Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Infected blood ____ spread HIV.
A
cannot
B
can
Explanation: 

Detailed explanation-1: -Medical Care. The US blood supply and donated organs and tissues are thoroughly tested. It is very unlikely that you would get HIV from blood transfusions, blood products, or organ and tissue transplants. You cannot get HIV from donating blood.

Detailed explanation-2: -HIV is passed on through blood, semen, vaginal fluid, anal mucus and breast milk, if the person with HIV has a detectable viral load.

Detailed explanation-3: -The risk rises as the number of units transfused increases. For example, under baseline assumptions the risk from a single unit of blood is approximately 1 in 99, 000; from 5 units the risk is 1 in 20, 000; and from 10 units the risk is 1 in 10, 000.
