Abstract

The clinical manifestation of moderate to severe COVID-19 has parallels to secondary haemophagocytic lymphohistiocytosis (HLH) both clinically and based on molecular inflammatory response. We found no evidence to support the utility of risk stratifying COVID-19 patients using risk scoring methodology designed for HLH.
