evidence_1: here, we combine empirical observations of sars-cov and sars-cov-2 transmission and extreme value statistics to show that the distribution of secondary cases is consistent with being fat-tailed, implying that large superspreading events are extremal, yet probable, occurrences.", "sars-cov and sars-cov-2 sses correspond to fat tails.")
