Measles’ Most Deceptive Trait
Most cases are mild, obscuring the disease’s worst outcomes.
TL;DR
- In the early 1960s, measles was a near-universal childhood illness in the U.S., with virtually every child expected to contract it before finishing middle school.
- The introduction of the measles vaccine in 1963 and subsequent widespread vaccination efforts led to the disease's elimination from the U.S. by 2000.
- Recent outbreaks are occurring across the country due to drops in vaccination rates, with the U.S. now experiencing nearly a year of continuous measles transmission.
- Despite its potential for severe complications like pneumonia, brain swelling, deafness, and blindness, measles was often perceived as a mild illness, leading to vaccine hesitancy.
- Measles vaccination is highly effective, but requires high community immunity (92-94%) to prevent outbreaks, a threshold that is currently being threatened.
- The resurgence of measles poses significant public health and economic costs, including strain on healthcare systems, lost workdays, and the need for extensive contact tracing.
