Globally, frontline health care providers are among the most affected population group by the COVID-19 pandemic. Knowing the factors contributing to the transmission of COVID-19 infection among frontline health care providers is essential for implementing tailored control measures and protecting this vital population group. This study aimed to estimate the proportion and to identify factors associated with COVID-19 infection among medical doctors in Sudan. A web-based survey was used to collect data from medical doctors who were working in Sudan during the study period. Data were analyzed using SPSS.sup.® version 25; Descriptive analysis in terms of means (SD) for continuous variables, frequencies, and percentages with 95% CI for the categorical variable was conducted. Chi-square test and binary logistic regression for associations between the outcome variables (risk of exposure to COVID-19 infection and ever tested positive for COVID-19 infection) and independent variables (socio-demographic and infection control standards) were also performed. Out of 352 valid responses, 13.6% had tested positive for COVID-19 infection at least once during the pandemic. More than one-third have identified colleagues as the main sources of infection compared to 21% of patients (p-value < 0.04). Doctors who received training on COVID-19 were 60% less likely to have positive tests for COVID-19 (p-value <0.03), while lack of PPE and hand hygiene utilities had no statistically significant associations with testing positive for COVID-19 infection. In conclusion, a significant proportion of doctors have contracted COVID-19 infection from their colleagues. This calls for restricting infection control practices at hospitals, doctor's doormats, and any other shared places that allow day-to-day interaction between doctors and their colleagues. Also, urgent need for training doctors on COVID-19 infection control practices as it has been identified as the key protective factor.
