Event

Authorities in Bangladesh report elevated dengue fever activity nationwide, with more than 52,800 cases reported Jan. 1-Nov. 20. This is compared to 28,429 cases reported over a similar period in 2021. All eight divisions in the country are reporting cases. Dhaka (34,071 cases) is the most affected division, followed by Chattogram (6,970 cases), and Khulna (2,904 cases). This represents the most complete information available as of Dec. 1.

Context

The risk of dengue fever transmission in Bangladesh exists nationwide and year-round; however, the risk is highest during the rainy season, which typically occurs June-September. 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
