Figure 2.

Timeline of reinfection events from the estimated date of primary hepatitis C virus (HCV) infection. Timelines illustrate results of HCV RNA tests and HCV genotyping for the 28 participants with reinfection. Each box represents 1 HCV RNA test. Empty boxes are tests in which HCV RNA was undetectable, whereas filled boxes (black or colored) indicate that HCV RNA was detectable. HCV genotyping results are indicated using color and box labels. Within individuals, distinct strains within a single viral genotype and subtype that were confirmed by viral sequencing are illustrated using different shades of the same color. Reinfection events (R) are defined by the appearance of a new viral genotype, viral subtype, or distinct strain confirmed by viral sequencing following a period during which HCV RNA was undetectable. HCV from the primary infections of participants UFOVT0134 and AUS206 was serotyped.
