This is frightening. It can happen to anyone who decides to use a public restroom.
You are probably OK but if unsure you could visit the hospital, there is a 24-72 hour kit you can get which can prevent HIV.
This also happened to me twice where a public sink had blood in the faucet somehow from someone's mouth.
Both instances I turned up clean, in one of them I had scabs on my hand.
NO. HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.
