Context

Authorities reported 1,451 dengue fever cases in Timor Leste during 2020 and 901 in 2021. The threat of dengue fever infection exists nationwide in Timor-Leste and is highest December-April.

A dengue fever vaccine is available in some countries. It is only recommended for individuals with a history of dengue infection and in a country with high dengue fever burden. Dengue fever transmission happens through the bite of infected mosquitoes. 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 also 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 promptly.

Advice

If you have been previously infected with dengue fever, consult your physician regarding vaccination. Avoid mosquito bites and remove standing water to reduce the number of biting mosquitoes. Seek medical attention if symptoms develop within two weeks of being in affected areas. Do not use aspirin or ibuprofen products if dengue fever is suspected, as these could exacerbate bleeding tendencies associated with the disease.
