Abstract

Background: Dengue is an important public health issue world- wide. There is an increase in number of cases recently and it is con- sidered to be associated with climatic conditions. The present work was done to study the epidemiological trends in dengue and its clinical manifestations. Materials and Methods: The study was conducted in a tertiary care teaching hospital in rural part of South Canara district of Karna- taka. The data was collected using a semi structured pretested questionnaire from January 2016 to December 2018 and presented as frequencies and percentages. Results: 31.10% of the total 1993 suspected samples processed were positive for dengue over a period of three years. Among the posi- tive cases, there was a male preponderance and seen commonly in the 20-49 years age group. There was a positive relationship of the disease incidence with environmental factors. Fever was the most common complaint followed by myalgia and headache. Petechiae was the most common form of bleeding manifestation. More than 90% of the diagnosed cases belonged to dengue fever. ARDS was seen in 1.98% as a complication. Conclusion: Dengue cases are on a rise and are associated with climatic conditions. Continuous surveillance of the cases and mos- quito control measures are essential to control this vector borne disease.
