Reply To: question about corona
That depends on the circumstances…
How many viruses does the infected person have in his/her airways?
How close are people standing together?
Are we inside or outside?
If we are outside, which way is the wind blowing?
What is the temperature?
Is anybody wearing a facemask?
Is the infected person sneezing/coughing?
So, like most things in life, there is no simple answer.
