The total numbers of dengue cases have reached 26 this year, according to a data released by the South Delhi Municipal Corporation (SDMC) on Monday. On the other hand, the total number of people affected by malaria stood at seven while that of chikungunya at 10.
Breeding of mosquitoes has been reported in nearly 4,571 households in the national Capital this year till April 7, according to the civic bodies, which are grappling with rising number of cases of the vector-borne diseases the cases of breeding reported were - NMC (1,041), SDMC (3,307) and EDMC (223). During the corresponding period last year, breeding was recorded at 5,485 households.
Municipal corporations have issued 7,077 legal notices to various people and establishments after mosquitogenic conditions were found in their houses or premises. At least 467prosecutions have also been launched after breeding were found, the report said.
In order to curb the menace of vector-borne diseases, the civic bodies have already decided to spray insecticide named 'Alpha Cyper Methrin' which remains effective for three months from the date of spraying, an SDMC official said.
Besides, the civic body has also taken a number of measures to prevent mosquito breeding, including creating awareness by using various media, deploying more dengue breeding checkers, and desilting of drains, the official said.
A senior SDMC official said the spraying will be done during months of May and June in the first phase whereas, under the second phase, it will be sprayed in July and August. “The spray will be especially concentrated in JJ and rehabilitation colonies as these areas are very suitable for breeding,” he said.
With the move, the SDMC officials believe that the approaching menace of vector-borne diseases can be checked as the mosquitoes will be paralysed after coming in contact with such insecticide. Indoor residual spraying (IRS) with insecticides is the main vector control strategy adopted in the National Vector-Borne Disease Control Programme (NVBDCP) in India to control malaria transmission.
The total number of the people affected by dengue was 9,271in 2017 and the numbers of malaria and chikungunya cases recorded in 2017 stood at 1,142 and 940 respectively. Of the 9,271 dengue cases, 4,726 patients were from Delhi, while 4,545 had come to the city from other states for treatment.
