3 Human Immunodeficiency Virus An infection in which HIV enters the blood and is multiplying in the person’s cells.
4 Healthy people carry about Helper T cells ~ white blood cells that activate the immune response when a pathogen enters the body.Healthy people carry about500 – 1500helper T cellsin about20 dropsof bloodVideo on picture
5 The process of replication then starts over. HIV attaches itself to helper T cells. The virus forces the T cells to make copies of the HIV, this isreplicationNew viruses are released from the T cells and they attach to other cells.The process of replication then starts over.
6 When a person’s white blood cell count gets As more helper T cells are lost, the immune system is less able to fight off infection. This could take years.When a person’s white blood cell count getsbelow 200 per milliliter of blood, they are said to have AIDS.

11 In the first stages of HIV infection, most people will have very few (if any) symptoms. Within a month or two after infection, they may experience a flu-like illness:FeverHeadacheTirednessEnlarged lymph nodes in the neck and groin areaThese symptoms usually disappear within a week to a month and are often mistaken for another viral infection, such as the flu.
12 Later Symptoms:Rapid weight lossRecurring fever or profuse night sweatsExtreme and unexplained tirednessProlonged swelling of the lymph glands in the armpits, groin, or neckDiarrhea that lasts for more than a weekSores of the mouth, anus, or genitalsPneumoniaRed, brown, pink, or purplish blotches on or under the skin or inside the mouth, nose, or eyelidsMemory loss, depression, and other neurologic disorders

15 Sexual activity with an infected person ABSTINENCE is the only 100% effective way to prevent HIV infection through sexual transmission.

17 injecting drugs or steroids sharing drug equipment or drug solutionssharing objects used for piercing or tattooingBlood Transfusion

19 Testing for HIV: HIV antibodies may be found within 6 – 12 weeks after infected with HIV.In rare cases up to 6 months, for these tests to be accurate.
20 2 tests given to test for HIV are: ElisaTestWesternBlot Test
21 When Should I get Tested for HIV? You should be tested for HIV if you have…had sexual intercourse (vaginal, oral, or anal) without a condomlearned that a partner was not monogamoushave been sexually assaultedhad a condom breakshared needles or syringes to inject drugs (including steroids) or for body piercing, tattooing, or any other reasonhad multiple sexual partnersfound out that a partner has shared needleslearned that a past or current partner is HIV-positivediscovered that a partner has been exposed to HIVhad a recent diagnosis of another sexually transmitted infection (STI)are pregnant
24 process allowing people with HIV to live longer, Even though there isno cure,ARV drugs can slowdown the replicationprocess allowing peoplewith HIV to live longer,healthier lives than thosewho are infected withHIV who are not taking ARV drugs.Video on picture
25 AZT is the most common drug used These drugs ANTIRETROVIRAL (ARV) DRUGS:Today there are over 31 FDA approved antiretroviral (ARV) drugs to treat HIV/AIDS.These drugsDO NOT cure people with HIV/AIDS, they just suppress the virus.AZTis the most commondrug used
26 It VERY important to remember that people infected with HIV who are on ARV drugs can STILL TRANSMIT HIV to others!
