The number of dengue cases in Maharashtra rose 63% between January and October this year compared to the same period last year. The number of deaths have remained the same, with 22 deaths in the comparative periods for 2015 and 2016.
Dengue is transmitted by the aedes aegypti-species of mosquito and has become a major public concern in the past two months, doctors said. A total of 5,653 cases were reported by the state epidemiology department this year as compared to 3,461 cases last year, with cases coming from cities like Mumbai, Kalyan-Dombivli, Pune and Nashik, said Dr Kanchan Jagtap , joint director of health services of the state.
“Every year, there is an increase in the number of dengue cases post monsoon. Moreover, the increase in construction sites have created an ideal environment for mosquito breeding,” she said.
Although the number of dengue cases has gone up, not everyone who is infected with the virus develops complications, said doctors. “Say out of 100 people infected with dengue, only 10 show complications such as a drop in blood pressure, severe drop in n platelet counts, ”said Dr Pradeep Shah, physician, Fortis Hospital, Mulund.
“Most of the patients who show complications are people who have had dengue in the past, young children, elderly and pregnant women. These are the vulnerable groups,” he said.
Doctors also said state data could be giving an incomplete picture of the dengue situation, because only those cases where the patient has tested positive for dengue infection using the ELISA (enzyme-linked immunosorbent assay) method of testing are counted as confirmed. “We treat so many patients who have all symptoms of dengue infection, but their blood test reports for ELISA test are negative. These numbers are not accounted for in the state’s data,” said Dr Altaf Patel, director of medicine Jaslok Hospital.
