Key Points:

- The CDC reported 3,887 confirmed measles cases across 45 states and Washington, DC, as of October 1, though actual numbers are likely higher due to underreporting and diagnostic delays.
- Declining vaccination rates, driven in part by misinformation and policy changes, have contributed to the resurgence, putting the U.S. at risk of losing its measles elimination status recognized since 2000.
- Measles is highly contagious, with about 90% of unvaccinated exposed individuals contracting the disease, and 20% of those requiring hospitalization; recent outbreaks have resulted in multiple deaths, including pediatric fatalities.
