Bangladesh Records 1,147 New Dengue Cases in 24 Hours

Dhaka, Nov 4: Bangladesh has reported 1,147 new dengue cases and five deaths in the past 24 hours, according to the Ministry of Health.

So far in November, 2,960 dengue cases have been recorded, bringing the total number of infections this year to 72,822 and the death toll to 288.

Dengue, which usually spreads during the monsoon season, is now persisting beyond its typical June-September period, according to Xinhua news agency.

The World Health Organization (WHO) stated that dengue is a viral infection transmitted through the bites of infected Aedes aegypti and Aedes albopictus mosquitoes. The disease is common in tropical and sub-tropical regions, especially in urban and semi-urban areas.

Although there is no specific treatment for dengue, early diagnosis, detection of warning signs, and proper case management can reduce fatality rates to below 1%.

Dengue was first reported in the 1960s in what was then East Pakistan (now Bangladesh) and was called “Dacca fever.” Since 2010, cases have coincided with the rainy season from May to September. Climate change — with increased rainfall, flooding, and rising temperatures — has made conditions more favorable for dengue transmission and other mosquito-borne diseases like malaria and chikungunya.

All four serotypes of the dengue virus have been found in Bangladesh. Until 2016, DENV1 and DENV2 were dominant; in 2019, DENV3 became the leading type, while in 2025, DENV2 has reemerged as the predominant strain.
