WHAT IS HIV & AIDS
Human Immunodeficiency Virus (HIV) Virus that damages the body's defense system,
stopping it from effectively fighting infections. The virus lives in certain body fluids, such as
blood, semen, and vaginal fluids.
Acquired Immune Deficiency Syndrome (AIDS) A person has developed AIDS when they are
affected by certain infections and cancers because their body's defenses are weakened.
WHAT IS THE DIFFERENCE BETWEEN HIV AND AIDS
Human Immunodeficiency Virus (HIV)
Acquired Immune Deficiency Syndrome (AIDS)
HIV is the virus which attacks the T-cells in the immune system.
AIDS is the syndrome which appears in advanced stages of HIV infection.
HIV is a virus. AIDS is a medical condition.
HISTORY OF AIDS
First appearing in the Democratic Republic of the Congo in 1959.
AIDS arrived in the United States in 1981.
The HIV virus was discovered in 1983.
The cocktail first became available in 1995, contributing to a significant decrease in AIDS deaths in the Western world.
History of AIDS from beginning 1981 to 2012.
LIFE CYCLE OF AIDS
HIV can infect multiple cells in your body.
Including brain cells, but its main target is the CD4
lymphocyte, also called a T-cell or CD4 cell.
A CD4 cell is infected with HIV, the virus goes
through multiple steps to reproduce itself and create
many more virus particles.
LIFE CYCLE OF AIDS
LIFE CYCLE OF AIDS
The life cycle process of aids is broken up into the following steps.
Binding and Fusion Reverse Transcription Transcription Assembly Budding These steps of the life-cycle of HIV are important to
know because the medications used to control HIV infection act to interrupt this replication cycle
LIFE CYCLE OF AIDS
CAUSING OF AIDS
The disease progresses in the absence of antiretroviral therapy.
The rate of disease progression varies widely between individuals and depends on many factors.
CAUSING OF AIDS
Factors of
AIDS Progres
sion
Age of the patient
Body's ability to defend against HIV/AIDS
Access to health care
Existence of coexisting infections
The infected person's genetic inheritance
CAUSING OF AIDS
HIV/AIDS can be transmitted through:
Sexual transmission Prenatal transmission Blood transmission By sharing unsterilized
needles, syringes, and other injecting equipment
By artificial insemination with HIV infected semen
MISCONCEPTIONS ABOUT HIV /AIDS
The virus CANNOT be transmitted from:
Shaking hands Sneezing Touching unbroken skin Using the same toilet Sharing towels Sharing cutlery Mouth-to-mouth resuscitation Other forms of "casual contact"
SIGNS AND SYMPTOMS OF HIV/AIDS
The symptoms of HIV are the result of infections caused by bacteria, viruses, fungi and parasites.
Signs and symptoms of early HIV infection
Asymptomatic HIV infection
Late-stage HIV infection
SIGNS AND SYMPTOMS OF HIV/AIDS
Signs and symptoms of early HIV infectionSymptoms of early HIV infection may include:
Fever Chills Joint pain Muscle ache Sore throat Sweats (particularly at night) Enlarged glands A red rash Tiredness Weakness Weight loss
SIGNS AND SYMPTOMS OF HIV/AIDS
Asymptomatic HIV/AIDS Infection In many cases, after the initial symptoms disappear,
there will not be any further symptoms for many years.
During this time, the virus carries on developing and damages the immune system.
This process can take up to 10 years. The infected person will experience no symptoms,
feel well and appear healthy.
SIGNS AND SYMPTOMS OF HIV/AIDS
Late-stage HIV/AIDS Infection
Signs and symptoms of late-stage HIV infection may include: Blurred vision Diarrhea, which is usually persistent or
chronic Dry cough Fever of above 37C (100F) lasting for weeks Night sweats Permanent tiredness Shortness of breath Swollen glands lasting for weeks Weight loss White spots on the tongue or mouth
PRECAUTIONS OF AIDS
Unprotected Sex Drug abuse and
needle sharing Body fluid exposure Pregnancy Education
MANAGING HIV/AIDS Adherence General Health Additional precautions Long-term condition Psychological
