The number of dengue cases in the city more than doubled between 2012 and 2013 while the cases of malaria dropped marginally. According to the anti-malaria headquarters of the civic agency, the city recorded four dengue-related deaths in 2012 and six in 2013.
In 2013, Delhi recorded more than 1,900 cases of dengue in September and over 2,400 in October. The corresponding figure for cases of malaria in the same months is 62 and 51 respectively. As many as 200 cases of malaria were recorded last year, down from 246 in 2012.
However, despite the increase in both the number of cases and deaths, the civic body issued 113 legal notices to houses with mosquitogenic conditions as against 1,415 in 2012. Number of houses sprayed was also reduced from more than 2,800 in 2012 to 1,788 last year.
The number of house visits was increased exponentially to check domestic breeding. South corporation Municipal Health Officer Dr NK Yadav said, “The number of houses sprayed has been reduced to the use of vehicle mounted spraying machines last year. We earlier used handheld machines but they covered lesser area.”
Yadav said reporting of cases has also been increased by hospitals. “When we increase reporting of cases further, we will decided on containment measures for the future,” he said.
Spokesperson for the North and East corporations Yogendra Mann said the increase in the number of dengue related cases in the city was the result of intermittent rains and consistent humid conditions. “In every three to four years, the number of cases reaches its peak,” Mann said.
