Table 1.
Time since infection | Diagnostic outcome | Infection status in model |
---|---|---|
Week 1 (3–10 dpi) | Virus positive, PCR+ and seronegative | Infectious |
Weeks 2–8 (10–60 dpi) | Virus positive, PCR+ and seropositive | Not infectious and immunea |
Weeks 9–14 (60–100 dpi) | Virus negative, PCR+ and seropositive | Not infectious and immunea |
From week 15 (> 100 dpi) | Virus negative, PCR− and seropositive | Not infectious and immunea |
In the scenario ‘prolonged infectivity of survivors’, the status is infectious in weeks 2–4 followed by recovery.
