Teen's Condition Improving After Shark Attack in North Carolina

A teenage boy has been upgraded from critical to serious condition after he was bitten by a shark off the North Carolina coast Saturday, a hospital official said.

The teen was taken to Sentara Norfolk General Hospital in Norfolk, Virginia, after he was attacked Saturday afternoon near Waves in Dare County, part of the Outer Banks.

The teenager, who has not been identified, is 18 years old, Carol Via Flynn of Sentara Healthcare told ABC News today, though the National Park Service previously reported the victim's age as 17.

The attack came a day after a 47-year-old man was bitten by a shark while swimming at a beach in Avon, North Carolina.

Four other attacks were reported along North Carolina's coastline this month. A 13-year-old girl was bitten in the foot at Ocean Isle on June 11. Hunter Treschl, 16, lost his arm in an attack on June 14 at Oak Island, and Kiersten Yow, 12, was bitten in the arm and leg less than 90 minutes before Treschl's attack. An 8-year-old boy was bitten on Wednesday at Surf City.
