How is mumps caused




















This is what causes the puffy cheeks and a tender, swollen jaw. Guidance for optimizing mumps testing practices, when to use a 3rd dose of MMR vaccine during outbreaks, job-aid for providers. Fact sheets, MMWR articles, pink book chapter on mumps, surveillance manual chapter on mumps, video and other digital materials about mumps vaccination and outbreaks. Even though the vaccine has drastically reduced mumps cases, outbreaks still occur. Outbreaks have most commonly occurred among groups of people who have prolonged, close contact, such as sharing water bottles or cups, kissing, practicing sports together, or living in close quarters, with a person who has mumps.

Some vaccinated people may still get mumps if they are exposed to the virus. Related Links. Links with this icon indicate that you are leaving the CDC website.

During mumps outbreaks in highly vaccinated communities, the proportion of cases that occur among people who have been vaccinated may be high.

This does not mean that the vaccine is ineffective. The effectiveness of the vaccine is assessed by comparing the attack rate in people who are vaccinated with the attack rate in those who have not been vaccinated.

In outbreaks of highly vaccinated populations, people who have not been vaccinated against mumps usually have a much greater mumps attack rate than those who have been fully vaccinated. Disease symptoms are generally milder and complications are less frequent in vaccinated people. Vaccination is the best way to prevent mumps and mumps complications.

In October , the Advisory Committee on Immunization Practices ACIP recommended that people identified by public health authorities as being part of a group at increased risk for acquiring mumps because of a mumps outbreak should receive a third dose of MMR vaccine. The purpose of the recommendation is to improve protection of people in outbreak settings against mumps disease and mumps-related complications. See Mumps Vaccination for vaccination recommendations.

RT-PCR and viral culture are used to confirm mumps infection. IgM serology can also be used to aid in diagnosing mumps infection. A negative test result does not rule out mumps infection. Mumps is a nationally notifiable disease, and all cases should be reported to the state or local health department. Contact your state health department for more information on how to report mumps in your state. Mumps transmission in healthcare settings, while not common, has occurred in past outbreaks, involving hospitals and long-term care facilities housing adolescents and adults.

Information about what measures to take to prevent and control mumps in healthcare settings can be found under the Healthcare Setting section of the Manual for the Surveillance of Vaccine-Preventable Diseases , Chapter 9: Mumps.
