A recent study by the Brihanmumbai Municipal Corporation (BMC), following a spurt in dengue cases in Mumbai, has highlighted the fact that a large number of mosquito larvae breed even inside the houses of people living in posh localities or apartments.
The survey up to October 20 showed that the city had 1,847 indoor and outdoor breeding sites in Mumbai.
Among the hotspots, where the largest number of mosquitoes breed in the city in South Mumbai, is Ward C of Marine Drive and Chandanwadi areas. A civic official said, “All the 123 breeding sites (in Ward C) were found outside apartments and housing societies.”
Ward G-south of Worli has recorded up to 138 breeding sites. “Of these, 80 were inside and outside residential buildings in non-slum areas. Residents have to ensure that water does not stagnate in their localities and inside their houses, particularly in plant trays, AC ducts, ornamental plants and the like,” said Manisha Mhaiskar, additional commissioner (health), BMC.
Ninety-two breeding sites were found in Byculla of which 69 were in residential areas. Of the 69, 56 were indoors.
In the suburbs, wards M-east (Chembur), N (Ghatkopar) and T (Mulund) are the worst affected.
“While in Chembur there are 110 breeding spots, in Ghatkopar there are 129 and Mulund has up to 246. Up to 50% of these spots are inside people’s homes in housing societies. This is definitely a cause for worry,” said Mhaiskar.
A three-member team of experts Dr Kalpana Baruah, nodal officer at National Vector Borne Disease Control Programme, a scientist from National Institute of Malaria Research in Goa and an entomologist in the state health department is taking stock of Mumbai’s dengue outbreak.
Executive health officer, BMC, Arun Bamne said, “The team visited areas of Byculla, Kamathipura and Madanpura and later analysed in detail vector-borne control measures initiated by the BMC.”
About the disease
Dengue is a viral disease with four strains (DEN V1, V2, V3 and V4) spread by the bite of aedes aegypti mosquito that bites during the day
Symptoms are high-grade fever, headache, pain around eye orbits, body ache and joint pain, nausea, vomiting and skin rash. On experiencing any of these symptoms, visit a doctor at the earliest
Breeding of mosquito larvae occurs in stagnant fresh water
Empty petri dishes below planters, ornamental containers, feng shui articles, money plants, flower vases, water drums, fish tanks, air-conditioning ducts and trays, bird baths and defrost trays of refrigerators to prevent stagnation of water that leads to breeding of mosquito larvae.
