Which is the most unlikely way to contract hiv in the united states? a-by an infected mother breastfeeding her child b-through sharing needles with strangers during intravenous drug use c-through unprotected sexual contact with an infected person d-through a blood transfusion supervised by a doctor

D- through a blood transfusion supervised by a doctor

Explanation:

All of the options given in the question are ways to infect a healthy person with HIV, however, the least likely form of this infection to happen in the US is through a doctor-supervised blood transfusion. That's because all donated blood in the US today is highly tested, not just for HIV, but for many other diseases. If blood is infected it is quickly discarded. For this reason, it is highly unlikely that a person will contract HIV through a doctor-supervised blood transfusion.
