Dengue haemorrhagic fever (DHF) is an acute febrile disease caused by any of the four serotypes of dengue virus (DENV I , DENV 2, DENV 3 and DENV 4), belonging to flaviviruses. It is a public health problem of growing importance in areas where the insect vector, Aedes aegypti mosquitoes are present. A total of I 50 clinically suspected dengue patients were recruited, mean age of the patients was 31 .86+1 .66. The maximum age of the patients was 81 years and minimum age of the patient was 5 years. Out of I 50 patients 24.0% (n=36) were tested negative for any of the four serotype of the Dengue virus. The analysis showed that 45.3% (n=68) patients had DENV2 serotype, 16.7% (n=25) had DENV 3 serotype and 14.0% (n=21) patients were diagnosed to have DENV 4 serotype; none of the 150 patients was reported to have DENV I serotype. The most prevalent serotype was Dengue virus serotype 2 and Dengue virus serotype 4 was observed as lowest, while Dengue virus serotype I was having zero prevalence. Out of 150 patients 58.7% (n=88) were male while 41.3% (n=62) were females. Among the male population 31 were affected by Dengue virus serotype 2, 18 males were Dengue virus serotype 3, and Dengue virus serotype 4 was observed in 18 males while 21 males were reported negative for any of the serotype. In contrast among female population Dengue virus serotype 2 was present in 37 females, Dengue virus serotype 3 was observed in 7 and Dengue virus serotype 4 was fixed in 3 females only; while 15 females were negative for any of the serotype of Dengue virus. The data showed that p-value (p< 0.005) depict the association between gender and serotypes of Dengue fever. Our Research point out the prevalence of three out of four serotypes among the Pakistani population, which is a shocked fact as per pathogenesis theory that second infection by a different serotype may prove fatal for previously recovered person. Therefore a strict mosquito control programme is direly needed to prevent these incoming events to occur, the only hope and solution is in our environment. Moreover masses education regarding dengue fever might prove helpful in preventing zoonoses.
