Dengue has made a comeback in Delhi but with a much milder strain. Although the number of cases has been increasing since the rains stopped a fortnight ago, they are by far very few as compared to the past several years.
"Last year, about 180 cases were reported by this time. This year, there are only 39 officially reported cases, which is about one-sixth of the cases reported in 2011," said Dr NK Yadav, medical health officer, South Delhi Municipal Corporation.
He added that the "cases this year have been the lowest in 10 years."
"We are getting an average of seven positive cases every week since August, which is one a day in a population of the size of Delhi," he said.
Although no comprehensive official database is maintained for diseases across hospitals, including private ones, the approximate figures suggest that the dengue cases have crossed the 400 mark.
But the doctors say that there is no cause for panic this year.
"This year the strain is much milder than previous years when we saw epidemic-like situations in 2008 and in 2010," said Dr Monica Mahajan, senior consultant at Max Hospital, Saket.
The hospital chain has reported over 280 cases this year.
"We can't even peg critical cases at 1 in 10," she said.
Dr RK Singal, head of internal medicine at BL Kapoor super speciality hospital at Pusa Road feels that that the severity of disease is not that potent.
"The strain is not virulent and cases are not many. Even today, we saw only six cases of dengue and none of them required any major blood transfusion," he said.
The hospital has received over 50 cases of dengue this season.
