Liver transplantation during COVID-19: Adaptive measures with future significance

Figure 1 Number of adult liver transplants performed in the United States between January 1, 2020, and April 1, 2022 (data from the United Network for Organ Sharing database). The number of liver transplants performed during the course of the coronavirus disease 2019 pandemic. An initial decrease in the Spring of 2020 was countered with a series of measures, that restored the number of transplants by the Summer of 2020. With each consecutive wave, primarily during the winter months, there were fewer adult liver transplants.
