Colombia/Brazil: Measles outbreaks amid influx of Venezuelan refugees
Health officials warn of measles outbreaks in Colombia and Brazil amid influx of Venezuelan refugees; ensure measles vaccinations are up to date
Event
Health officials in Colombia and Brazil are on alert as of mid-March due to fears of measles outbreaks amid an influx of Venezuelan refugees. Colombian health officials have confirmed the first measles case in the country since 2015; the case reportedly involved a 14-month old Venezuelan child who was diagnosed with the disease in Medellín on March 13. In addition, according to Brazilian authorities, 50 suspected measles cases, including 14 confirmed cases, have been reported in Boa Vista and Pacaraima (Roraima state) as of March 12. Enhanced public health measures, including vaccination campaigns, have been implemented in Brazil and Colombia to stem the spread of the disease.
Context
According to humanitarian officials, an estimated 500,000 Venezuelans have fled the country since the beginning of the year, with a large percentage taking refuge in Colombia and Brazil. The migrant crisis is expected to worsen throughout 2018 as Venezuela's economy continues to falter.
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
Potentially affected individuals 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.
