Mumps Outbreak is “Worst in Several Decades for Hawaiʻi”
Mumps, commonly considered a disease that affects only young children, is affecting primarily adults and adolescents in Hawaiʻi, according to new information released today by the state Department of Health.
Adults between the ages of 20 and early 40s and adolescents 10 years old and above make up the majority of Hawaiʻi’s recent mumps cases, according to the Hawaiʻi DOH.
Officials with the Department of Health offered practical ways to avoid getting the disease.
“We strongly recommend getting an outbreak dose of the MMR (measles, mumps, and rubella) vaccine, especially for those who live, work, or socialize regularly in crowded settings,” said Dr. Sarah Park, state epidemiologist and chief of the Disease Outbreak Control Division. “It’s also important to stay home when sick and even consider methods of social distancing, which includes avoiding crowded settings and gatherings, and not hugging or kissing when greeting others.”
“Based on the cases that we have been able to track, the common denomination has been exposure to some type of gathering, whether school, work, church, family gathering or other social event,” she said.
Confirmed Cases Statewide Stands at 770 (3 on Maui)
The total number of confirmed mumps cases statewide as of Jan. 4 stands at 770, with 610 on Oʻahu, 108 on Hawaiʻi Island, 49 on Kauaʻi and 3 on Maui.
Current Mumps Outbreak is Worst in Several Decades
The ongoing mumps outbreak is by far the worst in several decades for Hawaiʻi, which typically has fewer than 10 cases a year. Dr. Park noted that in previous years, mumps cases were imported, but recently outbreak cases have been acquired locally. What began in March 2017 as two clusters of cases involving nine individuals on Oʻahu, increased to 500, with confirmed cases in all counties, by late October 2017.
Hawaiʻi is not the only state that has experienced a mumps epidemic. According to the Centers for Disease Control and Prevention, from Jan. 1 to Dec. 2, 2017, 48 states and the District of Columbia, reported mumps infections. In addition to Hawaiʻi, Washington, Texas, Arkansas, Missouri, and New York each reported more than 300 cases in 2017.
DOH Recommends MMR Vaccine
The MMR vaccine prevents most cases of mumps and complications caused by the disease. Individuals who have been appropriately vaccinated with a routine two-dose series can still get mumps, especially if they have prolonged, close contact with someone who has the disease, but those who are vaccinated and get the mumps will likely have less severe illness than unvaccinated individuals.
“If it were not for our highly vaccinated population, we would expect to see many more cases in individuals exposed to the mumps virus, more severe illness in those who have been sick, and more complications from the disease,” Dr. Park said.
Mumps Symptoms, Complications
The most common symptoms of mumps include swollen glands in front of ears or jaw on one or both sides, fever, muscle aches, headache, loss of appetite, and tiredness. Persons with symptoms of mumps should contact their healthcare provider for testing.
Complications from mumps include orchitis (swelling of the testicles), oophoritis (swelling of the ovaries), meningitis (infection of the covering of the brain and spinal cord), encephalitis (swelling of the brain), and temporary or permanent hearing loss. In rare cases, death may also occur.
