thanks everyone for the thoughts / prayers / support / info !
found it funny though that the whole time we were in the hospital, we were watching House M.D. episodes
(watched 1.5 seasons)
looking at the incubation period of 3-5 days from the time of the first symptom ... it looks like it was gotten from at home!
(or maybe the incubation period isn't 3-5 days, but longer - that would at least mean it was gotten from elsewhere)
