HIVHumanImmunodeficiency Virus

AIDSAcquired ImmunodeficiencySyndrome

Cells & chemicals protect the body against disease. Ex: White blood cells

T-Cells

Antibodies (ATB)

-Substance formedresponse to a disease

or vaccine.-made by immune

system-usually protects

against diseaseEx.- chicken pox

hepatitis B

Antigens

- Made by body in response to exposure of disease or foreign body stimulating the immune system to start working.

- Generally indicates active disease

After exposure- flu like symptoms develop

↓ HIV antibodies develop 6-12 weeks later –

window period↓

May not have any symptoms for 5-10 years- incubation period

↓ Develops AIDS

Window period- 6-12 weeks develop ATB

Incubation period- 5-10 years until you show symptoms

HIV attacks body defenses↓

Damages cells of immune system↓

Immune system can’t function↓

Virus multiplies- 1 week after exposures flu s/sx (last about 1 wk.) then go away

↓

6-12 weeks- no symptoms no symptoms window period

↓5-10 years –incubation period-AIDS

destroying immune system↓

Symptoms occur

Fever Fatigue Diarrhea Skin rashes Night sweats Loss of appetite Swollen lymph nodes Significant wgt loss

Dry cough, shortness of breath (SOB)

Memory loss

Furry white spots in mouth

Red purple spots on skin-skin, mouth, lung

Type of cancer common in AIDs pt.

Low resistance in infection- get infections we normally fight off

Infection takes over body b/c the immune system can’t stop it & it grows out of control

Ex.-

Other examples: thrush, yeast infection

-Pneumonia caused by germ that lives in lungs

- Leading cause of death in AIDS pt.

Positive illness ( kaposi sarcoma, pneumocystis carni)

++ HIV test

+↓ White Blood cell count/T-cells

Lives outside body a few hours Dead once fluid is dried Hepatitis lives outside the body for 8

hours (even in dried secretions) To infect a person virus must get inside

the body

1 part bleach + 10 part water
