The 12 response teams, each comprising an entomologist, three-four field workers and two assistant malaria inspectors, will visit different zones of the city to detect mosquito breeding and if found, it will take immediate measures to prevent it from spreading, a senior MCD official said.
The teams have been set up to look into deficiencies and to contain mosquitoes, he said.
The MCD has decided that the domestic breeding checkers, who undertake house-to-house surveys to prevent mosquito breeding, will also start work on April 1, much ahead of the monsoon season.
The hastened steps from MCD come close on the heels of the first report of dengue fever in the city after a doctor at AIIMS was diagnosed with the virus earlier this month.
Much against the normal belief that dengue cases decrease during winters, the MCD is worried as a number of dengue cases reported from various parts of the city during winter months.
"The epidemiology of dengue is changing. Winters or early summers are not the conducive seasons for aedes mosquitos' breeding, still then dengue fever cases are being reported from hospitals. We have to be prepared to control any outbreak," the MCD official said.
Last year, the first dengue case was reported in June and 6,229 patients were infected with the virus -- a jump of over 400 per cent over the figures of 2009 when the number of cases was 1,153 only.
