The 3 M is an information campaign to help raise awareness about the importance of good practices that minimize the risk of contagion by Covid-19 in the university environment. The title recalls the three basic prevention measures: hand hygiene, correct use of the mask and maintaining ventilation. It is an initiative of the Vice-Rector's Office for Employment and Training Programs, managed by Sedi, which invites students interested in helping to disseminate protection measures against Covid-19, based on scientific rigor, by training and participating in a campaign awareness-raising aimed at the university community.
