From what I've been able to find out, that infection has a generally good prognosis, but the treatment can take several months, most of which is usually out of the hospital. It's known as an atypical Mycobacterium, which means it is related to the germ that causes tuberculosis, but it is NOT contagious. It's not often easy to make the diagnosis, and the fact that the doctors did find out is a good indication that he's in very good hands.

Ron, I'd be happy to have Rosemary get in touch with me if she or Cyril have any questions; I can contact infectious disease specialists over here if there are questions I can't answer. Having sung and loved his songs for years, it's the least I can do! You can send me a PM and if they are interested we can work out the logistics. And just to be clear, that's not at all meant to suggest any doubts about his doctors. As I said, it sounds like he is in very good hands. But explaining medical conditions in understandable terms is kind of an avocation of mine--and sometimes it helps to have more information. Other people are very comfortable just talking with their doctor.   Chacun à son gout!

Aloha,
Mark
