Overview
- The school-aged child contracted measles in infancy before vaccine eligibility, later developed subacute sclerosing panencephalitis (SSPE), and died, officials said.
- SSPE is an incurable, progressive brain disorder that typically appears 2–10 years after measles; it affects about 1 in 10,000 cases overall but roughly 1 in 600 after infant infection.
- Los Angeles County’s health officer called the case a painful reminder of measles’ danger and pressed for community immunity to shield those who cannot yet be vaccinated.
- Two MMR doses are about 97% effective; routine dosing is recommended at 12–15 months and again at 4–6 years, with an early dose for some infants traveling internationally.
- The CDC has recorded 1,454 U.S. measles cases this year, mostly in people who were unvaccinated or of unknown status, and LA County withheld identifying details about the child because of privacy rules.
