Twenty-five sailors and Marines on a U.S. warship contracted parotitis, forcing the ship to remain quarantined at sea for more than two months, according to CNN.
Parotitis is a viral infection similar to mumps. The first infection on USS Fort McHenry occurred in December. The most recent case was reported March 9.
"None of the cases are life-threatening, and all have either already made or are expected to make a full recovery," the United States' Fifth Fleet said in a statement to CNN.
The warship houses 703 military personnel, all of whom received the mumps, measles and rubella vaccine. Since the initial case was detected on the warship in December, 24 of the 25 sickened individuals have recovered and resumed their duties, according to the report.
The ship is currently stationed in the Persian Gulf region, and military officials are deciding whether it is medically safe for the ship to make a port call. During large disease outbreaks, the military often delays port visits until 30 days after the last illness is reported, a military official told CNN.
