A measles outbreak, originating in Texas in January, has spread across 29 US states, resulting in nearly 900 confirmed cases and three deaths. The majority of cases (646) are in Texas, with 94 hospitalizations nationwide. The CDC reports 97% of cases involve unvaccinated or unknown vaccination status individuals. Health officials warn of further increases and emphasize the importance of the MMR vaccine. Initial downplaying of the outbreak by HHS Secretary Robert F. Kennedy Jr. was followed by a call for vaccination after attending a child's funeral.
