Background: Dengue is an important vector-borne disease with a spectrum of classical fever to hemorrhagic fever to dengue shock syndrome. The present study was conducted with objective to study epidemiological and demographic characteristics of dengue infections during the year 2015 in Saurashtra region, Gujarat state, India. Materials and Methods: The study was conducted at Tertiary Care Hospital, Rajkot, during the year 2015. A total of 3312 blood samples were collected and tested for dengue NS1 antigen and IgM antibody by capture ELISA testing from various districts of Saurashtra region. A pretested structured data sheet was used as a tool for data collection, and data analysis was done. Results: Out of 3312 tested samples, 33.4% samples were found positive for dengue. Suspected cases were reported from all age groups, including majority from 15 to 24 years (31.1%) and 25 to 44 years (30.0%) and also 8.4% from 0 to 4 years. More than two-third (68.7%) of males were dengue positive than female cases. Significant numbers of cases (P < 0.01) were residing in urban areas (65.7%). Two-third cases (66.8%) diagnosed after 7 days of fever by IgM antibody test. Increasing number of dengue cases reported from July and reached to peak during October 2015. Conclusion: The present study reported that dengue mainly affected males and urban population. Perennial occurrence with seasonal increase during monsoon and postmonsoon months was reported. Effective implementation of vector control measures through efforts toward vector breeding source reduction and with the use of personal prophylactic measures against mosquito bites will help in reducing the dengue prevalence in the community.
