What Cell Does HIV Infect????

Helper T Cells

HIV and AIDS

Helper T Cells- White Blood cells that identify pathogens, sound the alarm and start the production of antibodies to protect the body.

As more T cells are destroyed, the immune system weakens and the person gets sick more often.

Opportunistic Infection – pathogens take advantage of the weak immune system

Specific type of pneumonia and cancer

The virus, HIV, will lead to the condition known as AIDS a breakdown of the body’s ability to fight infection.

Acquired – have to do something to get it

Immune – destroys your immune system

Deficiency – lacking your immune system

Syndrome – continues on, does not end

HIV and AIDS

AIDS Information•a breakdown of the body’s ability to fight infection.

•When you have less than 200 T cells you get the diagnosis of AIDS

•Average person typically has between 500 - 1300 T cells/ mm3•Most people are above 700

Victims my have no signs or symptoms for many years.

Some have flu like symptoms within a few weeks of being infected.

They can spread the disease during this time and not know it.

HIV cannot be cured, but people are living 25+ years after being infected.
