PREVALENCE AND ASSOCIATED FACTORS OF DENGUE INFECTION AMONG BHILAI POPULATION: A HOSPITAL BASED CROSS SECTIONAL STUDY

Abstract

Background: Epidemiologic measures of the dengue burden such as prevalence and incidence are important for policy-making and monitoring the progress of disease control. In this study, we estimated the trend of dengue incidence and hospitalization in a secondary hospital.

Objective: The age and gender specific incidence of dengue between the periods of January 2018 to December 2018 was estimated using the prevalence and associated factors in dengue infection.

Methods: This prospective observational study was carried out in the hospital, over a period of 11 months from January 2018 to December 2018. The study included 1200 determinations of fever between 0-70 years age group. We collected epidemiological data (age and gender) and laboratory data from the hospital database of patients who attended outpatient clinics in the above period.

Results: This study demonstrated female predominance with 45:55 i.e. male: female ratio, overall above findings revealed Dengue positivity was highest in 0-9 year age group i.e. 34.95% and lowest in 60 year and above age group i.e. 5.18%.

Conclusion:  The age-specific incidence of dengue decreased steadily with decreasing by age>70 years. Sero-prevalence studies with representative samples should be conducted regularly to allow better estimation of dengue burden in India.
