Although the monsoon rains have come late this year, the dengue outbreak in Lahore appears to have been controlled. Around this time last year, the city was gripped by fear with people largely staying indoors in the evening and each home reeking of the fumes of mosquito repellents. Dengue, which is usually not fatal unless you are bitten twice in the same season, is spread by the Aedes Aegypti mosquito, a day-biting insect that feeds on human blood.
The outbreak of dengue seems to have a link with climate change. http://dawn.com/2012/09/30/earthly-matters-dengue-under-control/
