Okay so my friend found out that hes HIV positive. And I was wondering, this is a weird question but he has this spiky thingy for his teeth and he bleeds from his gums sometimes and the blood is probably on the object
And if somebody else also uses that object for their teeth and also bleeds, will the person also get infected or is it rare to get infected like this?
HIV doesn't survive for very long at all outside of a host environment - it needs living cells. All studies have show that dried blood has 'essentially zero' risk of infecting another person.
So, it is technically possible I suppose, that someone could have his infected blood, make contact with an open wound in their mouth, and get infected in that way... but it's not terribly likely. Effectively washing and drying his plaque brush thingy should decrease the risk to virtually nothing. [ Razhie's advice column | Ask Razhie A Question ]
