A total of 40 dengue cases have been reported in Delhi till July 25 this year. Last year during the same period 16 dengue cases were reported.
More than 20 cases were reported in July with 11 patients diagnosed with fever last week alone. But no deaths have been reported so far. Of the 11 cases, five are children between the ages of 3 and 10 said the officials.
The patients are being treated at the Kalawati Saran Children's Hospital in Lady Hardinge Medical College, Baba Saheb Ambedkar Hospital in Rohini, All India Institute of Medical Sciences, Ram Manohar Lohia Hospital and Safdarjung Hospital, among others, the officials added.
According to the officials, only six dengue cases were recorded by the hospital in the month of June. In July, the number of cases increased to 23 last week.
The maximum number of cases were reported from North Delhi (15), East Delhi reported the lowest (8). South Delhi Municipal Corporation has reported 12 cases.
Apart from dengue, 13 patients have been diagnosed with malaria this year, five of them tested positive this month.
The Municipal officials attributed the rise in the number of dengue cases to the intermittent rains this month. Mosquito-breeding spots have been identified in nearly 70,000 houses in the capital.
A municipal official said, "Every year when it rains, the cases go up and subside as the rains stop. This year, we took measures to prevent mosquito breeding much before the onset of the monsoon. Our teams are visiting offices, hospitals and colleges to identify breeding spots."
The Directorate of Health Services under the Delhi government has issued a series of orders to hospitals to deal with dengue patients.
Hospitals have been directed to strengthen laboratories for diagnosis of vector-borne diseases and set up dedicated fever wards.
Following the rise in cases of dengue, Union Health Minister J P Nadda has issued directions to the Central Government hospitals in the capital.
