A 7-year-old girl from Denver died on Sunday after suffering from flu symptoms at the end of December.
Selina Nguyen was admitted to Aurora Children's Hospital in Aurora shortly before Christmas. She had symptoms of flu and a strong fever.
She has since been in a coma, Fox reported 31.

In mid-January, a friend of Selina's family told KMGH that despite the hospital's efforts, the girl "did not look good."
"Since then Selina has been in the Children's Hospital [she was admitted] Without brain activity, and they have performed some surgery, but it only partially exhales on its own, "said Berkleigh Warren at the time.
Selina's family finally decided to end support on Sunday, a friend of the family confirmed.
Warren's company also set up a GoFundMe site to cover the family's funeral expenses, with additional funds donated to charity.
Selina did not receive a flu shot this year, Fox reports.
FLU SYMPTOMS AND PREVENTION: WHAT YOU NEED TO KNOW
The death of the girl in Colorado is due to the death of four-year-old Ashanti Grinage, who died in early February after a flu illness.
According to Centers for Disease Control and Prevention, nearly 5,800 flu-related hospitalizations have occurred since October 1. The highest hospitalization rate has been reported in adults over 65 and in children under 5 years of age for the 2018-2019 season.
Doctors and health officials continue to emphasize that the flu vaccine is the first line of defense against the virus and can reduce the severity of the disease. The virus typically causes fever, cough, sore throat, runny or stuffy nose, muscle or body aches, headache, fatigue, vomiting and diarrhea. While most people recover from the flu without requiring hospitalization, some may develop life-threatening complications.
