Over 50 dengue cases have been reported in the Uttar Pradesh capital in the past one week, officials said Friday.
Chief Medical Officer S.N.S. Yadav ruled out any major outbreak of the disease. But several private clinics and state-run hospitals say they have admitted many patients with low platelets and dengue symptoms.
A doctor at a nursing home in Mahanagar told IANS: "We have many dengue patients but no data has been collected by the authorities."
The worst affected is the area around the King George's Medical University in Chowk where more than a dozen medical students have taken ill.
Efforts were on to increase fogging in the city, officials said.
