Two months’ data of Dengue disease patients from 14 Sep 2011 to 15 Nov 2011, who visited Lady Reading Hospital, Khyber Teaching Hospital & Hayat Abad Medical Complex for diagnosis. An informative Questionnaire was designed for data collection from mentioned hospitals. In LRH, 140 Dengue patients were recorded, in which 93.57% were male and 6.42% were female, of which the recorded mortality were 1.42%. In age wise prevalence, the people most affected fall in the age group of 21-30 years, which is 44.28% of the total population. In KTH, a total of 85 individuals were tested for Dengue fever with 56.64% positive cases, 14.11% negative and 28.23% were suspected. In gender wise prevalence the people more affected were 48.23% males and 9.11% females. The same age group was severely affected by dengue virus with 42.35% of the total population. In HMC, 363 individuals were examined in which 20.11% were positive and 79.88% were negative. In gender wise prevalence the people more affected were 68.87% male and 21.12% were females. The present research study will provide reports and recommendations to the concerned field and will make awareness of Dengue Disease among patients and the public of KPK for their safety. Moreover, same study should be conducted in large population size to determine the other risk factors. Keywords: Aedes aegypti, LRH, KTH, HMC, dengue & Prevalence 1. Introduction Dengue fever causes 50 million infections and 20,000 deaths worldwide each year [1] . Aedes aegypti mosquitoes are amongst the anthropophagic insects because they feed on human blood. Adult Aedes aegypti mosquito is the best known primary vector of dengue fever. Dengue infection is caused by any of four distinct serotypes of virus viz. DEN-I, DEN-II, DEN-III and DEN-IV [2] . Aedes aegypti is tropical and subtropical specie which cause a huge medical and financial burden by spreading Dengue fever, Yellow fever, Chikungunya and Zika virus [3] . Aedes aegypti transmits the dengue virus to humans through blood-feeding of an infected person. Later, that virus is transmitted to non-infected person. The adult female Aedes aegypti are the vectors of dengue fever exclusively [3] . Humans are not directly infected by male Aedes aegypti mosquitoes although; they play a significant part in the transmission cycle [4] . 1.1 Morphology of Aedes aegypti The morphology of Aedes aegypti body parts of head, neck, thorax and abdomen like mouth brush, spines, compound eye, antenna, comb spines, siphon tube, pectin teeth and anal papilla are described by various researchers. The antennae of adult Aedes aegypti are smooth and cylindrical in shape. It has a single hair [5] . Aedes aegypti adults have white scales that form the shape of a violin, on the dorsal (top) surface of the thorax. The abdomen is generally dark brown or black which may possess white scales [6] . Female Aedes aegypti are larger than males. Males have plumose antennae which is dense while females have less dense pylose antennae (sparse short hairs). Male Aedes aegypti mosquito mouthparts are modified for nectar feeding, and female Aedes aegypti mouthparts are modified for blood feeding. The proboscis of both sexes is dark [7] .
