No you can not contract HIV in that manner.
Thank you very much Mr Teak, i was really worried as one of my relative is HIV positive and i went to see him today, i didn't wanna offend him(No offense just lack of awareness) him so sat next to him, we spent time together, ate together and it was all fun but he was coughing and i felt it on my face and i more than once that is why i raised this question. So on the basis of given facts i cannot contract HIV?
So i wouldn't contract HIV through mucus even if mucus contains infected blood?
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
