Jammu, Oct 2: Dengue cases have been rising the past fortnight, with Jammu recording the highest number of cases in the region, officials said. So far this year, over 1,100 cases have been reported across the Jammu region, which is slightly lower than last year, they said. Health officials pointed out that heavy rains and waterlogging have created conditions for mosquito breeding. “There has been an increasing trend of dengue cases in Jammu region,” health department officials said. Jammu is undergoing intense citywide thermal fogging and spraying by the Jammu Municipal Corporation to prevent the spread of vector-borne diseases such as dengue, malaria and chikungunya.
