There is a new species of dengue-carrying mosquito, Aedes albopictus — also known as the Asian tiger — behind the recent spike in dengue cases in the Capital.
While making this announcement on Tuesday, the three municipal corporations of Delhi said unlike the common Aedes aegypti mosquito that breeds inside homes, this one breeds in open spaces such as parks and gardens.
So far, 1,249 cases of dengue have been reported by the municipalities, including Tuesday’s 38 new cases.
The third dengue death that HT reported on November 2 of an 11-year-old girl from Bhagwan Mahavir Hospital was also confirmed on Tuesday.
“Not much is known about the new species, but it has been found to be carrying the dengue-causing virus. The mosquitoes breed in the open and were first identified in southern India,” said NK Yadav, municipal health officer of south Delhi, who is handling the mosquito control programme of all three corporations.
“The municipal corporations have been carrying out operations to control just the aegypti mosquitoes, but now action has to be taken against the new species as well,” he added.
According to officials, the new species is resistant to traditional forms of mosquito control such as fumigation and spray, and experiments are on to find a more effective way of controlling it.
