What are HIV & AIDS?


HIV & AIDS attack the blood stream.
To learn more about what happens, lets
first look at what our blood consists of.
Red Blood Cells




Use Hemoglobin to carry oxygen.
5.2x106 per cubic millimeter of blood
Carry 300% more oxygen than plasma
Carries CO2 and waste away from
tissue.
White Blood Cells









Types of WBCs
Neutrophils
Eosinophils
Basophiles
Monocytes
Helper T cells **
Cytotoxic T cells
Memory T cells
Suppressor T cells
Is HIV and AIDS the same
thing?
HIV




“Human Immunodeficiency Syndrome”
A specific type of virus (a retrovirus)
HIV invades the helper T cells to
replicate itself.
No Cure
AIDS

Acquired Immunodeficiency Syndrome

HIV is the virus that causes AIDS



Disease limits the body’s ability to fight
infection
A person with AIDS has a very weak
immune system
No Cure
New HIV Infections in
2002 by Age Group
Four Stages of HIV
Stage 1 - Primary

Short, flu-like illness - occurs one to six
weeks after infection

no symptoms at all

Infected person can infect other people
Stage 2 - Asymptomatic

Lasts for an average of ten years

This stage is free from symptoms

There may be swollen glands


The level of HIV in the blood drops to very
low levels
HIV antibodies are detectable in the blood
Stage 3 - Symptomatic

The symptoms are mild

The immune system deteriorates

emergence of opportunistic infections
and cancers
Stage 4 - HIV  AIDS


The immune
system weakens
The illnesses
become more
severe leading to
an AIDS diagnosis
Modes of HIV/AIDS
Transmission
Through Bodily Fluids

Blood products

Semen

Vaginal fluids

Breast Milk
Through IV Drug Use

Sharing Needles


Without sterilization
Increases the chances of contracting HIV
Four ways to protect yourself?




Abstinence
Monogamous Relationship
Protected Sex
Sterile needles
Abstinence


It is the only 100 % effective method of
not acquiring HIV/AIDS.
Refraining from intravenous drug use


Blood-borne diseases like HIV/Aids are
spread from one person to another
through the exchange of blood.
At this time, there is no cure for bloodborne pathogens.




Only women can get infected by bloodborne pathogens.
You can’t get infected with a bloodborne pathogen if you are healthy and
strong.
You can tell a person is infected with a
blood borne pathogen by looking at
them.

A person might get a blood-borne disease
by:


Donating blood. 
Using a public toilet. 
Kissing. 
Being bitten by a mosquito. 
Being born to a mother who infected with a
blood-borne pathogen. 

A person might get a blood-borne disease
by:

Sharing needles with another person. 
Using the same water fountain as a person who
is infected with a blood-borne pathogen. 
Swimming in a public pool. 
Shaking hands 
