Context

The measles outbreak in Chad has been ongoing since 2018. Officials reported more than 26,600 cases nationwide in 2019, compared to roughly 700 cases in 2018. Measles vaccination coverage is estimated at less than 70 percent, lower than the 92-95 percent recommended to prevent widespread transmission.

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.
