U.S. Measles Cases Surge to 483, Spanning 19 States

Texas remains the epicenter with 400 cases, as public health officials warn of severe outcomes and urge vaccination to curb the outbreak.

The U.S. has reported 483 confirmed measles cases in 2025, a 28% increase in the past week, according to the CDC.
Texas accounts for 400 cases, with New Mexico reporting 44 cases, as the outbreak spreads to 19 states.
At least 41 hospitalizations have occurred, predominantly affecting children, with complications such as pneumonia and vitamin A toxicity reported.
Declining vaccination rates, fueled by misinformation, are cited as a key factor, with some Texas counties reporting exemption rates exceeding 17%.
The CDC and WHO emphasize the importance of the MMR vaccine, which is 97% effective with two doses, and advise travelers to check their vaccination status before visiting affected areas.
