henlo, /sci/ retard here

given that the main way corona kills is by infecting the lungs and destroying it, why can't we just swollow a pill that breaks in our stomach/early intestines and then we have a intenstinal infection. severe diarheas is better than not breathing, right? provided that the person doesnt eat his own shit, isn't it a good way of imunyze people?
plz keep bully to a minimum
