Socio-Environmental Factors Associated with Dengue Fever Prevalence in Central Indian Population: A Cross-Sectional Study

Background and Objectives: Incidence and Prevalence assessment as epidemiologic measures for evaluating the burden of dengue plays a vital role in making management strategies and monitoring disease control progress. Hence, this is an important evaluating factor for evaluating the actual burden. The present trial was aimed at assessing gender and age-specific dengue incidence in the Sasaram Rohtas, cohort with the help of associated factors and prevalence in dengue infection. Methods: The present clinical trial was carried out in 600 subjects of 0-70 years of age. Epidemiologic and laboratory findings were collected from the hospital and the collected data were subjected to statistical evaluation and the results were formulated. Results: There were more females in the present study compared to males. The highest positivity rate in Dengue was seen in the age group of 0 to 9 years. Among 243 adult males, 70 (28.80%) and among 357 adult females, 170 (24.08%) were found to be suffering from dengue infection. Concerning dengue positivity, there were 156 dengue positive cases and 444 dengue negative cases. In age group of 0-2, 2-9, 10-19, 20-29, 30-39, 40-49, 50-59 and 60 years above, there were 14.10% (n=22), 19.87% (n=310, 16.66% (n=26), 14.10% (n=22), 10.25% (n=16), 8.97% (n=14), 10.89% (n=17), and 5.12% (n=8 ) subjects respectively. This shows maximum cases in 0-19 years of age and decreases incidence with increasing age. Conclusion: Within its limitations, the present study concludes that dengue incidence decrease with increasing age. Such studies assessing seroprevalence should be conducted on regular basis to assess a clear picture of the dengue burden in Rohtas, Bihar.
