Potential Aedes mosquito breeding grounds have been identified in 69.45% (8,764 out of 12,619) of homes and under construction buildings in areas under Dhaka North City Corporation (DNCC).
The figures emerged after inspections were carried out in 55 wards under the DNCC on Saturday.
The houses were inspected as part of the second phase of the pre-season Aedes survey monitoring activities of 2020.
Following the first phase of the special drive conducted from June 6 to June 15, the second phase of the 10-day drive began on Saturday.
To protect city dwellers from dengue through controlling the spread of Aedes mosquitoes, a year-long mosquito eradication program has been planned under the direction of DNCC Mayor Atiqul Islam.
As many as 12,619 houses were inspected during the monitoring, of which 91 houses were found to have Aedes mosquito larvae and pupae, while potential breeding grounds for the mosquito were observed in 70% of the inspected houses and under construction buildings.
The executive magistrate of the teams imposed fines totalling Tk1.55 lakh under 12 cases filed during the drive. Meanwhile, inhabitants of homes with potential breeding grounds were served warnings.
A team from the National Malaria Elimination and Aedes Transmitted Disease Control Program of the Communicable Disease Control (CDC) unit of the Directorate General of Health Services (DGHS) is directly participating in the monitoring activities along with DNCC.
Six doctors and nine entomologists from the DGHS, three entomologists from the DNCC, along with officials from the health and waste management departments of the DNCC, are directly taking part in these drives.
Most potential Aedes mosquito breeding grounds, larvae and pupae were found in Mohakhali region 3, Mirpur 10 region 4, Mirpur region 2 and Uttara region 1.
An online meeting was called by the DNCC in this regard on Friday, in which all department heads, senior officials and entomologists of the DNCC participated.
The DNCC mayor instructed mobile courts to be stricter during the drives this time around.
The mayor said if the owners of under construction buildings or establishments could not be found, regular cases would be filed against them if required.
Bangladesh experienced a massive dengue outbreak in 2019 when 101,354 people were hospitalized. According to the health authorities, the mosquito-borne disease killed 179 people last year.
