The 2006 dengue outbreak in Pakistan was at the time the worst on record. [1] There were 1,931 lab-confirmed cases, and 41 confirmed deaths, according to the World Health Organization Regional Office for the Eastern Mediterranean. [2] Other sources report a death toll of 52. [3] Most of the cases were from the east, center and north of Karachi, the capital city of Sindh. [4]
At the time, dengue was a relatively new public-health challenge in Pakistan. [5] [6] Limited patient-management standards contributed to a higher mortality rate. [7] [8] The principal mosquito vectors - Aedes aegypti and Aedes albopictus - were already recognized, and subsequent studies identified their increasing role in dengue transmission. [5] [8] [9]
