A recent outbreak of mumps in Oklahoma impacts even patients vaccinated against the disease.

The Oklahoma State Health Department opened an investigation with county health departments in Garfield and Kay counties after the outbreak of mumps.

Health experts say the mumps vaccine found in Measles, Mumps and Rubella vaccinations may not protect against a new strain.

McCurtain County officials found cases related to ongoing outbreaks in north central Oklahoma and Arkansas.

The state health department says cases in Canadian, McClain, Osage, Tulsa and Woods counties were connected to the Kay and Garfield outbreaks.

State and local health officials are trying to identify suspected cases and keep those patients away from child care centers, schools and workplaces while they are able to transmit the infection.

Mumps symptoms usually appear between 12 and 25 days after exposure; the virus is transmittable two days before symptoms appear and up to five days after symptoms begin. The virus appears in saliva and fluid from the nose and throat.

Patients spread mumps through sneezing, coughing and direct contact with those fluids.

Despite concerns that vaccines may not stop a new strain virus, the health department recommends full vaccination to prevent the virus.

Those infected should seek medical attention and stay away from child care centers, schools and work until at least 5 days after symptoms begin. 
Symptoms typically include:
  • Swelling on one or both sides of the face
  • Tenderness of cheek and jaw
  • Slight fever
  • Headache
  • General aches and muscle pain
