Elevated dengue fever activity reported nationwide in the Philippines through February. Avoid mosquito bites.
Event
Health authorities have reported elevated dengue fever activity nationwide in the Philippines, with more than 17,130 cases reported Jan. 1-Feb. 18. This is 2 times higher than the 8,491 cases reported over a similar period in 2022. The National Capital Region (2,609 cases) is the most affected region, followed by Central Luzon (2,024 cases), Calabarzon (1,704 cases), Northern Mindanao (1,620 cases), and Davao (1,603 cases). This represents the most complete information available as of Mar. 6.
Context
Dengue fever is endemic in the Philippines, and the risk of transmission is highest during and immediately following the rainy season, which typically occurs May-November. Authorities reported roughly 226,497 cases of dengue fever in the Philippines in 2022, roughly 78,208 cases in 2021, and roughly 90,135 cases in 2020.
A dengue fever vaccine is available in some countries. It is only recommended for individuals with a history of dengue infection and in countries with high dengue fever burdens. Dengue fever is transmitted through the bite of an infected mosquito. Symptoms of dengue fever include a sudden onset of fever and at least one of the following: a severe headache, severe pain behind the eyes, muscle and 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.
