Testing was done as per the Centers for Disease Control guidelines at nine laboratories approved by the Government of Rajasthan. Data were analyzed in terms of demographic characteristics, clinical presentation and outcome.Results:Among 18,187 tested cases, 6203 (34.10%) were positive. Death occurred in 378 cases, with six per cent case fatality rate. Maximum number of cases (n=2801) and deaths (n=101) were from Jaipur zone. The highest number of cases, 47.60 per cent (2953/6203) and deaths, 52.11 per cent (197/378) were in the age group of 26-50 yr; 52.64 per cent (199/378) of deaths occurred in females.
