include 10% or less of the population at-risk and 50% or less of the study period, respectively. In addition, each candidate must contain at least 5 cases and have a minimum duration of 2 days. This parameterization is consistent with previous analyses of COVID-19 within the contiguous ...

such as people returning to care homes after illness, People continuing to be infectious after ten days could pose a serious public health risk. We may need to ensure people in those setting have a negative activevirustest to ensure people are no longer infectious. We now want to conduct lar...
