Descriptive analysis was performed. Results:912 surveys were included, 62.2% were female (n=567), 82% said they had received information related to covid-19 from reliable information sources (n=748), 96.5% talked to their family and friends about prevention measures (n=880), 63.8% were unaware of N95 mask use during intubation, suctioning, bronchoscopy and cardiopulmonary resuscitation procedures (n=582) and 43.3% indicated that they were afraid of becoming infected (n=395).Conclusion: most of the participants reported having received adequate information to learn about aspects related to covid-19, but were unaware of essential aspects such as the use of N95 masks. It is necessary to educate and inform the medical school student population in order to decrease the perceptionof risk and increase prevention behaviors.
