Thursday, June 19th is an important day for celebration and awareness. It marks Juneteenth, our newest federal holiday and a day of reflection and pride that commemorates the ending of slavery in the United States.

It’s also World Sickle Day, established by the United Nations in 2008 and commemorated every June 19th to increase awareness about sickle cell disease – the most common genetic disorder in the U.S. An estimated 100,000 people in the U.S. are living with sickle cell disease, most of whom are of African or Latino descent.

Sickle cell disease causes red blood cells to be hard and crescent-shaped – like a sickle – instead of soft and round, making it difficult for blood to flow smoothly and carry oxygen adequately to the rest of the body. Sickle cell warriors can experience complications like severe pain, anemia, infections, stroke and organ damage.

Blood transfusions help relieve sickle cell disease symptoms by increasing the number of healthy red blood cells in the body, helping to deliver oxygen throughout the body and unblocking blood vessels. But ensuring hospitals have an adequate supply of the major blood types – O, A, B and AB – is only part of the equation.

There are more than 600 known antigens – substances on red blood cells that help determine your blood type – some of which are unique to specific racial and ethnic groups.  Individuals who require regular blood transfusions, like those with sickle cell disease, need blood that is matched more closely to reduce possible complications. Therefore, a sickle warrior is more likely to find a compatible blood match from a donor of the same race or similar ethnic group.

The Red Cross is committed to maintaining a diverse blood supply so patients have access to the right blood at the right time. Check out the links below to learn more about the American Red Cross Sickle Cell Initiative.
