Before revision:  We find that \sigma_k/\mu_k \gtrsim 3.7 , where \mu_k is the mean infectiousness and \sigma_k is its standard deviation, which implies pervasive superspreading.
After revision:  We find that \sigma_k/\mu_k \gtrsim 3.2 , where \mu_k is the mean infectiousness and \sigma_k is its standard deviation, which implies pervasive superspreading.
