HIV Info

Of the more than one million people estimated to be living with HIV in the United States, one in five don't know they're infected. The best way to fight HIV is to know your status.


If you think you may have been infected with HIV/AIDS, we encourage you to get a free, confidential HIV test.

Have questions about HIV/AIDS? We have answers to Frequently Asked Questions.

HIV stands for the Human Immunodeficiency Virus, and is the virus that causes AIDS (Acquired Immune Deficiency Syndrome).  It is a virus that attacks the immune system. 

Over time, and without treatment, HIV gradually destroys the body's defenses against disease, leaving it vulnerable to many infections and cancers that do not normally develop.

AIDS is a late stage of HIV disease.  By the time of an AIDS diagnosis, HIV has already seriously damaged the body's immune system.  Often, a person living with AIDS will already have had life-threatening infections or cancers.
