Participants reported no change in symptoms or disease duration. Only 0.7% of reports\u00a0 indicated possible reinfection (two positive tests separated by more than 90 days), suggesting that B.1.1.7 reinfections occurred with similar frequency compared to pre-existing variants. Reinfection occurrence also had stronger correlation with an overall regional rise in cases than with a regional increase in the proportion of B.1.1.7 infections as estimated by proportion of tests with Spike-Gene Target Failure. The authors also estimate that although Rt associated with B.1.1.7 was 1.4-times higher than pre-existing variants, B.1.1.7 Rt was reduced below 1 by lockdown measures even in regions with high proportions of B.1.1.7 infections.<\/span><\/li>\n<\/ul>\n<p><i><span style=\"font-weight: 400\">Graham et al.\u00a0(Apr 12, 2021).
