Here are three of the best sites on the internet that I found relating to HIV and AIDS:

The Body

This is probably the best site out there regarding HIV and AIDS.  They have a large quantity of information on all aspects of the disease.  It’s fairly easy to navigate, and is probably the only site you would ever need.  There is an extensive question and answer section where people write their questions in, and those questions are answered by experts in the field.

Johns Hopkins AIDS Service

This site also has an extensive amount of information regarding HIV and AIDS, but is primarily intended for those already infected.  There is also an question and answer section with one of Hopkins’ doctors.  I recommend reading some of those, if you’re so inclined.  Although not always, he frequently is rather amusing in his responses to questions.

Center For Disease Control (CDC) Site

This is the CDC’s site for HIV and AIDS.  Although full of information, it isn’t the easiest site to navigate around.  Also, when reading the information, you have to take it with a grain of salt. Remember, the CDC are the ones responsible for putting an end to this epidemic, so the information they provide will tend to favor conservativeness.  For example, when reading “Can I get HIV from receiving oral sex?” their answer is “yes”, despite the fact that no one ever has.  This is because they want to make sure that even theoretical ways of transmission are kept in check.

In addition, the CDC runs a hotline which is open 24 hours a day, 7 days a week.  I have called them several times myself, and have consistently found the people to be very nice, respectful and extremely well-informed.  If you would like to call them with any questions or concerns you may have, the number is 1-800-342-2437 (Spanish/Español: 1-800-344-7432; TTY access: 1-800-243-7889).
