Author Correction: In vitro virucidal activity of Echinaforce® an Echinacea purpurea preparation against coronaviruses including common cold coronavirus 229E and SARS-CoV-2

摘要

No virucidal activity against four human coronaviruses and Yellow Fever Virus is observed after direct contact with 0.2% ethanol in suspension. No significant difference in viral replication of viruses previously shown to be sensitive to Ecinaforce® was observed after treatment with 0.2% ethanol, the residual ethanol concentration corresponding to treatment with 50 µg/mL Echinaforce®. These data are generated from two independent experiments in triplicate or duplicate (HCoV-229E) and reported as mean ± sd or geometric mean ± geometric sd (SARS-CoV-2). LOD: limit of detection (10 TCID50), n.d: not detected (assigned value: 3.16 TCID50/mL)
