Any acute respiratory infection with at least one of the following symptoms: cough, sore throat,
shortness of breath, coryza, anosmia, with or without fever.
A sore throat, cough etc are symptoms of acute respiratory infection. A common cold is an acute respiratory infection.
Ah; so I had to Google what Coryza and Anosmia were .. and now I understand better
Thanks for the learnings
neb: Another thing to consider is that you're signalling that you're being careful by wearing a mask. It may do very little to protect you, but it's signalling to anyone you encounter that you're aware of, and taking, precautions to deal with Covid19.
Now I hadn't considered that; cheers for another view.
