Madagascar: Measles outbreak continues nationwide /update 3

Event

According to the Ministry of Public Health, at least 15,049 confirmed or suspected cases of measles had been reported nationwide as of late December. Cases have been reported in at least 20 of the country's 22 regions. The most affected areas include Antananarivo (with 8869 cases) and Ambato Boeny (947 cases).

Context

On November 28, the US Centers for Disease Control and Prevention issued a level 1 travel health notice for Madagascar, advising all travelers to ensure they are vaccinated against measles.

Measles is a highly contagious viral disease that typically affects mostly children. It is transmitted via droplets from the nose, mouth, or throat of infected persons. Symptoms of measles are usually a high fever, which begins approximately ten to 12 days after exposure to the virus and lasts four to seven days. A runny nose, a cough, red and watery eyes, and small white spots inside the cheeks can develop in the initial stage. After several days, a rash erupts, usually on the face and upper neck. Over the course of about three days, the rash spreads, eventually reaching the hands and feet. The rash lasts for five to six days and then fades. On average, the rash occurs 14 days after exposure to the virus (within a range of seven to 18 days). A vaccine is available.

Advice

Individuals in Madagascar, particularly in Antananarivo, are advised to ensure their measles vaccination is up to date (including booster shots) and to contact their doctor with any questions or concerns. Anyone experiencing the above symptoms is urged to seek immediate medical attention.
