A friend of yours has been hinting about maybe going to get testes for HIV-AIDS but didn't seem to know where to go and if they were infected. What could you tell them about HIV-AIDS including where to get tested in your community, who to talk to, important information about testing, how to stay protected, etc? Provide facts about who can be infected, best way to protect yourself, etc. 

Can you also protect yourself from infectious diseases? What are some of the strategies you would use?
