I use it for the common cold which is a corona virus also. It has stopped me needing Antibiotics . I always needed Antibiotics as I would get chest infections but not anymore, I don’t get chest infections anymore. I posted further down in this forum, it defo works for a cold as long as I use it at the first sign of a cold but this new corona virus isn’t the common cold is it, symptoms can take 14 days to appear and a person is contagious right up to the day symptoms appear.
