Blood donation situation in the United States
Blood donations in the United States are not volunteers. Therefore, there are many cases where homeless people and other people without money donate blood more than necessary and become unhealthy . Also, in such cases, the tests are sloppy and problems often occur on the side that accepts blood, and a vicious cycle is currently occurring, such as the need for more blood, the need for blood, and the homeless.
Recently, due to the spread of the new coronavirus infection, facilities such as libraries and schools where blood donations were supposed to be donated have been closed , resulting in an unprecedented blood shortage,we have fallen into.
