ABSTRACT=Various literature cited suggests that bismuth may have usefulness against Covid-19 both in vitro and in vivo.  During the course of caring for Covid-19 patients we administered bismuth subsalicylate to those who displayed diarrhea and/or gastric complaints.  Using relatively conservative criteria, we noted marked improvement in oxygen requirements in most of the cases.  This improvement was observed even when prior therapy with standard anti-Covid drugs had failed.  Our overall impression is that these positive results support a detailed evaluation of bismuth as an adjunct treatment for the treatment of Covid-19.
