This study aims to determine the role of personal protective measures in the prevention of COVID-19 spread among the physicians working at different health facilities in Bangladesh. This hospital-based cross-sectional comparative study was conducted from May to June 2020. A total of 98 COVID-19 positive physicians and 92 COVID-19 negative physicians (physicians with no symptoms of COVID-19 or who tested negative) were enrolled. The questionnaire was adapted from a tool developed by the World Health Organization (WHO) for risk assessment and management of exposure of healthcare workers in the context of COVID-19. Data were collected from the respondents online using Google forms. There was no significant difference in baseline information between COVID-19 positive and COVID-19 negative physicians. The physicians, who were unaware of direct participation in COVID-19 patient care, had higher odds of being COVID-19 positive (OR = 4.018; CI: 1.532-10.535). Additionally, the physicians, who were unaware of the COVID-19 status while performing the aerosol-generated procedure (AGP), had a higher chance of being COVID-19 positive (OR = 2.522; CI: 1.020-6.233). Using face shields/goggles (OR = 0.437; CI:0.228-0.837) and regular decontamination of the patient's surroundings (OR = 0.392; CI:0.176-0.873) while usual take care of patients and use of N95 masks while performing AGP (OR = 0.372; CI:0.159-0.873) had protective roles against COVID-19 among the physicians. The physicians who had reused the medical gown had two times more chances of being tested positive for COVID-19 than those who had not reused it (OR = 2.3; CI:1.251-4.259). The use of face shields/goggles and N95 masks and decontamination of the patient's surroundings may give protection against COVID-19. Additionally, reusing medical gowns should be avoided as much as possible.
