Angola: Elevated measles activity reported in multiple areas in October

Event

Angolan health officials have reported elevated measles activity in multiple areas, with more than 2,000 cases reported Oct. 1-31. Over a similar period in 2021, there were only 241 cases reported. Bie, Cabinda, Cuanza Norte, Huambo, Luanda, Uige, and Zaire are the most at-risk provinces. This report represents the most complete data available as of Nov. 4.

Context

Measles vaccination coverage in Angola was estimated at 80 percent in 2019 and 44 percent in 2020, much lower than the 92-95 percent required to prevent wider community transmission. Vaccination coverage for 2021 is unavailable. The last notable measles outbreak in Angola was in 2019 when 3,127 cases were reported.

Measles is a very contagious viral disease that spreads through respiratory droplets created when an infected individual coughs, sneezes, or speaks. Infected individuals can also expose people around them by contaminating surfaces with secretions from the nose, mouth, and throat. Symptoms typically appear 7-14 days after exposure, but can develop up to 21 days after exposure. Symptoms generally include fever, cough, runny nose, red eyes, and a red rash that begins on the face and spreads downward. Serious complications - including pneumonia - can occur, especially in children younger than five years old, adults older than 20 years old, and individuals with a weakened immune system.

Advice

Visit a doctor to ensure vaccination against measles or immunity through previous infection. Practice basic health precautions. Call your medical provider if symptoms develop within three weeks of being in affected areas.
