College Beer Mugs

Hypothetical question about AIDS and HIV Virus?
Remember, this is a completely hypothetical question. Tom and Jerry are best friends and colleagues fourth in college. They drink beer and smoking just two cigarettes only. No other alcohol or drugs of any kind. Tom is HIV-positive and HIV-negative Jerry and both know it. One night they both go to a bar. 2 hours later, Tom has to pee, leaving about 2 sips of beer in the cup and a cigarette three quarters of the way done. The Bartender (Do not know about HIV status) asked if they want a refill on it. Jerry finished the last of the beer to avoid wasting Tom, Tom grabs the cigarette and ends and says yes to recharge them as statements of Tom at the bar. Jerry Can contracting HIV because he finished the beer and cigarettes from Tom?
no. HIV / AIDS is a sexually transmitted disease. which means they have to come into contact with any bodily fluids that transmit data such as: semen, blood, etc.. In rare cases, HIV was transmitted through breast milk. It is highly unlikely that the capture of HIV / AIDS in the saliva, but occasionally it happens.
