10-year-old boy was bitten by a shark at Daytona Beach Shores Wednesday afternoon, officials said.

(NBC Miami) A 10-year-old boy was bitten by a shark at Daytona Beach Shores Wednesday afternoon, officials said.

The boy, who was visiting from Georgia, suffered minor lacerations after he was bitten on the calf just after 1 p.m., Volusia County Beach Safety Ocean Rescue spokeswoman Tamra Marris said.

He was treated and released at the scene.

The boy was in waist to chest deep water when the incident occurred, Marris said. A lifeguard who was in the area responded.

Marris said the beaches would stay open.

Wednesday's attack was the fourth reported this year in Volusia County, which was labeled the shark bite capital of the world earlier this year by the International Shark Attack File at the Florida Museum of Natural History at the University of Florida.

But while the rate of shark attacks may appear to be on the rise, data suggest that perception reflects better reporting and an increase in the number of people involved in water activities, not an increase in aggressiveness by sharks.

There were 72 reported attacks on humans around the world in 2014, the shark attack center said — three fewer than in 2013.

A 10-year-old boy suffered minor injuries when he was bitten by a shark Wednesday in Daytona Beach Shores, Florida — the second in a week and at least the fourth person to have been attacked by sharks in Volusia County this year, authorities said.

The boy, who wasn't identified, was bitten on the calf as he swam in chest-deep waters just after 1 p.m. ET, said Tamra Marris, a spokeswoman for Volusia County Beach Safety/Ocean Rescue. A lifeguard responded, and the boy was treated at the scene for lacerations on his leg without having to go to a hospital.

The beach safety agency told NBC station WESH of Orlando that beaches would remain open.
