Introduction: The evaluation of COVID-19 prevalence among healthcare workers (HCW) within the general population of COVID-19 cases is an important epidemiologic variable. The objective of this study is to describe the prevalence and patterns of COVID-19 infection in HCWs amongst a group of patients receiving care for COVID-19 in Rivers state, Nigeria. Methods: This study was a prospective descriptive study of all consenting patients who received care through hospitals, designated for COVID-19 treatment in Rivers state either as in-patient or out-patient following a laboratory-confirmed diagnosis of COVID-19 based on a positive SARS-CoV-2 RT-PCR from April to September 2020. Results: A total number of 646 COVID-19 patients were enrolled over the study period with 98 (15.2%) HCWs in the patient population. The HCWs with COVID-19 consisted largely of Doctors 47 (47.9%), Nurses 30 (30.6%), and socio-sanitary and hygiene workers 10 (10.2%). There were 46 (46.9%) female HCWs, compared to Non-HCWs with 112 (21.1%), females, p = 0.000. Sixty-eight (69.4%) HCWs had a source of contact for infection established compared to Non-HCWs with an established source of contact in 181 (34.2%), p = 0.000. Eight (8.2%) HCWs had Severe disease compared to 52 (9.8%) Non-HCWs with severe disease, p = 0.670. The case fatality in HCWs was 1% compared to 1.9% in Non-HCWs, p = 0.554. Conclusion: The prevalence of COVID-19 among HCWs in the study location is high with clinical and clinical support staff particularly, doctors and nurses are at higher risk of COVID-19 infection. This calls for action to improve and prevent HCWs infections in hospital settings in addition to improving HCW infection prevention behaviour in the community. The intensification of risk communication, provision of protective equipment (PPE), and training on the appropriate use of PPE;in addition to routine surveillance for infection is recommended.
