Introduction: During the COVID-19 pandemic, hospitals have been busy controlling their spread among healthcare workers, including resident doctors. We seek to characterize and know the transmission dynamics of the SARS-COV-2 infection in the personnel of our hospital.

Methodology: 204 resident physicians were followed up, in three parts: Part 1. Training, Part 2. follow-up through the WhatsApp application, Part 3. case-control study; looking for risk factors.

The statistical analysis was carried out using measures of central tendency and dispersion, comparison of proportions and rates. As well as the calculation of the odds ratio with a 95% confidence interval; p <0.05 was considered significant.

Results: 66 resident physicians were included, 31.8% had a positive result. The mean age was 28.9. The most frequent clinical manifestation was myalgia (66.6%), followed by headache (47%). When comparing with symptomatic resident physicians, with a negative test, there was a significant difference in arthralgia (p = 0.01) and dyspnea (0.05).

Noncompliance with training (OR 7.0; 95% CI 2.2-26 and p = 0.000) was significant as a risk factor for infection.

Conclusions: Resident physicians must be mostly supervised during infection prevention and containment training.
