West Bengal Names Five Dengue Hotspots Amid Intensifying Monsoon
West Bengal has identified five districts where dengue is a particular concern.
They are Kolkata, Howrah, North 24 Parganas, South 24 Parganas and Murshidabad.
Dengue is spread by mosquitoes, which can breed in standing water.
Heavy rain can leave water in pots, containers, rooftops and other places.
The state had recorded 4,035 dengue cases by August 19.
Seven deaths were officially linked to dengue, while officials counted 10 when other seriously ill patients were included.
Government departments and municipalities are increasing inspections and mosquito-control work.
Kolkata Municipal Corporation and Metro Railway are also checking Metro stations and nearby areas.
Residents are being asked to remove standing water and keep their surroundings clean.
Kolkata, Howrah, North 24 Parganas, South 24 Parganas and Murshidabad were identified as West Bengal’s most dengue-prone districts.
West Bengal recorded 4,035 dengue cases by August 19, with seven officially attributed deaths and 10 deaths including patients with other serious conditions.
The state reported 15% fewer dengue cases than during the corresponding period last year as of August 16, officials said.
Authorities ordered expanded surveillance, cleanliness drives and mosquito-breeding-site inspections, including at government buildings and Metro stations.
Officials urged residents to remove stagnant water and cooperate with civic workers as continued monsoon rainfall could create new breeding sites.
