With unseasonal rain lashing the city, Mumbai doctors warn of a rise in flu and viral cases along with vector-borne diseases like malaria, dengue and chikungunya in coming days. Doctors said they have been witnessing a rise in swine flu and dengue cases and are worried that it will rise in the coming days. 

Dr Kedar Toraskar, critical care specialist, Wockhardt Hospital, said the sudden rainfall in the city has brought air pollution under control but it can be bad news for Mumbaikars prone to allergy rhinitis. “People who have allergy issues can have trouble as it may get bad. The sudden drop in temperature and change in climate can lead to more viral infections. Influenza and swine flu cases also can rise in coming days,” he said.
