Document: As a comparison, the Severe Acute Respiratory Syndrome (SARS) coronavirus was notable because infectiousness increased around 7-10 days after illness onset. 5, 6 Once containment measures were effectively implemented, including isolation of cases and quarantine of their close contacts, it was possible to reduce substantially onwards transmission of infection ( Figure 1a) . 7, 8 In contrast, seasonal influenza is characterized by increase in infectiousness shortly around or even before illness onset. 9 For SARS-CoV-2, there remains very limited information to date on the dynamics of contagiousness over time.
