We calculated the time between successive infections as the number of days between the last positive test associated with an individual’s first identified infection (i.e., within 89 days of a previous positive test, if any) and the first positive test associated with their suspected subsequent infection (i.e., at least 90 days after the most recent positive test). We analyzed the distribution of these times for all second and third infections, and for the subset of second and third infections occurring since 01 November 2021.
