Weather helps to reduce dengue cases in New Delhi

New Delhi, Persisting low minimum and maximum temperatures and smog have lent a hand to put a break on the spread of dengue as less number of cases have been reported in the month of November compared to September and October in the national capital New Delhi.

The continuous low temperatures and smog around Diwali have largely stopped the breeding of dengue mosquitoes and as the winter is about to set in, dengue menace would be finally over within a fortnight or so.

Though cases are still being reported but a usual 10-14 days is the incubation period (the time between being exposed to infection and showing first symptoms) for the disease to show up after a person is bitten. So even if smog and change in temperatures have reduced mosquito breeding, cases will continue to be reported for a few more days.

1799 cases of dengue cases have been reported in New Delhi until now including four proving fatal. Dengue mosquito starts breeding just towards the end of the monsoon season as it did this season.
