measles globally, most of them children under five. Vaccination has prevented nearly 59 million deaths since 2000. A child dying from a vaccine preventable disease is not an acceptable new normal. It is a public health failure.

Surveillance → detection → lab confirmation → cluster ID → traceback → inspection → action. Weakening one layer may not cause an outbreak. Weaken enough, and you increase the time between the first infection and finding what is making people sick. This is why public health infrastructure matters.

At this point, epidemiologists aren’t tracking outbreaks. We’re collecting pathogens like Pokémon cards. Salmonella. Listeria. E. coli. Cyclospora. Gotta catch ’em all, apparently. 🦠🤮

The Nino 3.4 sea surface temperature (preliminary) is at 29.65°C, as of August 9th, the 72nd consecutive record daily high, on its way to crushing the previous record high of 29.82°C, set November 17th, 2015. The Nino 3.4 anomaly currently sits at 2.77°C above the 1991-2020 average.

FDA approved the Moderna mRNA flu vaccine, which is great news for everyone! In clinical trials it outperformed existing flu vaccine technology so well that not even Vinay Prasad could cancel it. I talked to Scott Tong at @npr.org @hereandnow.bsky.social about it www.wbur.org/hereandnow/2...

In response to this administrations lack of response. The way to stop #Ebola from reaching the U.S. is not pretending borders are magic. It’s funding the response teams where the outbreak is happening. Pathogens do not care about slogans or borders. They care about system failure.

The #Ebola outbreak in #DRC and #Uganda is not occurring in isolation. It is unfolding inside one of the largest disruptions to global health financing in recent memory. That context matters epidemiologically. Not politically. Epidemiologically.

You cannot gut global health trust, undercut international cooperation and then act surprised when another country does not want to become the holding room for a Ebola exposure problem.

Ebola did not suddenly become urgent when the world started paying attention. The outbreak in DRC and Uganda was circulating for weeks before detection, with hundreds of suspected cases now reported. That is the real warning that we need to continue to look at.

Motivated by the devastation the Spanish flu inflicted on WW1 troops, the US military was key in the development of #flu vaccine. Keeping troops battle ready is critical, which makes Hegseth's decision to drop mandatory flu shots ill-advised, Paul Friedrichs writes. www.statnews.com/2026/04/23/m...

People are focused on the blasts. I’m focused on the air and the environment. Burning petroleum in a mountain valley city of 10M people like we are watching in #Iran is a mass exposure event. And it’s not just one type of PM. It’s the full spectrum, each with its own damage pathway.

Pulling back on #biodefense weakens our ability to detect, model and respond to the next threat not just at the national level but globally as well. As climate change and urbanization reshape transmission patterns, preparedness isn’t optional. It’s foundational to public health.

Post-storm reality: empty shelves. The system needs time to recover now. With natural disaster risks rising, we must be ready for "anything." At least with Individual preparedness it buys you independence so you aren't waiting on a system that’s hitting reset button again & again to recover.

I’ve gotten a few messages about #NIPAH cases in India & COVID style airport protocols. Extra surveillance can feel scary, but it does not mean it is the next pandemic. It means public health is doing standard containment and monitoring so we can catch signals early and prevent any global spread.

Dr. Bill Foege was a giant who helped deliver smallpox eradication, one of public health’s greatest achievements. He changed the game by advancing surveillance containment, often called ring vaccination. His legacy lives on in each of us fighting for public health prevention in our communities.

Picking up a few supplies for this storm had me thinking about how exposures keep widening. Heat lingers longer. Smoke ignores state lines. Hurricanes like Helene push further inland.

Off season heat can bring real disease risks. Warmer winters can extend transmission windows, affect vector and pathogen survival and leave communities more vulnerable when systems are not heat ready. It has been unusually warm in SC for January. These are not good signs.

Reminder that #Measles has an R0 around 12 to 18. It is airborne and can hang in the air for up to 2 hours after someone leaves. Translation: if susceptibles exist, measles will find them. Vaccinating or boosting is the intervention to reduce your risk, not a debate club.
