There has been a drastic drop in the number of dengue cases this year, according to data available with civic agencies, but health experts warn people against dropping the guard.
While 60 people were diagnosed with the fatal mosquito-borne disease in 2011, civic agencies have reported 11 cases this year.
"The numbers are not very high this year. I get no more than one or two cases a month, that too of very mild strain. There have been no hospitalisations and almost all patients recovered at home," said SP Byotra, chairman, department of medicine, Sir Ganga Ram Hospital.
The doctor, however, added that because there has been only a week of heavy rain this year, the threat of dengue is still far from gone.
"The water is still flowing, and mosquitoes usually breed in stagnant water. There is a possibility of the number rising in a few weeks," he added.
The data from some prominent private hospitals in the city - Fortis Hospital, Vasant Kunj, Fortis Hospital, Shalimar Bagh, Sir Ganga Ram Hospital and Indraprastha Apollo - reveals that since January, 14 persons have tested positive for dengue, though none was critically ill.
"We do not count patients who are not from Delhi. Private hospitals often get patients from places in the National Capital Region which are not in Delhi," said NK Yadav, health officer, department of public health, unified Municipal Corporation of Delhi.
There has been a year-on-year increase, however, in the number of malaria cases. According to official figures, 132 cases of malaria have been reported in the city in 2012. Last year, 108 cases were reported. Six persons have tested positive for chikungunya and there has been no Japanese encephalitis cases reported so far.
"The number of malaria cases could be higher because we added more laboratories this year and have further intensified disease surveillance," added Yadav.
"Protection from mosquitoes is the best way to keep away from the disease. Do not let water collect inside or outside your residential or work premises. Use a mosquito repellent. Wearing full-sleeved clothes is advisable," said Dr AB Dey, professor, department of medicine, All India Institute of Medical Sciences.
"Avoid painkillers if you have high fever with body ache as most of them tend to lower the platelet count which could be fatal in cases of dengue," added Dr Dey.
