Hi lybrate-user! HIV
spreads only through sex or blood transfusion and not through drinking or eating, but still if you have doubt just wait for a week or so and take a blood test. Before that confirm if your friend has HIV or not. Precaution is better than cure. Moreover alcohol itself will kill the virus if the blood drop fell in the alcohol. To rule out your doubt you can take a test in a week or so. Better confirm with your friend if he has taken all the blood tests etc. Indirectly just to clear your doubt. Take care. Be relaxed.
