Dengue cases fail to drop in Pune

Even as the winter is slowly settling in the city, the cases of dengue have failed to reduce substantially. In December alone a total of 242 cases of suspected dengue have been registered with the Pune Municipal Corporation (PMC).

Experts say that when the temperatures fall below the standard of 16 degrees, it becomes very difficult for the dengue mosquitoes to breed. Hence, very rare transmissions have been observed during the winter season.

The health department is seen struggling in its efforts to prevent increase in dengue mosquito breeding grounds.

As per the data available with the insect control department at PMC, a total of 41,489 dengue breeding grounds have been found by the department since June 19 this year. The officials said that all these sites were treated with insecticides to prevent breeding of these mosquitoes.

“Dengue mosquitoes breed in fresh water which is left stagnated for a week. The recent rains may have also led to rise in mosquito breeding spots,” said officials from PMC.

According to the health department, presently there are 6,157 cases of suspected dengue registered with PMC this year out of which 1,627 have been confirmed. The city has also seen five deaths due to dengue so far.

According to the officials at the department, under the insect-borne diseases control programme, the department has collected a fine of Rs.4,12,903 so far from property owners who have neglected their premises and mosquito breeding was ascertained in these areas by PMC workers.

According to the data furnished by the health department, Yerawada, Kalas and Dhanori are the areas with maximum dengue cases. Kasba peth, Vishrambaug, Bhavani peth and Dhole Patil road ward offices were the other prominent areas where maximum number of dengue sites were found by the insect control department of the PMC health department.

Kalpana Baliwant, head of the insect control department at PMC said, “The department is taking several measures to prevent dengue mosquito breeding. It must be understood that a female adult mosquito lays a total of 450 eggs in her lifetime. If she is infected with dengue then all the eggs she lays are also infected with dengue. Hence, eliminating these infected adult mosquitoes is important for which fogging is very efficient.”

Alarming figure

Cases of suspected dengue- 6,157

Confirmed cases - 1,627

Confirmed cases in December - 82

Confirmed cases in November - 448

Deaths– 5

Cause and effect

Dengue is transmitted by the bite of the Aedes mosquito that mostly attacks during day time. Its favourite spots are below the elbow and below the knee. Dengue mosquitoes can’t breed once the temperature falls below 16 degree. Till now there is no vaccine to protect against dengue. Dengue cannot be transmitted from person to person without a mosquito as the intermediate vector.
