If you have previously been infected with dengue fever, consult with 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.

Dengue fever is a year-round threat in areas of Peru below 2,000 meters elevation; however, transmission is typically highest September-May when environmental conditions are ideal for mosquito breeding. Peru reported roughly 271,733 dengue fever cases nationwide in 2023, 63,168 cases in 2022, 44,791 cases in 2021, and 47,932 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 promptly.
