1 Human Immunodeficiency Virus
HIV Human Immunodeficiency Virus

2 Human Immunodeficiency Virus
HIV Defined Human Immunodeficiency Virus HIV attacks specific cells of the immune system, disabling the body’s defenses against other pathogens. HIV infects helper T cells which are responsible for stimulating other cells of the immune system to produce antibodies against invading pathogens.

3 HIV Transmission 4 Fluids that can transmit the virus Blood Semen
Vaginal Fluids Breast Milk

4 Transmission Routes Body Openings Genitals Anus Mouth Opening of skin

5 HIV is usually transmitted by:
Sexual contact that involves contact with an infected persons’ body fluids (vaginal secretions, semen, blood) through vaginal, oral, and anal sex. Sharing needles with an infected person (IV drugs, steroids, injecting vitamins, tattooing) Mother to baby During pregnancy mother can infect unborn baby in the womb, during the birth process, or breast milk of infected mother Contact with infected blood into a cut or sore

6 HIV Testing Test confidentially or anonymously
Positive test result= presence of HIV antibodies Antibodies usually develop within 3 months but can take up to 6 months (6 month window period) Positive test means: You are infected with HIV You will always have HIV You can infect others

7 Stages of HIV Infection
Asymptomatic Stage: “lack of symptoms” Most people don’t experience symptoms until 7-10 years after infected and they may feel fine. People can still infect others in this stage.

8 Symptomatic Stage This stage is marked by a person feeling symptoms.
Symptoms may include: Persistent diarrhea Persistent fever Fungal infections Fatigue Swollen lymph nodes Rashes Sore throat

9 AIDS Stage AIDS = Acquired Immunodeficiency Disease
Is marked by a very low number of T cells. The average number for a healthy person is AIDS is defined at a T cell count under 200. At this point a person’s immune system is extremely low and more susceptible to infection. Opportunistic infections are infections that take advantage of a weak immune system and is what ultimately causes death of an AIDS patient.

10 AIDS SYMPTOMS Coughing and shortness of breath
Seizures and lack of coordination Difficult or painful swallowing Mental symptoms such as confusion and forgetfulness Severe or persistent diarrhea Vision loss Various cancer Severe headaches Coma Extreme fatigue

11 HIV Will Lead to AIDS and ultimately cause death
A person may move out of the AIDS stage if T cells raise but will never be HIV free

12 How to Prevent Transmission
Practice Abstinence Avoid Drugs Avoid contact with blood or body fluids Sexual fidelity in marriage / monogamous relationship Barrier protection (latex condoms)
