We thought B.1.1.7's increased infectiousness was due to higher viral load. New data from @NBA players and staff, with frequent sampling, suggests it's related to delayed clearance, longer duration of infections dash.harvard.edu/handle/1/37366… @StephenKissler @yhgrad and colleagues pic.twitter.com/T352viTcxp

Variant B.1.1.7 may cause longer infections with similar peak viral loads to non-B.1.1.7 SARS-CoV-2. This may explain its increased transmissibility. It may also require rethinking isolation duration, no? dash.harvard.edu/handle/1/37366…

Infections in people with B.1.1.7 lasted an average of 13.3 days, compared with 8.2 days with other variants. B.1.1.7 may be more easily transmitted due to longer infection and more opportunity to infect others, suggesting a need for longer quarantine. bit.ly/3qUhE9F

Regular sampling required to understand viral load dynamics of CoV2, as in this study of B1117, finding longer (not ⬆️) VL peak. As others have said this may explain ⬆️ infectiousness.
