Infectious Disease Flashcards
retrovirus that targets and destroys CD4 + T cells
HIV
this predicts rate of dz progression in HIV and gauges response to anti retroviral therapy
viral load
Sx of HIV
- Acute: asymptomatic, mono and flu like sxs such as fever, lymphadenopathy, wt loss, headache
- AIDS CD4 count < 200: AIDS defining illness: recurrent infections/malignancies, HIV wasting syndrome (chronic diarrhea + wt loss)
Dx for HIV
- Elisa test: detects anti-HIV antibodies in the blood (can take 6 mos for antibodies to appear)
- Western Blot: confirms dx
