There’s building scientific evidence that certain behaviours and contexts increase the likelihood of COVID-19 transmission and infection. Because the virus is primarily transmitted through tiny airborne droplets called aerosols, the use of masks and maintaining physical distance are of paramount importance to prevent the spread and reduce risk of infection (1, 2).

Keeping gatherings outdoors is also recommended (2, 3, 5).
