Background: Chikungunya is a mosquito–borne, viral, acute febrile illness that can be difficult to distinguish clinically. Since the incidence of this disease is increasing, it is necessary to study the incidence and prevalence of the disease to find out the measures to stop the spread of the disease. The study was done as epidemiologically in kota region in all age group.

Materials & Methods: This was a retrospective study conducted in the microbiology department of a Government Medical College Kota (Rajasthan) during one year period (November 2015 to November 2016). The study included 2600 patients of all age group who had clinically suspected cases of characterized by acute illness with fever, skin rash, painful myalgia and polyarthralgia. ChikungunyaIgM antibodies were detected in serum by IgM capture ELISA

Results: 2600 serum samples from suspected cases were tested for presence of IgM antibody and in 330 it was found to be positive. The number of suspected cases has increased significantly over the study period. CHIKV was more common in respectively. Cases were seen throughout the year the maximum was in post monsoon season. Males were the predominant sufferer 53.40% and female was 46.60% of the total suspected. All the age groups suffered from CHIKV but maximum number of majority were from 21–60 years of age group.

Conclusions: Present study was undertaken to determine the epidemiology of Chikungunya fever that the incidence is across a wide age group with year round involvement of large number of patients. Chikungunya fever is self limiting; the morbidity can be very high in major outbreaks in all age groups, resulting in a heavy social and economic tolls. The prevention of the disease requires a planned approach, besides knowledge and awareness on the early warning signs A community empowerment and mobilization is crucial for the prevention and control of Chikungunya.
