Facing criticism, Chief Minister Arvind Kejriwal sought cooperation from Opposition parties to deal with the situation.
The latest dengue victim Rishabh, a resident of New Seemapuri in north-east Delhi and a class 10 student, died at Max super-speciality hospital in Ghaziabad and his family alleged medical negligence and claimed they were charged exorbitant fees by the hospital.
Chief Minister Kejriwal inspected two East Delhi hospitals to take stock of dengue preparedness at a time when more than 2,000 people are in the grip of the disease.
Kejriwal made rounds of Lal Bahadur Shastri Hospital and Rajiv Gandhi Super Speciality Hospital. He opened 200 beds at the latter as part of the government's move to add 1,000 similar beds by Sunday.
The Chief Minister, who interacted with patients, doctors and hospital staff during his visits, also lashed out at the BJP-ruled civic bodies for their alleged financial misappropriation and lack of efforts to contain the disease.
"Whatever amount you give them, they siphon off each and every penny. More than work, money is paramount for them. They are not satisfied no matter how much you give them," he told reporters responding to allegations that the government had not released enough funds to the corporations.
