The health department carried out checks in various areas of the city and found larvae of Aedes egypti mosquito, the vector that transmits the dengue virus, in four houses in Lakshmi Nagar, New Janakpuri, Salem Tabri and Guru Arjun Dev Nagar on Friday.
July is being observed as dengue awareness month by the health department as breeding of the Aedes aegypti mosquito increases in monsoon.
District epidemiologist Dr Anil Verma, who supervised the drive, said: “Checking of coolers and containers was conducted in houses as this mosquito breeds in clean water. The team destroyed the larva found in houses on the spot and information regarding this has been passed on to the municipal corporation to issue challans to the violators.”
Dr Verma said they would continue the drive, which began in mid-June, through July.
This year, 10 dengue cases have been confirmed in the city of which five were from the other districts while remaining were reported from Ludhiana.
