Hawaii health officials say the statewide outbreak of mumps has ended.

The state Department of Health says more than 1000 people were identified with mumps since the outbreak began in March 2017, stemming from two clusters of cases involving nine people on Oahu.

State epidemiologist Sarah Park says no new cases have been confirmed in the last 50 days. The timeframe is double the maximum incubation period for the virus.

According to the department, symptoms of the contagious disease include fever, headache and swelling of the salivary glands, resulting in a swollen jaw. It can also cause complications leading to meningitis, brain swelling or deafness.

According to the Centers for Disease Control and Prevention, the number of U.S. mumps cases increased significantly to more than 6,000 from 2016 to 2017.
