Vaccination rates have declined since the pandemic, threatening herd immunity.

Measles spreads easily through airborne droplets and symptoms appear 7-14 days after exposure, including fever, cough, rash, and eye redness. High-risk groups include infants, unvaccinated children, pregnant women, and immunocompromised people. Complications can be severe or fatal. The MMR vaccine is 97% effective with two doses. Restoring high vaccination rates and combating misinformation are essential to prevent outbreaks.
