The number of dengue and malaria cases in the city has gone down considerably, said a report prepared by the Kolkata Municipal Corporation.
In 2023, 192 cases of dengue were found in the city till 7 July. A senior civic official said the number of dengue cases dropped by 29 per cent this year. Till 7 July, 136 cases were detected. The number of malaria cases dropped from 1,667 in 2023, till 7 July to 404 in 2025, till 7 July.
This has been possible because of a slew of measures taken by the civic authorities throughout the year, said Debashis Biswas, chief vector control officer and OSD of KMC.
He said a borough-level health administrative meeting taken by the health department is going on. The meetings are attended by the chairpersons, ward councillors and senior officials from the health, engineering, solid waste management department, building and assessment-collection departments. Ward-wise vector management activities and other public health related issues were reviewed in these meetings. The meetings on this subject started on 26 March.
He maintained prompt diagnosis and treatment of malaria throughout 144 ward UPHCs. Test reports are sent to patients through SMS alerts.
The dengue detection centres are kept open on all the six days of the week for testing of dengue NS1 antigen and dengue IgM antibody. Blood samples drawn at UPHCs are brought to these DDCs for undertaking such tests.
There are 930 vector control teams, consisting of one from FW (finance) and one from IEC, who visit the houses and apartments in the city.
The 144 ward vector control in-charges, 16 borough VCIs, 1 senior entomologist and 3 vector control officers monitored vector control activities in fields under the guidance of the OSD & ex-officio chief vector control officer. Such monitoring will continue till December 2025.
