PREVALENCE • AIDS was first identified in 1981 among homosexual men and intravenous drug users in New York and California. • Shortly after its detection in the US, evidence of AIDS epidemics grew among heterosexual men, women, and children in sub-Saharan Africa. • AIDS quickly developed into a worldwide epidemic, affecting virtually every nation.

• Worldwide more than 80% of all adult HIV infections have resulted from heterosexual intercourse. • About 40, 000 new HIV infections occur in the US each year. • Almost 1 million people are living with the HIV infection or AIDS in the US today.

What is 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 CD 4 cells) that the immune system must have to fight disease. All information has been provided by www. aids. gov

Where did HIV come from? • 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. All information has been provided by www. aids. gov

How is HIV transmitted? • The most common ways that HIV is transmitted from one person to another are: – By having sex with an HIV-infected person – By sharing needles or injection equipment with a person who is infected with HIV – From HIV-infected women to their babies before or during birth – Through breast feeding All information has been provided by www. aids. gov

HIV can be found in body fluids, including: • • • blood semen vaginal fluids breast milk some body fluids sometimes handled by healthcare workers (fluids surrounding the brain and spinal cord, bone joints, and around an unborn baby) All information has been provided by www. aids. gov

HIV cannot be transmitted by casual contact. Here are the facts: • You cannot get HIV from: – Shaking hands or hugging a person with HIV/AIDS – Using a public telephone, drinking fountain, restroom, swimming pool, Jacuzzi, or hot tub – Sharing a drink – Being coughed or sneezed on by a person with HIV/AIDS – Giving blood – Mosquito bite All information has been provided by www. aids. gov

Abstaining from (not having) sex is the most effective way to prevent HIV transmission. • There are several ways to protect yourself or to prevent transmitting HIV if you choose to have sex: – Get tested for HIV and know the HIV status of yourself and your partner – Be faithful to your sexual partner – Use condoms or other latex barriers during vaginal, oral, and anal sex, and never reuse condoms or latex barriers All information has been provided by www. aids. gov

Symptoms • rapid weight loss • dry cough • recurring fever or profuse night sweats • profound and unexplained fatigue • swollen lymph glands in the armpits, groin, or neck • diarrhea that lasts for more than a week • white spots or unusual blemishes on the tongue, in the mouth, or in the throat • pneumonia • red, brown, pink, or purplish blotches on or under the skin or inside the mouth, nose, or eyelids • memory loss, depression, and other neurological disorders All information has been provided by www. aids. gov

How do I know if I have HIV? • The only way to know if you are infected is to be tested for HIV infection. • You cannot rely on symptoms to know whether or not you are infected. • Many people who are infected with HIV do not have any symptoms at all for 10 years or more. All information has been provided by www. aids. gov

Stages of an HIV infection. 1 st Flu-like illness – usually happens 3 -6 weeks after exposure to HIV, but can happen in just a few days. 2 nd HIV (asymptomatic) – Many people go for years without any symptoms Ø Still is replicating Ø After years of replicating it weakens the immune system All information has been provided by www. aids. gov

Stages of an HIV infection. 3 rd HIV symptomatic – Is characterized by symptoms discussed earlier ØSigns of immune system failure ØUsually occurs after CD 4 cells drop to below 500 ØMay not occur till 12 years after infection 4 th AIDS – last stage of infection All information has been provided by www. aids. gov

How does HIV cause AIDS? • HIV destroys the blood cell CD 4 (T cells) • These are crucial to the normal functioning of the immune system. • When HIV infects a CD 4 cell, it commandeers the genetic tools within the cell to manufacture new HIV virus. • The newly formed HIV virus then leaves the cell, destroying the CD 4 inby the process. All information has beencell provided www. aids. gov

What is 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 All information has been provided by has AIDS. www. aids. gov

Little more about CD 4 cells • The average healthy person has between 500 & 1, 400 CD 4 cells per mm 3 (Cubic Millimeter) of blood. • In a person infected with HIV, the virus steadily destroys CD 4 cells over a period of years, diminishing the cells’ protective ability and weakening the immune system. • In HIV infected individuals, a CD 4 cells drops to 200 cells per mm 3 of blood a person is considered to have AIDS All information has been provided by www. aids. gov

Opportunistic Infections • As HIV attacks the human immune system, the immune system weakens over time and becomes more susceptible to opportunistic infections (OIs). • Opportunistic infections are generally illnesses that don’t make people with a healthy immune system sick or don’t occur as often. • There are many kinds of opportunistic infections, including other viruses, bacterial infections, and some types of cancers. • Even common colds can become more dangerous and the flu is considered a serious condition in persons with HIV/AIDS.

To name just a few, common HIV/AIDS related health issues include: • • • Tuberculosis (TB) Hepatitis C Cryptoccocal meninigitis Pneumocystis carinii pneumosia (PCP) Cryptosporidiosis (crypto) Toxoplasmosis (toxo) All information has been provided by www. aids. gov

Living with HIV/AIDS • There is no cure for HIV or AIDS • HIV drugs can slow down the virus’s attack on the human immune system. • People with HIV/AIDS can now live healthier, longer lives. • While treatment has its benefits, it also has its risks, such as multiple side effects from HIV drugs and therapies, potential toxicity from drug treatments, as well as possible resistance of HIV to drugs over time.

Getting tested & Tests All information has been provided by www. aids. gov

What do tests look for? • Tests do not look for HIV in blood. • They look for antibodies produced by the body in an effort to fight HIV. • Antibodies can be detected anywhere from a few weeks until six months (very rare) All information has been provided by www. aids. gov • Average time is 25 days.

• Western Blot – Test is more specific and can tell the difference between HIV antibodies and other antibodies – Used to confirm all other tests. • Rapid HIV Tests – A rapid HIV test usually produces results in less than two hours. • Home Test Kit – Testing involves pricking your finger, placing drops of blood on a treated card and mailing the card in for testing at a licensed lab.

Treatments All information has been provided by www. aids. gov

What is HIV antiretroviral drug treatment? • It is not a cure, but it can stop people from becoming ill for many years. • The aim of antiretroviral treatment is to keep the amount of HIV in the body at a low level. • This stops any weakening of the immune system and allows it to recover from any damage that HIV might have caused already. All information has been provided by www. aids. gov

What is combination therapy? • Taking two or more antiretroviral drugs at a time is called combination therapy. • If only one drug was taken, HIV would quickly become resistant to it and the drug would stop working. • Taking two or more antiretrovirals at the same time vastly reduces the rate at which resistance would develop, making treatment more effective in the long term.
