Paradigm Shift in Socio-Demographic Profile of Dengue Infection: A Hospital Based Cross-Sectional Study

BACKGROUND: Dengue is the most rapidly spreading mosquito borne viral disease in the world with increasing geographical expansion to new countries and from urban to rural settings due to combination of urbanisation, population growth, increased international travel and trade and global warming. The epidemiology of dengue fever in India has been very complex with a seasonal pattern. The first outbreak in Odisha was in 2010 and is now spreading to different districts of the state. MATERIALS AND METHODS: A hospital based cross-sectional study was carried out between 2017 to 2018 in the dengue ward of a teaching hospital in Berhampur, Ganjam district of Odisha. RESULTS: The prevalence of admitted dengue patients was 4.32%. Majority of the patients were males (81.9%) and ≥15 years old (91.7%). About 68.5% were from rural areas and belonged to low socio-economic status (53.2%). Cases were reported mostly in peri-monsoon periods and 65.7% of them came directly to the hospital. CONCLUSION: The study highlights the need to curb the rural spread of the disease through activities in creating awareness among all section of people to promote control measures and early reporting of all fever cases, capacity building of rural doctors for early detection, treatment and early referral of high-risk patients and availability of ELISA based tests in sub-district hospitals along with Rapid Diagnostic Kits (RDKs). Emphasis for preventive and control measures to be increased during peri-monsoon periods and also to be instituted in offices, educational institutes and other indoor activity areas.
