We enrolled 379 healthcare workers, hospital staff, and their family members who were tested for COVID-19 by reverse transcription-polymerase chain reaction (RT-PCR) in an outpatient clinic. Socio-demography and the infection prevention practices of the individuals were recorded in a preformed questionnaire. Statistical analysis was performed to find out the statistical association between these factors and the RT-PCR results. Adjusted and unadjusted odds ratios were determined to find out the degree of protection provided by each of the preventive practices concerning the development of the disease.
