COVID-19 COMPREHENSIVE RISK INDEX FOR THE UNITED STATES

摘要

As described in the online article, the following risk indicators appear to have more important warning significance and can be used to construct an infectious disease risk index: ? Total infection rate: cases per 100K population ? Total test rate: tests per 100K population ? Active infection rate: active cases per 100K population ? Total positive rate: total positive/test ratio ? New positive rate ? Close contact growth rate ? New confirmed case growth rate ? Case fatality rate ? New death case growth rate Among them, the growth rate of new close contacts is not easy to obtain, because not all countries disclose the number of close contacts, and not every country can fully track close contacts. Therefore, our first version of the COVID-19 comprehensive risk index (Table 1) does not include this indicator for the time being, and other indicators are weighted and averaged according to the following weights.
