A 9-year-old girl with no known underlying health conditions is the youngest person to die from coronavirus complications in Florida, officials said.
Kimora "Kimmie" Lynum died on July 18 in Putnam County, according to Florida Department of Health records. It confirmed her identity and said she's the state's youngest coronavirus fatality.
She had no pre-existing health issues and her mother took her to the hospital due to a high fever, said family spokesman Dejeon Cain. The hospital sent her home and she collapsed a short time later, Cain said.
"She was always happy and made everybody happy. She was phenomenal," said Cain, who's also her cousin.
The family does not know how or where she was infected. She appeared healthy and spent the summer at home, and did not attend school or camp, Cain said.
Kimmie's mother was tested for Covid-19, but had not received her results as of Saturday, Cain said.
