Senior officials of the Delhi health ministry Saturday inspected the worst affected areas of the city, close to the Yamuna river, to ascertain the possible cause of the rising dengue menace.
"We found that most of the cases being reported now are from colonies close to Yamuna river," said D.S. Negi, Delhi's health secretary. He added that of the 95 cases reported in the past 24-hours, over 40 cases were from the central zone, near the river.

The number of dengue cases at AIIMS also saw an increase as 39 new patients were admitted even as 34 were discharged Saturday.
"We are providing treatment to 165 patients in total," said D.K. Sharma, medical superintendent of AIIMS.
