Can HIV be transmitted through sharing drinks when both people have bleeding wounds in their mouths?
Yes, transmission is theoretically possible in this specific situation, though it remains very rare. HIV cannot spread through saliva alone because saliva contains enzymes and antibodies that prevent the virus from spreading to other cells.
However, when both people have actively bleeding wounds or open sores in their mouths, transmission could occur through blood-to-blood contact. If blood from one person's wound enters the other person's wound while sharing a drink, the virus could potentially be transmitted — but not through the saliva or the beverage itself.
This type of transmission seldom occurs in practice. The key risk factor here is the presence of blood from bleeding gums or open wounds in both people's mouths, not the act of sharing drinks.
To reduce risk, it's best to avoid sharing drinks or utensils when you have bleeding gums or open mouth sores. Using condoms during sex, not sharing needles, and ensuring viral suppression through antiretroviral therapy are the most effective ways to prevent HIV transmission.
