Dengue fever is a nationwide, year-round threat in Colombia, however, transmission is typically highest May-November during and immediately following the rainy season. Colombia reported roughly 131,784 dengue fever cases nationwide in 2023, 69,497 cases in 2022, 53,334 cases in 2021, and 78,979 cases in 2020.
There are two dengue fever vaccines, Dengvaxia and Qdenga. It is only recommended for individuals with a history of dengue infection and in a country with a high dengue fever burden. Dengue fever is transmitted through the bite of an infected mosquito. The risk of infection is often highest in urban and semi-urban areas. Symptoms of dengue fever include a sudden onset of fever and at least one of the following: severe headache, severe pain behind the eyes, muscle and/or joint pain, rash, easy bruising, and/or nose or gum bleeding. Symptoms typically appear 5-7 days after being bitten but can develop up to 10 days after exposure. Dengue fever can progress to a more severe form known as dengue hemorrhagic fever (DHF). DHF can be fatal if it is not recognized and treated in a timely manner.
