MEXICO CITY Health authorities in Mexico said Wednesday that 28 people have died and 9,074 cases have been reported since a measles outbreak that began in 2025. Low vaccination coverage has made Mexico the leading country in the Americas in measles infections. The first case, recorded in February last year, occurred in the northwestern state of Chihuahua. The border state experienced a surge in cases last year, with more than 580 confirmed by late April and as many as 4,000 by August. Regarding
