Help with Comparison?

Question

Can anyone give me a list of the similarities and differences between SARS and HIV? Thank you~

Answer 1

both of them are contagious, although SARS is transmitted through droplets in the air (like when you sneeze), while HIV is caught by having sex with someone who has it.
both diseases will most likely lead to death. however, SARS has a more immediate effect (victims can die in about a week) than HIV. also, its effect is far more direct; HIV only lowers the immune system in such a way that even a common cold can be deadly (in fact, people who die of AIDS die because of indirect causes).
both diseases come from animals (i think).
the two of them still has no cure.
