Justin Anthony told CNN that Emma was diagnosed with pneumonia on March 15 and tested positive for coronavirus Friday night. As of Saturday, she was on a fan and is currently in stable condition, Anthony said.
Emma had no existing relationship. She hasn't traveled recently, and it's unknown how she infected the virus, according to Anthony.
Children's Healthcare of Atlanta-Scottish Rite Hospital confirmed that a current patient tested positive for Covid-19, although it refused to go any further.
"The patient remains isolated, and we have consistently applied appropriate precautions. Further details will not be released due to privacy laws," said hospital spokeswoman Jessica Pope.
Of nearly 45,000 confirmed cases in China up to and including February 11, there was only one death in anyone younger than 20, according to the Chinese Center for Disease Control and Prevention, and no deaths among children younger than 10 years.
Of 731 confirmed and 1,412 suspected cases of Covid-19 in children in China, one child, a 14-year-old boy, died, according to a new study that will be published in the journal Pediatrics in June. Moreover, almost 6% of children's cases were severe, compared to 18.5% of adults who had severe symptoms, the study found.
Young adults have better outcomes than older ones, but also they are not immune to the virus.
Anthony told CNN he has Emma's mother's approval to tell her story. He said he wants people to know the severity of the coronavirus.
"I know first hand how dangerous it is," he said. "Everyone goes on to say & # 39; it doesn't affect younger people. & # 39; But here's a 12-year-old fighting for her life. People need to practice social distancing. People need to take care of their children. People need to take this seriously. "
