Dengue infections in Chattogram have risen sharply, with an average of 11 new cases daily. In the first five days of July alone, 57 people were infected, including 18 in a single day. The divisional health director’s office has identified eight city wards as high-risk dengue hotspots, where one in every four houses contained Aedes mosquito larvae. The survey found that 70–80 percent of the larvae were of the Aedes aegypti species, the primary dengue carrier.

Residents have expressed concern over inadequate mosquito control, alleging irregular spraying of insecticides across the city’s 41 wards. In response, the Chattogram City Corporation (CCC) and the district civil surgeon’s office stated that dengue corners have been set up in all government hospitals, with increased test kits and beds. The CCC claimed that spraying is being conducted daily across seven zones with upgraded equipment and additional manpower.

Health officials have urged citizens to destroy mosquito breeding sites at home. The divisional health director confirmed that coordinated action plans are underway to strengthen mosquito control and ensure effective treatment at the upazila level.
