Viral load and CD4 count following HIV seroconversion. Only measurements taken prior to initiation of ART are depicted. Viral load (log₁₀ copies/ ml) is plotted against time since seroconversion (years) in the left panels. No viral load measurements taken for five singly infected individuals. CD4 count is plotted against time since seroconversion (years) in the right hand panels. CD4 measurements were not available for one singly infected individual; for a further 3 singly infected individuals, CD4 measurements were not available prior to initiation of ART. S = singly infected individuals; M = multiple infected individuals.
