HIV strands for

Human
Immunodeficiency
Virus

2

what is HIV?

HIV is a retrovirus that attacks the immune system.

3

What is converted in HIV during replications?

Over time the body loses it's ability to do what?

Its genetic material, RNA, must be converted in to DNA during replication.
Over time, the immune system and the body loses its ability to fight the virus.

4

What cells coordinate a body's immune response to an invader?

The CD4 cells coordinate a body’s immune response to an invader (bacteria, virus, etc.)

5

what happens when HIV enters the CD4 cells for reproduction?

it kills the CD4 cells and body's immune system works even harder to make more CDS4 cells

Over time HIV destroys the CD4 cells faster than the immune system can make new ones

HIV damages the very system that usually protects the body from infection

6

Course of HIV treatment

Virus can be transmitted during each stage

SEROCONVERSION
Infection, develop antibodies
ASYMPTOMATIC
No signs or symptoms of HIV
Immune system controls virus production
SYMPTOMATIC
Physical signs of HIV infection
Some immune suppression
AIDS
Opportunistic infections
End-stage disease

7

Infection, develop antibodies

SEROCONVERSION

8

No signs or symptoms of HIV
Immune system controls virus production

ASYMPTOMATIC

9

Physical signs of HIV infection
Some immune suppression

SYMPTOMATIC

10

Opportunistic infections
End-stage disease

AIDS

11

oppurtuniest infections

take advantage of a weakened immune system to cause more frequent or severe illness

CDC identifies 29 infections
Prophylactic drugs may be given to prevent illness for some conditions

12

clinical oppurtuniest infections options

Effective ART
Vaccination
Avoiding exposure to certain pathogens
Disease treatment
Preventing disease recurrence (secondary prophylaxis or chronic maintenance therapy)

13

Recommended for all HIV-positive people
To prevent disease progression
To prevent transmission of infections
Strength of recommendation based on
CD4 count
Transmission risk

antiretrovial therapy

14

Suppress the HIV virus, prevent transmissions of it

this therapy changes HIV from a terminal (fatal) disease to a “chronic disease”

antiretrovial therapy

15

ARVs change HIV from a terminal (fatal) disease to a

“chronic disease”

16

how do ARVs control HIV?

ARVs reduce the ability of the HIV virus to replicate

In turn, this increases the ability of the body to fight disease

Reduces the risk of HIV transmission

17

HIV as an Episodic Disability

Marked by fluctuating periods and degrees of wellness and illness
Unpredictable

Other episodic disabilities include: some forms of mental illness, HIV/AIDS, MS, diabetes, arthritis, and some cancer

Presents challenges for active labour force participation, insurance benefits, income security, and social inclusion
