'Overcomer': 4-year-old's inspiring video reaches millions

Leah Carroll’s inspiring words and adorable shoulder shimmy have been viewed more than 37 million times on social media, where a legion of followers have been sending good wishes and prayers to the 4-year-old who is battling a rare blood disorder.

Leah, of Oakland, California, was diagnosed with severe congenital neutropenia, which causes a shortage of white blood cells and leaves patients susceptible to infection. She underwent a bone marrow transplant on Feb. 7, 2014 and another on March 29, 2016.

According to a March 28 post on the Prayers and Love for Leah page by her mother, Lindsay Chapman-Carroll, she is currently dealing with an infection and a flare up of graft-versus-host disease, but a recent bone marrow aspiration showed 100 percent donor cells.

Chapman-Carroll regularly posts videos and updates on her daughter’s health, including the Feb. 5 clip that went viral, featuring Leah singing and dancing to the gospel hit “Overcomer.” 

“You may feel down for a moment, feel like it’s hopeless that’s when he reminds you, that you’re an overcomer,” Carroll sings in the video.

“The world just needed some joy right now, especially in the United States,” Chapman-Carroll told CBS News. “And I think Leah has this pure joy about her.”

Carroll’s doctor told CBS News that her disorder is close to being cured.
