Probability mass function of serial interval of SARS-CoV-2 variant B.1.617.2 cases (A), probability density function of serial interval of cases identified before the partial lockdown on April 7, 2020 (B), and empirical cumulative density function of serial intervals and estimated cumulative density function of serial intervals (C) Most primary cases had known exposure (or exposures) outside the household and secondary cases do not have the same exposure as the primary case thereby allowing the directionality of infection to be identified. Negative serial intervals, which signify pre-symptomatic transmission, were also included in the analysis.
