A cross-sectional study was conducted on medical students at a private Peruvian university. The objective was to describe knowledge and attitudes towards COVID-19 and the student’s perception of the role of media outlets and social media. 32% of students did not know that serological tests are preferable to molecular tests to diagnose COVID-19 in the first five days of illness; 73% reported being willing to work as a volunteer during the pandemic, and 94% received false information regarding COVID-19 on social media. This study demonstrates that information regarding diagnostic tests should be reinforced and that the high percentage of students willing to volunteer during the COVID-19 pandemic should not be overlooked.
