Chennai Intensifies Mosquito Control Amid Rising September Dengue Cases
Chennai is working harder to stop mosquitoes from spreading dengue.
The city has reported more than 650 dengue cases in September so far.
The Greater Chennai Corporation sent 3,597 workers to inspect homes and other buildings.
Each worker checks about 80 to 100 households every day.
They remove things such as old tires, coconut shells, and broken containers where mosquitoes can breed.
Chemicals are used in water tanks, canals, and drains to kill mosquito larvae.
Workers also use fogging to reduce adult mosquitoes.
Doctors and health workers were trained to manage fever, and some patients are watched after leaving care.
The Greater Chennai Corporation deployed 3,597 workers across all 15 zones for mosquito and dengue control.
More than 650 dengue cases were reported in Chennai during September so far.
