Early signs of it can be mixed up with flu like symptoms because they are very much alike. You have fatigue, chills, rash, fever, etc. It also can take a couple weeks or more for symptoms to start after infection.

Although HIV is not curable, the best treatment for it is antiretroviral therapy(ART). This is taking lots of medications on a regular schedule to keep your immune system up and fighting. If not treated correctly it can lead to AIDS which is a chronic but worse condition.

Prevention from HIV can be to always use protection properly during intercourse, do not needle share, and there is also a pre- and post- exposure to people that have been exposed to it that help them not get it. If you are having sex with multiple people make sure to get tested regularly.
