Seropositivity and pattern of dengue infection in Dhaka city.
Bangladesh is experiencing resurgence of' dengue endemic since 2000. In an attempt to see the pattern of' dengue infection we analyzed retrospectively results of 225 blood samples from patients having fever and clinically suspected to have been suffering from dengue fever who were tested for dengue IgM and IgG in Health Care Development Project (HCDP), Dhaka, an enterprise of Diabetic Association of Bangladesh (DAB) one of the largest private health care facility provider in Bangladesh. Out of 225 samples tested, a total of 156(69.33%) cases were serologically positive for dengue and 69(30.67%) were negative. Of the positive cases, 70(44.87%) were positive for Dengue IgM and 86(55.13%) were positive for Dengue IgG. which showed statistical difference between male and female (p<0.05). Both IgM and IgG, were positive in 23(14, 74%) cases. The mean age +/-SD of affected is 36.86+/-17.60 years and the maximum number of positive cases 114(73.08%) diagnosed were in the months between July-December. It is evident from the present study that dengue is endemic in Dhaka city particularly during monsoon and rainy season. Secondary dengue is more common than primary dengue and both preventive and curative measures are needed to combat this menace.
