Im replying to myself since I cant help thinking of something more interesting ... If you actually have the ability to study 22K+ individuals during a covid outbreak and found TEN people that had a 'cold' ... why wouldnt you study that? TEN people managed to get a cold but not covid? Seems worth looking into.
