(WWLP) – On this “World Blood Donor Day”, the American Red Cross is making a plea for people to roll up their sleeves and give.

Right now, the Red Cross is experiencing a severe blood shortage. The reason is the number of trauma cases, organ transplants and elective surgeries is rising.

The Red Cross says donors of all blood types, especially type O and those giving platelets, are urged to make an appointment. Hospitals are responding to a high number of traumas and emergency room visits, leading to the need in blood.

“We had a lot of mobile donations that shrunk because of social distancing. What we are going into right now, it sees that hospitals have a greater demand. All those elective surgeries that were postponed in the past year are starting to come back,” said Jeff Hall, Communications Manager for the Red Cross.

In comparison to 2019, the Red Cross has seen demand from trauma centers climb by 10 percent in 2021, more than five times the growth of other facilities that provide blood transfusions.

The Red Cross needs more blood donors to ensure hospitals stay stocked with lifesaving blood products. Those who give blood through June 30, will receive a $5 Amazon gift card by mail.
