The Smithsonian Institute in the US calculated how far one should stand away from someone who’s sick to avoid the virus-containing droplets they expel into the air when they cough, sneeze or talk.
These respiratory droplets can travel up to 1.8m.
So, your best chance to remain uninfected is to keep a distance of at least 1.8m from those with a cold or the flu, and move away quickly when they’re about to sneeze.
