Who is at Highest Risk for Suffering Complications from Measles?
Children under age 5 and adults over 20 are most at risk for complications from measles. The CDC estimates that 30 percent of measles cases result in one or more complications.1 Undernourished or vitamin A-deficient children, along with individuals with immunosuppressive diseases such as HIV/AIDS, are at highest risk of severe complications.2 Adults who contract measles are more at risk of developing acute measles encephalitis than children.3
Immunocompromised individuals are also at higher risk of complications from measles, including those with HIV infection, congenital immunodeficiencies, and those persons with disorders requiring chemotherapeutic and immunosuppressive therapy.4 5
Pregnant women who contract measles may at higher risk for developing complications including miscarriage, pre-term labor, and low birthweight infants. Birth defects have not been associated with measles infection.6
Studies also show that complication rates and deaths are significantly higher, and recovery times longer, in infants and children who acquire measles in healthcare settings such as hospitals.7
