Chikungunya fever is an arthropod-borne viral disease. Chikungunya and Dengue have a common vector and shows similar clinical presentation. Even though Chikungunya virus infection is self-limiting and less lethal, more than 30% of affected individuals will have post chikungunya chronic polyarthralgia which will affect the patient's quality of life. Reverse transcriptase polymerase chain reaction has high sensitivity and specicity in diagnosis but Enzyme linked immunosorbent assay looks more economical and it provides diagnostic information as well as insights into immune response to CHIKV infection. This is a prospective study conducted from July 2022 to December 2022 in a tertiary care center. Blood samples were collected from the patients presented with acute febrile illness. The samples which were negative for dengue by serological methods were subjected to IgM capture ELISA for chikungunya. Total of 773 samples were negative for dengue fever in patients with acute febrile illness during the study period. These samples were subjected to IgM capture ELISA for Chikungunya. Out of 773 samples 75 samples were positive for chikungunya virus. Total prevalence in the study was 9.7%. Our Study has shown equal sex distribution. Majority of the patients are from urban places. More positive cases were reported in the month of September. Our study has shown that Chikungunya fever is the most important viral illness to be considered in cases of acute febrile illness especially in endemic areas like India, where it goes undetected because evaluation will be more towards dengue fever rather than CHIKV infection. Timely and appropriate management can prevent the complications due to chikungunya and can assist in the prediction and control of outbreaks.
