Measles Outbreak Ends as Vaccination Rates Show Signs of Improvement

The largest measles outbreak in the U.S. in decades, centered in South Carolina, has officially concluded after nearly 1,000 confirmed cases and 21 hospitalizations over six months. No new cases have been reported for over 42 days, indicating effective control measures. This outbreak, alongside a similar situation in West Texas, has contributed to a record year for measles cases nationwide, prompting concerns about vaccination rates. However, early indications suggest a rise in MMR vaccinations among children, possibly due to increased awareness of the disease's severity. Public health officials emphasize the importance of vaccination and community health efforts in combating outbreaks.

Key Details: • No new measles cases reported in South Carolina for over 42 days. • The outbreak lasted approximately six months, starting in October. • Public health response costs in South Carolina reached about $2 million. • MMR vaccination rates among children under 4 saw a significant increase. • CDC reports 97% of 3-year-olds had at least one MMR dose in 2025.
