What is HIV?

HIV stands for human immunodeficiency virus. HIV weakens a person’s immune system by destroying important cells that fight off infections.  Our immune plays an important role in protecting us from pathogens like bacteria, viruses, and fungi and untreated HIV can reduce the ability of the body to fight off these infections.

There is currently no curet for HIV, but treatment for HIV is very effective. With treatment a person can live a long healthy life.

HIV treatment is so effective that it can reduce the amount of HIV virus in a person’s body to an undetectable level. Someone with a undetectable level of HIV in their body (also called an undetectable viral load) cannot pass HIV on to their partner(s). This is called U=U or undetectable = untransmittable and it is 100% effective in preventing the sexual transmission of HIV and also helps to prevent passing HIV from sharing syringes, childbirth, and breastfeeding.

Getting tested is the first step!

HIV  Fast Facts

What is HIV?

HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. Without treatment it can lead to AIDS (acquired immunodeficiency syndrome) also called stage 3 HIV which can be life threatening. 

HIV can affect anyone who has unprotected sex, regardless of gender or sexual orientation.

The only way to know your HIV status is to get tested. There are many options for quick, free, and painless HIV testing. Health departments can confidentially test you and your partner(s) any time for HIV.  If your test result is positive, there are safe and effective treatments to help you live a long, healthy life, and protect others. If your test result is negative, there are prevention options to prevent getting HIV. 

The CDC recommends that everyone between the ages of 13 and 64 get tested for HIV at least once. People who might have ongoing vulnerability should get tested more often. 

Most people have flu-like symptoms within 2-4 weeks after getting HIV and those symptoms can last for a few days or several weeks. Some people have no symptoms at all. The only way to know if you have HIV is to get tested.

Most people who get HIV get it from anal or vaginal sex, sharing needles, syringes, or other items used to inject drugs. HIV is spread through blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk. 

Yes! There are many effective tools to prevent HIV and many can be combined. 

  • Using condoms the right way when you have sex
  • Never sharing needles, syringes, or other items used to inject drugs
  • Taking PrEP (pre-exposure prophylaxis) or PEP (post-exposure prophylaxis)


*It’s important to note that people who are living with HIV that are on effective treatment and have a sustained undetectable viral load cannot pass HIV to overs through sex. See more about this in the U=U section.

HIV is treated with ART (antiretroviral therapy). ART is safe and effective and should be taken as soon as possible after an HIV diagnosis. HIV treatment reduces the amount of HIV virus int he blood (viral load). HIV treatment can make the viral load so low that a lab test cannot detect it. This is called an undetectable viral load.  Having an undetectable viral load (or staying virally suppressed) is the best thing a person living with HIV can do to stay healthy. It also means that person cannot pass HIV through sex to others (U=U).

U=U means undetectable equals untransmittable. It means that a person with a undetectable viral load cannot pass HIV to others through sex. Having an undetectable viral load also reduces the risk of HIV transmission through sharing drug injection equipment and during pregnancy, labor and delivery. 

When people get HIV and are not in treatment, for whatever reason, they typically progress through three disease stages. HIV treatment can slow down and even prevent this progression which is why Stage 3 (AIDS) is far less common today. 

Stage 1: Acute HIV 

  • People have a lot of HIV virus in their blood and are more likely to pass HIV on to others
  • May experience flu-like symptoms

Stage 2: Asymptomatic HIV (also called Chronic HIV or clinical latency)

  • HIV virus is still in the body and reproducing
  • People may have no symptoms but they can still pass HIV on to others
  • People on treatment for HIV may never move into Stage 3 (AIDS). Those without HIV treatment may experience this phase for a decade or longer or they could progress to Stage 3 much quicker

Stage 3: Acquired Immunodeficiency Syndrome (AIDS)

  • This is the most severe stage of HIV
  • An AIDS diagnosis is given if a persons CD4 (immune cell) count drops below 200 cells per mL of blood or they develop certain very rare illnesses
  • People with AIDS can have a high viral load and may be able to easily pass HIV to others and may get an increasing number of very serious illnesses
  • Without treatment, people with AIDS typically survive about 3 years

 HIV Community Planning in Tennessee

HIV community planning in Tennessee is based on a grassroots system that empowers local, community-based stakeholders to guide how state and federal dollars are spent and to shape emerging state prevention efforts. 

Each of the six regions across the state has a Community Planning Group (CPG). These groups meet regularly within their communities and have standing by-laws and operating procedures. These groups inform HIV Prevention and Ryan White (Parts A and B) efforts in their regions.
