Q

Stage 2: Latent Period

A

CD4 t-lymp cound is 200-499
no aids defining conditions
symptoms occur but not those related to AIDS

17
Q

Stage 3: AIDS phase

A
18
Q

viral load tests measure plasma

A

HIV RNA levels

19
Q

GI manifestations: opportunistic infections in HIV patients

A

Thrush and cytomegalovirus

both present with s/s of painful swallowing, retrosternal pain, inability to swallow and dehyration

20
Q

HAART

A

highly active antiretrivrial therapy

Not a cure, but it is treatment for lie.

Goal is to sustain suppression of HIV replication resulting in undetectable viral load and increasing CD4 cell count to slow progression of AIDS

21

A

RNA. HIV IS A RETROVIRUS

33
Q

Stage 1

A
CD4 t-lymph count is  greater than 500. no aids defining condition
Window period
Test negative for antibodies
viral load high but and very infectious
fever, fatigue, rash for 1-2 weeks
34
Q

Stage 2: Latent Period

A

CD4 t-lymp cound is 200-499
no aids defining conditions
symptoms occur but not those related to AIDS

35
Q

Stage 3: AIDS phase
