Bangladesh has experienced several outbreaks of dengue fever over the years, particularly during the monsoon and post-monsoon periods when mosquito breeding sites are more prevalent due to increased rainfall and humidity. These outbreaks have often resulted in a significant number of cases and, in severe cases, fatalities. The densely populated urban areas of Bangladesh, especially Dhaka, the capital city, have been particularly susceptible to dengue transmission due to the high population density and inadequate mosquito control measures.

Efforts to control and prevent the spread of dengue fever in Bangladesh have included measures such as:

1. Mosquito Control: Initiatives to eliminate mosquito breeding sites, such as cleaning up stagnant water sources where mosquitoes breed, using larvicides to target mosquito larvae, and insecticide spraying to control adult mosquito populations.
2. Public Awareness: Public health campaigns to educate people about dengue fever, its symptoms, and preventive measures like using mosquito nets, wearing protective clothing, and using mosquito repellents.
3. Healthcare Infrastructure: Strengthening healthcare facilities to provide timely and effective treatment to dengue patients, especially during outbreaks.
4. Surveillance and Reporting: Improved disease surveillance systems to detect outbreaks early, track cases, and respond effectively.
5. Research and Collaboration: Research into mosquito behavior, virus transmission, and potential vaccines, as well as collaboration with international organizations and researchers to benefit from global expertise in dengue control.
