How do aerosols behave? How does the Covid-virus travel through air?

In a closed environment, heavier particles can travel up to 2 metres. The smaller particles and aerosols (produced when coughing, sneezing or talking) can travel up to 10 metres and stay suspended in the air for hours.

Some aerosols can carry active viruses. When inhaled, these aerosols are a source of transmission. Indirect contamination can happen when touching your mouth, nose or eyes.
