Result: Out of 979 family members of patients tested, 183 (18.7%) individual showed asymptomatic positive immunological response of dengue virus infection. Respondents who leave in a district have risk to be infected 1.35 fold greater than those who leave in a city (p= 0,043; 95% CI=l, 004-1, 805). There is no significant risk to be infected among gender (female and male respondent) and age groups c: 15 years and> 15 years).
