HIV

HIV stands for human immunodeficiency virus. This is the virus that causes AIDS. HIV is different from most other viruses because it attacks the immune system. The immune system gives our bodies the ability to fight infections. HIV finds and destroys a type of white blood cell (T cells or CD4 cells) that the immune system must have to fight disease.

AIDS

AIDS stands for acquired immunodeficiency syndrome. AIDS is the final stage of HIV infection. It can take years for a person infected with HIV, even without treatment, to reach this stage. Having AIDS means that the virus has weakened the immune system to the point at which the body has a difficult time fighting infections. When someone has one or more of these infections and a low number of T cells, he or she has AIDS 

Origin of HIV

Scientists identified a type of chimpanzee in West Africa as the source of HIV infection in humans. The virus most likely jumped to humans when humans hunted these chimpanzees for meat and came into contact with their infected blood. Over several years, the virus slowly spread across Africa and later into other parts of the world. 

Brief History of HIV in the United States

HIV was first identified in the United States in 1981 after a number of gay men started getting sick with a rare type of cancer. It took several years for scientists to develop a test for the virus, to understand how HIV was transmitted between humans, and to determine what people could do to protect themselves. During the early 1980s, as many as 150,000 people became infected with HIV each year. By the early 1990s, this rate had dropped to about 40,000 each year, where it remains today.AIDS cases began to fall dramatically in 1996, when new drugs became available. Today, more people than ever before are living with HIV/AIDS. CDC estimates that about 1 million people in the United States are living with HIV or AIDS. About one quarter of these people do not know that they are infected: not knowing puts them and others at risk. 

HIV/AIDS Worldwide

  • There are approximately 39.5 million people living with HIV/AIDS worldwide
  • In 2006 there were 4.3 million new infections
  • In 2006 there were 2.9 million deaths
HIV/AIDS in the United States
  • There are approximately 1.4 million people living with HIV (1/4 of them are unaware they are infected)
  • Approximately 43,000 new HIV infections in 2006
HIV/AIDS in Colorado
  • There are 9,884 diagnosed persons living with HIV/AIDS as of 2006
  • 4,918 people have died since the beginning of the epidemic

How HIV Is and Is Not Transmitted

HIV is a fragile virus. It cannot live for very long outside the body. As a result, the virus is not transmitted through day-to-day activities such as shaking hands, hugging, or a casual kiss. You cannot become infected from a toilet seat, drinking fountain, doorknob, dishes, drinking glasses, food, or pets. You also cannot get HIV from mosquitoes.HIV is primarily found in the blood, semen, vaginal fluid or breast milk of an infected person.

HIV is transmitted in 3 main ways:

  1. Having sex (anal, vaginal, or oral) with someone infected with HIV
  2. Sharing needles and syringes with someone infected with HIV
  3. Being exposed (fetus or infant) to HIV before or during birth or through breast feeding

HIV also can be transmitted through blood infected with HIV. However, since 1985, all donated blood in the United States has been tested for HIV. Therefore, the risk for HIV infection through the transfusion of blood or blood products is extremely low. The U.S. blood supply is considered among the safest in the world.

Risk Factors for HIV Transmission

You may be at increased risk for infection if you have:

  • injected drugs or steroids, during which equipment (such as needles, syringes, cotton, water) and blood were shared with others ·
    exchanged sex for drugs or money
  • been given a diagnosis of, or been treated for, hepatitis, tuberculosis (TB), or a sexually transmitted disease (STD) such as syphilis
  • received a blood transfusion or clotting factor during 1978–1985
  • had unprotected sex with someone who has any of the risk factors listed above

Preventing Transmission

According to the CDC, your risk of getting HIV or passing it to someone else depends on several things.  Do you know what they are? You might want to talk to someone who knows about HIV. You can also do the following:

  • Abstain from sex (do not have oral, anal, or vaginal sex) until you marry (are in a relationship with only one person, are having sex with only each other, and each of you knows the other’s HIV status).
  • If both you and your spouse have HIV, use condoms to prevent other sexually transmitted diseases (STDs) and possible infection with a different strain of HIV.
  • If only one of you has HIV, use a latex condom and lubricant every time you have sex.
  • If you have had sex before marriage, consider the following:
  • Get tested for HIV
  • If you are a woman who is planning to get pregnant or who is pregnant, get tested as soon as possible, before you have your baby. It is possible to significantly lower the risk to the baby if you know your HIV status.
  • Talk about HIV and other STDs with your spouse before you have sex.
  • Learn as much as you can about previous partner’s past behavior (sex and drug use)
  • Ask previous partners if they have been tested for HIV; encourage those who have not been tested to do so.
  • Use a latex condom and lubricant with your spouse every time you have sex until both of you know your HIV status
  • If you think you may have been exposed to another STD such as gonorrhea, syphilis, or Chlamydia trachomatis infection, get treatment. These diseases can increase your risk of getting HIV.
  • Even if you think you have low risk for HIV infection, get tested to make sure.
  • Do not inject illicit drugs (drugs not prescribed by your doctor). You can get HIV through needles, syringes, and other works if they are contaminated with the blood of someone who has HIV. Drugs also cloud your mind, which may result in putting yourself at risk.

If you are seeking to overcome a drug addiction, do the following:

  • Get counseling and treatment for your drug use.
  • Never share needles, syringes, or other works.
  • Be careful not to expose yourself to another person's blood.
  • Get tested for HIV at least once a year if you are still injecting.

To protect yourself, remember ABc:
A=Abstinence is the safest way to not be at risk.
B=Be Faithful with an uninfected spouse (The safest way to have sex)
c=condoms will significantly lower one's risk. Only abstinence and mutual faithfulness with an uninfected spouse will eliminate your risk.

Symptoms of HIV Infection

The only way to know whether you are infected is to be tested for HIV. You cannot rely on symptoms alone because many people who are infected with HIV do not have symptoms for many years. Someone can look and feel healthy but can still be infected. In fact, one quarter of the HIV-infected persons in the United States do not know that they are infected.

HIV Testing

Once HIV enters the body, the body starts to produce antibodies—substances the immune system creates after infection. Most HIV tests look for these antibodies rather than the virus itself. There are many different kinds of HIV tests, including rapid tests and home test kits. All HIV tests approved by the US government are very good at finding HIV.

Finding a Testing Site

Many places offer HIV testing: health departments, doctors' offices, hospitals, and sites specifically set up to provide HIV testing. You can locate a testing site by visiting the CDC HIV testing database or by calling CDC-INFO (formerly the CDC National AIDS Hotline) at 1-800-CDC-INFO (1-800-232-4636) 24 Hours/Day.  You do not have to give any personal information about yourself to use these services to find a testing site.
