Question

List two reasons why HIV/AIDS continues to spread so rapidly across the world.

Answer 1

HIV/AIDS continues to spread due to people using HIV contaminated needles to do drugs. drugs users typically share needles which can put the blood of an HIV infected person into a healthy persons blood which will give them the disease. another reason the disease spreads is that people who carry HIV have sexual intercourse with someone who does not have the disease, which can lead to it spreading as well.
