Mumbai:The H1N1 virus may be back in circulation but it is actually malaria and dengue that is plaguing Mumbaikars.

According to BMC data, 693 people contracted malaria and 94 were treated for dengue in January. None of the vector-borne ailments claimed any lives. Physicians said it is common to treat at least a couple of malaria cases on a daily basis during this time of the year. But dengue cases should not be rampant now. A senior physician from KEM Hospital said the severity of dengue cases as compared to last year had come down.
