Public health leader rooted in Johns Hopkins research
Multiple sources report a rebound in measles cases across the U.S., with 2,260 confirmed cases now documented in 44 states and D.C. Public health officials say vaccination coverage below 95% threatens herd immunity and risks losing measles elimination status. A review in November will decide on that status.
The CDC reports 2,318 measles cases in 2026, making it the worst year in decades. Outbreaks in South Carolina, Utah and Arizona have prompted renewed concern over vaccination coverage as officials weigh loss of measles-free status.
The multistate cyclospora outbreak is now linked to iceberg lettuce from Taylor Farms’ central Mexico operations and has affected at least nine states, with thousands of cases and hundreds of hospitalizations reported. Taylor Farms has issued a voluntary recall, and FDA and CDC investigations continue as officials warn consumers to avoid recalled lettuce.
California has enacted a law requiring two standardized labels for food dating—one for quality and one for safety—aimed at reducing consumer confusion and food waste. Other states are watching as federal rules remain limited to baby formula. The shift comes amid widespread use of more than 50 date labels in the US and consumer behavior that discards food approaching those dates.
President Trump has signed an executive order directing federal health officials to cut the federal recommended childhood vaccine list, to split the combined MMR vaccine into separate measles, mumps and rubella doses once single‑disease products are available, and to space routine immunisations across separate medical visits. Public health groups and drugmakers have said the changes lack scientific support and will increase missed vaccinations during a major U.S. measles outbreak.
The White House has issued an executive order reducing federal vaccine recommendations to 11 core shots and urging the separation of the MMR vaccine into three injections. Physicians warn the move risks confusion and slower protection, while public health groups stress that CDC guidance remains unchanged and vaccines should proceed as recommended.
The ICE crackdown is expanding beyond checkpoints into terminals and jet bridges, prompting pushback from airlines and concerns from labor groups. New data show daily arrests at airports rising, while legislators debate data-sharing and oversight. Several incidents have highlighted tensions between enforcement and airline operations.
Scientists have used tooth enamel chemistry to estimate Tyrannosaurus rex’s body temperature at about 36°C, placing it among warm‑blooded animals. The research, based on clumped isotope thermometry, is published in Science Advances and relies on enamel from three teeth from Hell Creek Formation fossils.
