Event

Filipino health officials have reported elevated dengue fever activity nationwide, with 51,622 dengue fever cases recorded Jan. 1- June 18.

This report represents the most complete information available as of July 5.

Context

Dengue fever is endemic to the region, and the risk of transmission is highest during and immediately following the rainy season, which typically occurs May-November. Authorities reported roughly 78,208 cases of dengue fever in the Philippines in 2021, roughly 90,135 cases in 2020, and roughly 420,453 cases in 2019.

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 spreads through the bite of an infected mosquito. 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.

Advice

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.
