Mumps

Contact the Florida Department of Health

Mumps is an infectious disease caused by a virus. Mumps starts with a fever, headache, muscle aches, tiredness, loss of appetite, and swelling of the salivary glands. It is a common illness in children and young adults. Mumps can be prevented with vaccination.

Mumps is not very common in the US any longer. From year to year, mumps cases can range from roughly a couple hundred to a couple thousand. For example in 2010, there were 2,612 cases, and in 2012, there were 229. Before the US mumps vaccination program started in 1967, about 186,000 cases were reported each year. There has been more than 99% decrease in mumps cases in the US since the pre-vaccine era.

Symptoms

  • Fever
  • Headache
  • Muscle aches
  • Tiredness
  • Loss of appetite
  • Swollen and sensitive salivary glands under the ears or jaw on either one or both sides of the face called parotitis

Complications

  • Swelling of the tissue covering the brain and spinal cord (meningitis)
  • Swelling of the ovaries called Oophoritis
  • Swelling of the testicles called Orchitis
  • Swelling of the cheeks and jaw, due to the swelling of the salivary glands
  • Deafness
  • Swelling of the brain (encephalitis)
  • Swelling of the breasts (mastitis)

Transmission

  • When an infected person coughs, laughs, sneezes, or talks the droplets of saliva or mucus from the mouth, nose, or throat can spread the virus
  • Items and objects used or touched by an infected person can be contaminated with the virus

Things to do to help prevent the spread of mumps:

  • Washing hands well with soap
  • Do not share eating or drinking utensils
  • Items touched frequently must be cleaned with soap and water or disinfecting wipes

Mumps Vaccination

The measles, mumps, rubella (MMR) vaccine is the best way to prevent mumps. The vaccine is included in the combination measles-mumps-rubella (MMR) and measles-mumps-rubella-varicella (MMRV) vaccines. Two (2) doses of MMR vaccine are recommended to prevent the disease. The first dose should be given at 12 to 15 months of age and the second dose should be given at 4 to 6 years of age.

Possible Vaccine Side Effects

  • Irritations in the arm
  • Fever
  • Swollen glands
  • Slight red rash
Mumps Surveillance Summary

December 2017

State mumps activity:

Mumps Surveillance Map
  • Six confirmed and nine probable mumps cases were reported among six counties in
    December.
  • Mumps cases have remained elevated since April with a peak of 20 cases
    reported in August.
  • From January 1, 2017 through December 31, 2017, 23 confirmed and 47
    probable cases of mumps were reported among 17 of Florida’s 67 counties.
  • In Florida, the number of reported mumps cases has remained relatively low over the past five years but started to increase in 2015 with ten cases and in 2016 with 16 cases. The last time the number of reported cases reached 2017 levels was in the 1990s.
  • Two outbreaks of mumps were reported in December. Broward County reported a mumps outbreak in a middle school and Hillsborough County reported a mumps outbreak in a university.
    • In 2017, the majority of cases have been associated with outbreaks or household clusters.
    • While mumps outbreaks can occur in highly-vaccinated communities, high vaccination coverage limits the size, duration, and spread of outbreaks.
  • In December, the highest incidence of mumps was in children age 12-18 years. This was largely driven by the previously mentioned outbreaks.
  • Vaccination is the best way to prevent mumps infections. In December, four (27%) cases had unknown vaccination history.
  • In December, ten (67%) cases visited the emergency department and one (7%) was hospitalized. In general, those who have received at least one mumps vaccination even if they later develop disease have less severe outcomes than those who have never been vaccinated.

National mumps activity:

  • Since 1989 when the two dose vaccination program was introduced, the number of mumps cases has fluctuated from a few hundred to a few thousand per year. Some years had higher numbers of cases than others mainly because of several large outbreaks in close-contact settings.
  • In 2016, there were over 6,000 cases of mumps reported, and in 2017 there have been about 5,000 cases reported. Since 2013, the 18-22
    year age group has had the highest incidence of mumps, largely driven by outbreaks. About half of the outbreaks reported since 2016 have been associated with colleges and universities, primarily affecting young adults.
