What is SSPE?
Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, and ultimately fatal degenerative disease of the central nervous system. It develops years after a person has been infected with measles,typically between seven and 10 years post-infection,though cases have been reported decades later CDC – SSPE. The virus persists in the brain, causing inflammation and damage.
Initially, symptoms often mimic the flu – fever, irritability, and behavioral changes.These can be followed by myoclonus (involuntary muscle jerks),seizures,cognitive decline,and eventually,coma and death.
The Link Between Measles and SSPE
While SSPE is rare,it is almost exclusively seen in individuals who have had a measles infection. The measles virus, even after initial recovery, can remain dormant in the brain. In a small percentage of cases, this dormant virus reactivates, leading to the advancement of SSPE.
The Los Angeles County Department of Public Health recently reported a case of SSPE in a child who had contracted measles as an infant. This case underscores the long-term risks associated with measles infection, even if the initial illness appears mild. The department noted that the risk of SSPE is considerably higher for those who contract measles at a young age, estimating a rate of approximately 1 in 600 for infants compared to 1 in 10,000 overall Los Angeles Times – SSPE Death.
Measles Elimination and the Rise of Cases
Thanks to widespread vaccination efforts, measles was declared eliminated in the United States in 2000 CDC – Measles Elimination. However,vaccination rates have been declining in recent years,fueled by misinformation and vaccine hesitancy. This decline has led to a resurgence of measles cases.
As of September 12, 2025, the U.S. measles case count is at a 33-year high,with at least 33 cases reported this year Ars Technica – Measles cases 2025. Tragically, this year has also seen the
