Household Object:

There is no reason to think that HIV could be transmitted through sharing cutlery, plates or cups, because HIV cannot be transmitted in saliva.

Sharing personal items such as razors and toothbrushes generally does not present an effective means for HIV transmission. The short life of HIV outside the body reduces the likelihood of transmission. However, it is preferable to avoid sharing such items, as contact with the first user’s blood is possible as a result of nicks, cuts and bleeding gums in both users.
