With 804 fresh cases of dengue reported in the national Capital last week, the total number of patients who contracted the infection during the season has reached  4,205, according to the latest report released by South Delhi Municipal Corporation (SDMC). However, the number of cases reported last year until November was much more at a staggering 7,358.

The report also stated that 20 new cases of malaria have also been reported, taking the total number of cases to 847 this year. According to the report mosquitoes breeding has been reported in nearly 221319 households in the national Capital this year till November 3, according to the data released by all three corporations, which are grappling with rising number of cases of the vector-borne diseases. Among the areas falling under the three municipal corporations, the cases of breeding reported were - NMC (69287), SDMC (91611) and EDMC (60421).

As per the report, all three corporations have issued 177174 legal notices to various people and establishments after mosquitogenic conditions were found in their houses or premises. At least 25211 prosecutions have also been launched after breeding was found, the report said.

According to municipal health officials, most of the breeding detected in waste products left in open.

Domestic breeding of mosquitoes is one of the main reasons responsible for people contracting these diseases, he said.

Concerned over sporadic reports of vector-borne diseases, civic bodies had issued an advisory on prevention and control of vector-borne diseases and called for prevention of breeding at the source and made it clear that taking precaution is the only effective tool for prevention and control of these diseases.

A senior SDMC official said that the civic body has been campaigning to aware people for not allowing stagnation of water in their surroundings.

Dengue and chikungunya are caused by the bite of Aedes agypti mosquito, which breeds in clear water, while Anopheles mosquito, which causes malaria, can breed in both fresh and muddy water. In one of the worst outbreak, a total of 12,221 chikungunya cases were reported in Delhi till December 24, 2016, out of which 9,749 were confirmed.
