Rare Condition Develops Years After Measles Infection

A school-age child in Los Angeles County has tragically passed away due to a rare complication stemming from a measles infection contracted as an infant. The child had been infected before reaching the age recommended for the first measles vaccine, which is typically administered between 12 and 15 months. A second dose is advised between the ages of 4 and 6.

Though the child initially recovered from the infection, they later developed subacute sclerosing panencephalitis (SSPE), a severe neurological condition that can arise years after a measles infection. SSPE is extremely rare, occurring in roughly 1 in 10,000 unvaccinated measles cases overall, but it affects about 1 in 600 infants who contract the virus before receiving the vaccine.

Understanding SSPE and Its Impact

SSPE causes progressive damage to the brain, resulting in changes in personality or behavior, speech and motor difficulties, epilepsy, and eventually, a vegetative state. Unfortunately, there is no cure for this condition, and it proves fatal in approximately 95% of cases.

This devastating case serves as a stark reminder of the long-term dangers of measles, especially in young children who are too young to be vaccinated.

Rising Measles Cases and the Importance of Vaccination

The United States has reported over 1,450 measles cases this year, the highest number since the disease was declared eliminated in 2000. Experts emphasize that two doses of the measles-mumps-rubella (MMR) vaccine are highly effective, preventing about 97% of measles infections.

To prevent outbreaks, at least 95% of a community must be vaccinated. However, vaccination rates across the country have been declining, leaving vulnerable populations at greater risk.

Infants younger than six months rely on maternal antibodies and community immunity for protection. By ensuring widespread vaccination, individuals not only protect themselves but also help shield the most vulnerable, including infants, pregnant people, and those with compromised immune systems.

A Call for Vigilance

Health officials warn that this tragic loss underscores the importance of maintaining high vaccination coverage. Measles is not just a childhood illness but a serious disease with potential lifelong complications, especially for those who contract it before being fully vaccinated.
