Organism, Causative Agent, or Etiologic Agent

Mumps virus is a Rubulavirus in the Paramyxovirus family.

Mumps is spread by droplets of saliva or mucus from the mouth, nose, or throat of an infected person, usually when the person coughs, sneezes or talks. Items used by an infected person, such as cups or soft drink cans, can also be contaminated with the virus, which may spread to others if those items are shared.

Mumps is an illness with acute onset of parotitis—swollen or tender salivary glands (usually in the space below where the jaw and ear meet). This swelling may be on one or both sides and will usually resolve in about a week. Many people may not have any symptoms at all. Other glands can swell or become tender, most notably adult males may have swollen or tender testicles. Complications or other presentations are rare and usually mild, but include deafness, pancreatitis, oopheritis (swollen ovaries), meningitis, and encephalitis.

Cover your mouth and nose with a tissue when you cough or sneeze, and put your used tissue in the trash can. Wash hands well and often with soap and don’t share drinks or eating utensils. There is no treatment for mumps other than treating the symptoms. Anyone who is not immune from either previous mumps infection or from vaccination can get mumps. The mumps vaccine is part of the MMR (measles mumps rubella) vaccine and it is currently recommended for children to receive it at 1 and 4-6 years of age.

School Exclusion Policy
Children with suspected or confirmed mumps should be kept out of school or childcare for five days after the onset of swelling. Rules for exclusion of sick children from school and childcare are outlined in the Texas Administrative Code, specifically Rule 97.7 for schools and Rule 746.3603 for childcare.

Recent Texas Trends 

Due to high vaccination rates in Texas, mumps incidence is traditionally low, however there has been a recent surge in mumps cases. In 2016, 191 cases of mumps were reported in Texas. This had been the most number of mumps cases since 1994. There were four outbreaks in 2016 with 150 cases onset between November 1, 2016 and December 31, 2016.  Many of the cases in the outbreaks had a known 2 dose history of the mumps vaccine, which has been typical for many of the mumps outbreaks happening in the U.S. There were cases where vaccination history was unknown. The largest outbreak affected school-aged children in Johnson County and that community.
