Hi, I was in a office function yesterday. There, my colleague feeding a small piece of cake for everyone. He feed a cake to his friend's mouth and immediately feeded the balance cake in my mouth. His friend HIV status is unknown. His finger was touched by his friend's mouth saliva and he immediately feeded into my mouth with the same saliva. My mouth is exposed to his saliva immediately. I am little worried about this situation for HIV transmission.
If his friend is having HIV, does his saliva transmit HIV to me? Because my inner mouth also touched by his saliva immediately.
Kindly help with your answers.
