It's not just about distance
Timing is also key. The longer you spend in close proximity with an infected person, the bigger the risk.
Scientists advising the UK government say that spending six seconds at a distance of 1m from someone is the same as spending one minute at a distance of 2m.
Being exposed to someone coughing is riskier. Being 2m away from a cough carries the same risk as someone talking to you for 30 minutes at the same distance.
