In Bangladesh's ongoing 2023 dengue epidemic season, the country has been witnessing the deadliest outbreak of
In June 2023, the Institute of Epidemiology, Disease Control and Research (IEDCR) reported that people are getting affected with the DENV-2 and DENV-3 variants this season, the two with the highest rates of infections and death.[8] In 2022 and 2021, DENV-4 and DENV-3 were found for the first time, respectively.[9][10] Although a patient does develop immunity to a certain variant after being infected with it, cross-infection with different variants raises the chance of complications and mortality. Secondary infections show changed symptoms, thus delayed hospitalizations are causing more deaths. It's notable that the death rate has more or less increased in Bangladesh in past years.[11] With more severe cases being referred to the capital, Dhaka's hospitals struggle to control the situation.
Outbreak Background
According to the
Bangladesh has also experienced several smaller spread Dengue outbreaks with a notable outbreak in 2000 infecting 5,551 individuals and resulting in the deaths of 93. Since 2017 the most common form of Dengue has been DEN-3, and according to the Bangladesh Medical Research Council from 20 to 19 indicated an increase in the density of mosquitos in and around Dhaka in the "monsoon survey (18-27 July 2019) of 100 sites of 98 wards in Dhaka city both North and South revealed that the number of adult aedes mosquito was increased by 13.52 folds, in compare to the pre-monsoon (3-12 March 2019) survey."[14]
Bangladesh is a nation particularly vulnerable to Dengue Fever due to the warm climate and heavy rainfall, enabling the fever to spread through Aedes aegypti and Aedes albopictus mosquitoes which are described by the UN as "long plagued tropical and sub-tropical regions".[12][15] ACAPS noted in a briefing note that "Dengue outbreaks usually coincide with the warmer months and monsoon season" which for Bangladesh is typically between May and September. ACAPS also noted that poor urban planning for water and waste allowed water to sit in dense areas, allowing mosquitoes to have ease of spreading and reaching humans.[16]
