Twenty-five out of 703 service members aboard the USS Fort McHenry have been diagnosed with a viral infection similar to the mumps, according to Navy officials.

Officials said sailors and Marines onboard became ill with parotitis while the ship, which is based in Mayport, was overseas in the Middle East on Dec. 22.

There have been no new cases of the infection on the ship since Feb. 27, officials said.

Officials said none of the service members' conditions have been reported as life-threatening.

Twenty-four of the 25 infected sailors have made a full recovery with one sailor still undergoing treatment, according to officials.

Those affected were quarantined and treated in the ship's medical facilities. Areas where the affected lived and worked have been thoroughly cleaned and disinfected, officials said.
