A severe viral disease called yellow fever is spreading in parts of South America. This disease is spread through mosquito bites and can cause symptoms such as fever, chills, and muscle aches. The best protection against yellow fever is the yellow fever vaccine, which should be given at least 10 days before travel.
According to the CDC, an increased number of cases have been reported in Bolivia, Colombia, and Peru. Travelers to these newly affected areas are now recommended to get vaccinated. Certain travelers may need a booster dose if they received their last dose more than 10 years ago.
To prevent mosquito bites, travelers should take steps such as getting vaccinated at least 10 days before travel and using insect repellents. If symptoms occur during or after travel, seek medical care immediately. The CDC provides health information for travelers to specific countries in South America, as well as guidance for healthcare professionals and clinicians.
Key points include increased cases of yellow fever, the importance of vaccination, and prevention measures against mosquito bites.
