No one has been identified as infected with HIV due to contact with an environmental surface. Additionally, 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.

my cousin said that virus wouldnt be able to live because of the alcohol...is this true?
No it is not possible to contract HIV from drink after anyone with HIV>
