Recently has been identified as global health emergency. This study aimed to determine seroprevelance of COVID-19 among health care workers (HCWs) in northern state, from May 2020 to June 2021. A total of 394 serum samples randomly selected for this cross-sectional study. Participants were screened for COVID-19 antibodies (IgG) using SARS CoV-2 antibody test (Lateral Flow Method). Demographic data were collected using structured questionnaire. The risk analysis identified independent predictors of COVID-19 seroprevelance. The overall seroprevelance was found 1.77%. High prevalence was found among laboratory workers (52/ 6%) and more males (156/3.2%) were affected than females (238/0.8%). Moreover, age was found as a major risk factor and the median age of infection is around 50 years. Considering rapid growth and high transmissibility of the virus, it would be important to encourage all efforts to protect HCWs, in order to maintain health care system.
