Bay Area health officials urge vaccinations as measles cases continue to surge nationwide

Bay Area health officials are urging parents and international travelers to follow vaccination guidelines to prevent measles infections over the summer as the United States grapples with a sharp increase in measles outbreaks that began in 2025.

Measles is a highly contagious viral disease; in a room where one person is infected, nine out of 10 unvaccinated people will contract the disease. Symptoms can include fever, cough, runny nose, conjunctivitis, and a rash of flat, red spots.
