Measles is making a troubling comeback in the U.S., with over 700 confirmed cases reported across 25 states so far in 2025. While some online debates downplay the severity, the reality is that measles is one of the most contagious viruses known, and nearly all recent cases have occurred in people who were unvaccinated or whose vaccination status is unknown. Hospitalisations and even deaths have been reported, reminding us that this isn’t just a childhood illness from the past—it’s a serious public health threat. Understanding how measles affects the body and brain, and boosting vaccination efforts, are key to stopping this outbreak and preventing future ones.
