A Look at Shark Attacks Reported So Far This Summer in the US

— -- Beachgoers beware this Fourth of July weekend as the number of shark attacks across parts of the East Coast has reached unprecedented levels.

Less than two weeks into summer, a string of shark attacks have already been reported down the East Coast, from North Carolina to Florida.

Here are some of the shark attacks reported so far:

May 29 in New Smyrna, Florida:

On May 29, a shark bit a 19-year-old woman on the foot while she was in waist-deep water in New Smyrna, Florida, according to Volusia County Beach Safety Ocean Rescue.

The injury was minor and the woman was treated on site, ABC affiliate WFTV reported.

May 29 in Cocoa Beach, Florida:

The same day, a 14-year-old girl vacationing from Ohio was bit on the foot near the International Palms Resort in Cocoa Beach, Florida, authorities said.

The girl alerted the lifeguard and was taken to a local hospital, where she was treated, according to authorities.

June 11 in Ocean Isle Beach, North Carolina:

A 13-year-old girl was injured after a shark bit her and her boogie board on June 11 in Ocean Isle Beach, North Carolina, according to the town's mayor.

The teen suffered lacerations on her foot, but was not severely injured, Mayor Debbie Smith told ABC affiliate WWAY.

"It got a hold of her foot and bit her board in half," the caller says on an audio recording of the 911 call obtained by ABC News.

The shark was reported to be about 4 feet long, according to WWAY.

June 14 in Oak Island, North Carolina:

Three days later, on June 14, Kiersten Yow, 12, was attacked by a shark in Oak Island, North Carolina.

She lost part of her left arm and suffered severe injuries to her left leg, according to a statement on a gofundme page created to raise money for her medical bills.

Despite the serious injuries, she is expected to keep her leg, according to the gofundme page, which also states Yow “has a long road to recovery that will include surgeries and rehabilitation.”

June 14 in Oak Island, North Carolina:

Less than 90 minutes after Kiersten was bit, Hunter Treschl, 16, lost his arm in an attack just a few miles away.

The high school junior said he was in waist-high water for about one minute when the shark attacked.

“I saw the shark on my left arm,” he said. “It was half way up my bicep, kind of. It just attached and then it wasn’t attached anymore.”

Treschl was dragged to the shore by his cousin and then saved by fellow beachgoers who used everything they could find on the beach to help stop the bleeding.

Treschl was eventually transported to a local hospital and had his left arm amputated below the shoulder.

“It all happened very, very quickly,” Hunter told ABC News.

“I’m thinking, ‘There’s no way this just happened, because there’s no pain,’” he said. “I didn’t feel anything.”

June 17 in Daytona Beach Shores, Florida:

A 10-year-old boy was swimming in shallow water in Daytona Beach Shores, Florida, when he was bitten by what appeared to be a small shark, according to Capt. Tamra Marris of Volusia County Beach Safety Ocean Rescue.

The boy suffered minor lacerations to his calf. He was treated and released at the scene, Marris said.

June 24 in Surf City, North Carolina:

An 8-year-old boy was in Surf City, North Carolina, when he suffered "minor leg and foot injuries" from what appeared to be a "small shark bite," the Surf City Police Department told ABC News.

"The wounds were superficial and not considered serious," police said, "but Surf City Police and Pender East EMS responded and provided on scene treatment."

The child's parents took him to have the bite further assessed at Scott's Hill Emergency Room, police said.

June 25 in Outer Banks, North Carolina:

The following day, on June 25, an 18-year-old was bit by a shark near Waves in Dare County, part of North Carolina's Outer Banks, authorities said.

He was hospitalized in critical condition and later upgraded to serious condition, said an official from Sentara Norfolk General Hospital in Norfolk, Virginia.

June 26 in Avon, North Carolina:

A day after the Out Banks attack, Patrick Thornton was at Avon Beach, North Carolina, with his family when a 5-foot shark tugged at his foot, he said.

“It took a pretty big chunk out of my right leg, so I started punching the shark, and then it grabbed my back and must have bit me in the back,” said Thornton, 47.

Thornton said he managed to get the shark off of him. His niece and nephew, located nearby, made it to shore. But his son Jack stayed in the water, paralyzed with fear, Thornton said.

“I ran over and grabbed Jack, and as I was bringing him to the shore, the shark came and bit me again in the back, and this time he bit me really, really hard,” Thornton said.

Thornton said he punched the shark again. Finally, it swam off.

Once on shore, Thornton was rushed to the hospital, suffering wounds to his right leg and deep punctures in his back.

June 30, 2015 in Isle of Palms, South Carolina:

A teenage boy was bitten on his leg by a shark on the evening of June 30 in Isle of Palms, South Carolina, authorities said.

He suffered non-life-threatening injuries, according to Isle of Palms Fire Chief Ann Graham.

“It was a pretty big bite -- but it didn’t do any tearing,” she told ABC News.

“He’s lucky it's not a whole lot worse -- he’ll have a story to tell,” Graham said.

July 1 in Ocracoke Island, North Carolina:

Andrew Costello, 68, was bitten by a shark off the coast of Ocracoke Island, North Carolina. He was bitten on his left side in his lower leg and hip and on both his hands, Hyde County EMS Director Justin Gibbs told ABC News.

Costello "had been swimming in about 25-30 feet offshore in about waist-deep water" at the time of the attack, the National Park Service said in a statement.

Costello was taken to Vidant Medical Center in Greenville, North Carolina, in fair condition Wednesday, the hospital said. Thursday he was upgraded to good condition, the hospital said.

Costello called the attack "frightening and painful" in a statement Thursday, adding that he feels "very fortunate to have survived."

Costello will need several operations, Dr. Eric Toschlog, Chief of Trauma and Acute Care Surgery at Vidant Medical Center, said in a statement Thursday.

"We are optimistic that he will make a full recovery," Toschlog said.

With so many of the attacks along the North Carolina coast, some law enforcement officials are calling for some of the waterfront communities to consider closing their beaches.

Sarah Johnson, Public Information Officer for Hyde County, North Carolina, told ABC News that, while Hyde County has no control over beach patrol or staffing, the EMS presence at Ocracoke Island will be increased slightly this 4th of July weekend.

North Carolina's Cape Hatteras National Park Service will add extra beach patrol rangers this weekend who will warn beach-goers of the dangers, Cyndy Holda, public affairs specialist at the National Park Service, told ABC News.

While there won't be extra surveillance in the water, Hold said, there will be "strong encouragement to not stray from the shore" for those who do go in the water.
