If you're @ Kalaupapa, I'd think that the State of Hawaii Dep't of Health (or whatever it's called there) would have jurisdiction over health care delivery; maybe you could suggest getting guidelines from that agency, and using them.
If the USPHS is the agency involved, I'm sure CDC's recomendations would be appropriate, (they would be no matter what--the ultimate authority on stuff like that!) I'll find that web site and edit my message after I find it.
Hepatitis B is a blood-borne pathogen; I don't know how his living conditions could have caused it. He could have gotten it from a blood transfusion, esp if he got it before blood banks knew about or tested for Hep B. Knowledge about Hep B really came out in the mid 70's--before that, he could have had it and no one would have known.
If he was in the Korean War, he could've gotten it there--there was an outbreak among soldiers of a hepatitis that no one could diagnose because the tests didn't exist. BUT...some bright-eyed epidemiologist @ the CDC drew blood (or more likely, had the Army do it), froze the serum, and when they finally developed the Hep tests, they checked the frozen serum, and voila!, epidemic solved.
If this little guy went somewhere, got hospitalized, and some well-meaning, but unknowing, personnel isolated him innappropriately isolated him because he comes from Kalaupapa, what would your dinosaur/colleagues have to say? I don't think it would be too pretty!!
Aloha to you!

p.s. as promised, I'm back w/the www's:
for stuff re: isolation in gen'l
for info on diseases--use the index search right on the home page for the alphabetical listing--it's a feww spaces after Hansen's! Good Luck w/ your dinosaurs!
