With recommendations to stay home during the COVID-19 pandemic, the U.S. now has a critical blood shortage. Blood donation collections have plummeted due to canceled blood drives and concerns about being out in the community. Almost half of U.S. blood collectors are reporting that they only have a two-day supply or less of blood products.
