Based on the figure below and information presented in class which of the following is NOT true about HIV and Acquired Immunodeficiency Syndrome? CD4 T cell blood concentration (cells/mm³) 1200 1100 1000 900 800 700 600 500 400 300 200 100 Category A: Asymptomatic or chronic lymphadenopathy 1 1-2 months following initial infection, the population of HIV in blood peaks at about 10,000,000/ml. 3 Seroconversion. HF 1-2 months 2 1-2 months following initial infection, population of CD4 T cells plunges. Antibodies against HIV appear. HIV population blood crashes. -HIV population in blood 1 HIV in blood stabilizes at steady state of 1000 to 10,000/ml. Category B: Symptomatic. Early indications of immune failure 4 5 CD4 T cell population. declines steadily.
