OKLAHOMA CITY – Health officials across Oklahoma are still investigating an outbreak of mumps that has affected several counties across the state.

Authorities with the Oklahoma State Department of Health say cases in Canadian, McClain, Osage, Tulsa and Woods counties are all connected to an outbreak in Garfield in Kay counties.

So far, 324 people across Oklahoma have been diagnosed with the mumps related to the outbreak.

Garfield County saw the brunt of the outbreak with 279 cases occurring there, while 19 cases were reported in Kay County.

Officials say only one of the patients had to be hospitalized, but there is another part of the outbreak summary that is concerning health experts.

Investigators learned that 214 of those who were diagnosed with the mumps had received the MMR vaccine. In all, 109 of the patients had not received the vaccine, and one child was too young to receive the vaccine before he or she was diagnosed.

Right now, health experts are investigating 33 other possible cases.

Mumps is a virus that is spread by coughing, sneezing and direct contact with saliva, like eating or drinking after an infected person.

Symptoms include swelling on one or both sides of the face, tenderness of the salivary glands in the cheek and jaw area, slight fever, headache, general aches and muscle pain.

Those symptoms usually appear 16 to 18 days after the infection, and individuals can begin spreading the virus two days before showing symptoms.

Experts say patients will usually recover on their own, but some cases can lead to serious complications.
