SARS-CoV-2 Infections: An ACE in the Hole and Systems Biology Studies—a Research Agenda

      As of the time of this writing, severe acute respiratory syndrome (SARS) coronavirus (CoV) 2 has involved nearly every country, with almost 6 million identified cases. Of considerable interest has been the evolving information regarding the differential morbidity and mortality caused by this novel virus. Investigators from China have published data suggesting that the population-level case fatality rate in Wuhan was in the 2% to 4% range, whereas outside Wuhan but within China, it was in the 1% range. Even more interesting is that outside China, the case fatality rate has been generally lower—although markedly higher in Italy and among African Americans. Why these differences?
