i have read an article stating how some people may have been exposed to the hiv virus (and hepatitis) because the hospital didnt use the proper sterilization on colonoscopy equipment. and another similar article that stated those that underwent ear, nose, and throat treatments were exposed too. how likely is someone to catch the hiv virus from a situation like this? even on a re-used blood draw needle (which i know they use new ones, i am just saying IF it happened) how likely can one actually get the virus from this too? thanks for any help.
