Notes from the Field: Subacute Sclerosing Panencephalitis Death - Oregon, 2015

Area of Science:

• Neurology
• Pediatrics
• Public Health

Background:

• Measles is a highly contagious viral illness.
• Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, and fatal neurological complication of measles infection.
• Measles vaccination is a key public health intervention.

Observation:

• A 14-year-old boy diagnosed with SSPE died in 2015.
• The patient had received a measles vaccination in infancy but contracted measles at age 1.
• Neurodegenerative symptoms began 13 years after the measles infection.

Findings:

• The case report details the clinical progression of SSPE in a vaccinated individual who experienced a wild-type measles infection.
• Investigation confirmed the link between the prior measles illness and the subsequent development of SSPE.
• Medical records and parental interviews were used to reconstruct the patient's history.

Implications:

• This case underscores the critical importance of measles vaccination in preventing severe complications like SSPE.
• Maintaining high vaccination rates is essential for community protection against measles and its sequelae.
• The findings reinforce the long-term neurological risks associated with measles infection, even in vaccinated populations.
