There has been no reported transmissions other than sex, drug use and mother to child?
No, if there is it's because it was "reported" which means a person said this is how they got HIV. But science tells us other wise.
I thought there were a couple skin transmissions listed on the cdc website.
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.
HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug users
Mother to child
