The mosquito-borne infection has gripped the city since June and more cases are being reported from Warje, Hadapsar, Kothrud, Tilak Road, Karvenagar and Aundh. Residents of Dhole Patil Road, Ahmednagar Road, Sangamwadi, Bhavani Peth, Vishrambaugwada, Bibvewadi, Sahakarnagar and Dhankawdi have also been affected.
As far as virulence of different serotypes is considered, it is believed that DENV-2 is associated more often with dengue haemorrhagic fever that occurs in secondary infections.
There were 36 confirmed cases of dengue in Pune city in June. It rose to 44 in July and 99 in August, he added.
Climatic conditions favourable for breeding of mosquitoes, increased storage of water, increasing construction activity, piling of garbage, lack of public awareness about the measures that need to be taken has aggravated the situation. Since Aedes aegypti, the mosquito which spreads dengue breeds in fresh water, it is imperative for every household to empty and clean all utensils and tanks at least once a week.
The number of reported dengue cases has gone up considerably ever since the PMC’s health department started collating data from private hospitals this year. Earlier, the PMC would collect data only from the government-run Sassoon General Hospital and the civic hospitals.
