Episode notes
Measles Outbreak's Severity and Spread
- Measles cases have surged to 935 confirmed in the U.S. by May 1, originating from West Texas and spreading to 29 states.
- The outbreak mostly affects unvaccinated children and is causing severe complications including deaths, underscoring its high contagiousness.
Understanding Measles Elimination Status
- Measles elimination means no continuous endemic transmission for 12 months in a region.
- The U.S. gained this status in 2000 but the current outbreak could disqualify it if transmission persists a year, risking elimination status.
Vaccination Decline Risks Measles Fight
- Declining vaccination rates, worsened by the pandemic and anti-vaccine rhetoric, increase measles outbreak risk.
- Measles requires about 95% vaccination for herd immunity; even small drops can trigger severe outbreaks in communities with low vaccination.
