actually what are the doubts i am having are relates to one incident..i dont know if it is ocd or not but every time i m freaking bout the non sexual risks of aquiring hiv.1)www3.interscience.wiley.com/journal/122577490/abstract?CRETRY=1&SRETRY=0...recently while searching about research on hiv saliva,i came to know that xerostomia is there in hiv people from the mentioned site..and xerostomia is characterised by dryness of mouth and it causes bleeding gums..and hiv patients also have canker sores and some times herpes also..so the saliva is less....i got several spit sprays on my eyes and mouth while going through crowd in the market..they usually have the habit of chewing recreational mouth chewers such as paan,(beetel leafs and areca nut) in my south india..so the risk of mouth ulcers are more in hiv people..so the blood containing from a xerostomial mouth to my eyes carries a risk ..! in this way i am asking about my doubts...and the cdc states that the mucous membrane exposure risk is 0.1% but i dont know this risk is before taking pep or after taking pep? ofcourse mine is not an occupational exposure but i am comparing with that occupational senario....thank u waiting for your reply...chintu58
