The aim of the present article was to assess PTSD in military health staff, considering the characteristics of this type of environment, and specifically during the pandemic for COVID-19. The Davidson Trauma scale was presented through the survey monkey ® platform, digital consent was provided by the personnel, users solved the instrument on their own personal devices. Results showed an incidence of PTSD of 0.9% in a sample of 1422 subjects who  work in the Central Military Hospital; the most frequent symptom, and the most serious were the avoidance of doing things or being in situations that reminded the event, regardless of gender or age. We found a more risk of PTSD in females than in males (Odds ratio (OD) = 6.4; 95% confidence interval (CI) = 0.83 to 49.66). However, we did not find a correlation between age, hierarchy or professional group and the risk of PTSD.
