HIV/AIDS Lauren Davidson
Human Immunodeficiency Virus • Commonly know as HIV • Attacks the immune system • Destroys CD4+ T cells • Transmitted through direct contact with infected bodily fluids • Blood • Semen, pre-seminal fluid • Rectal fluids • Vaginal fluids • Breast milk
Stages of HIV • Acute Infection • Clinical Latency • Acquired Immunodeficiency Syndrome • AIDS
1. Acute Infection • Within 2 to 4 weeks after infection with HIV • Acute retroviral syndrome (ARS): flu-like symptoms • Primary HIV infection • Possible to show no symptoms • Greatest chance to spread HIV
2. Clinical Latency • Asymptomatic/Chronic HIV infection • Virus reproduces within the body at slower rates • Still possible to spread virus
3. Acquired Immunodeficiency Syndrome • AIDS- final stage of infection • Body is vulnerable to infections and infection-related cancers • Opportunistic illnesses • Diagnosis: • CD4+ cells < 200 cells/mm3 • Develop one or more opportunistic illnesses
HIV/AIDS in the us • First reported in the United States: • HIV: mid-late 1970’s • AIDS: 1981 • Since 1981, more than 980,000 cases of AIDS have been reported • Over 1,000,000 Americans are infected with HIV • ¼ are unaware of infection
HIV/aids in the us • About 50,000 people get infected with HIV each year • In 2010, about 15,500 people with AIDS died in the United States • More than 635,000 individuals with AIDS in the United States have died
Transmission • Having sex without a condom • Sharing needles • Pregnancy, child birth, breast feeding • 25% chance
Risk factors Gender Racial/Ethnicity Risky Behavior Age
Complications Common infections Other complications Cancer: Kaposi's sarcoma tumor of the blood vessel walls Lymphoma Wasting syndrome Dementia Kidney disease • Tuberculosis (TB) • Salmonellosis. • Cytomegalovirus (CMV • Candidiasis • “Thrush” • Cryptococcal meningitis • Toxoplasmosis • Cryptosporidiosis
treatment • HIV/AIDS is not curable • Only treatable • 31 antiretroviral drugs (ARVs) • Suppress virus replication • Medication regimen • Several drugs, several times a day • “Medical cocktail” • Adherence is crucial
Prevention Reduce the risk of contracting or transmitting HIV: Do not share needles Use male or female condoms • Get tested regularly • Practice abstinence • Remain faithful to spouse/ partner
Stress • Psychosocial factors play an important role in progression of HIV infection, its morbidity and mortality: • Stressful life events • Depression • Denial/Avoidance coping • Negative expectations • Lack of social support • ARV treatment helps to reduce impact of stress
