Here's a link that tells of actual IBD patients who had Covid 19. It hasn't been updated for a couple days ... not sure if that is good news or bad.
From everything I am hearing it sounds like 50-80% of the population will contract this eventually. We need to hope we can avoid it long enough for treatments to be developed.
I'm going to guess it hasn't been updated due to a large number of new data, which they may process rather than giving a long list. Of course, it might just be that the people maintaining the website have been too busy to post an update
