Wow! you must of read so much wikipedia to gain that knowledge. Actually you seem to guess yourself on how important the intestines ( which includes the colon) area without really knowing without your intestines/immune system....you can die from the common cold.
Oh well you and stealth think animals like dolphins will get AIDS cause they follow the same Homosexual( Which a sexuality attraction between same sex Humans) Patterns.
Contradictions my friend.
Actually, I'm in an Immunology course at this very minute. It's undergraduate, but pretty well done. Just finished my final on Friday. No one dies from rhinovirus unless they are severely immunocompromised. Like, unless they have AIDS. I know how important intestines are, but I personally think you're overvaluing them. Comparatively few virii reach that point because of low pH presented by the stomach and passive immunity in the respiratory and early GI tract. The only MAJOR viruses that will are Hep A and Rotavirus.
I stealth think that dolphins will get aids? I can't even begin to propose a situation in which that would happen outside of some crazy vet environment, and even if there was species->species transfer, it wouldnt even epidemize because of how disparate dolphin populations are.
Dont assume shyt about me, and if you're trying to go at my knowledge base at least try harder. Or propose a question id need to look at papers to figure out. Because the bolded is pathetic. Arms too short to box...
