An 11-year-old Norwood boy who died after falling ill at a camp in Pennsylvania had meningitis, according to the Pennsylvania Health Department.

The department says that Daniel Beer tested positive for a bacterial form of meningitis. The disease can lead to inflammation of the brain and spinal cord and can be fatal.

Beer was staying at Camp Nah-Jee-Wah in Milford, Pennsylvania, when he started to complain of severe stomach pain. He died at the hospital Monday.

Three other boys staying in the cabin also showed signs of stomach illnesses but were released from the hospital.

An email sent to parents by NJY Camps said that the boy had contracted Neisseria meningitidis, a bacteria that can cause meningitis and sepsis.
