Since September 1, 2016 and up to November 15, 2017 there have been:

  • 1,268 confirmed cases of Mumps reported to Manitoba Health, Seniors and Active Living.
  • Cases of mumps continue to be reported in Manitoba.  While initially the majority of cases were University students between 18 to 29 years of age, living in Winnipeg, or involved with or participate in sports, mumps cases are now being seen in all ages and throughout Manitoba. See below for public and Health Care Provider resources.
  • Cases are confirmed through Public Health investigation. Public health investigation also determines if the cases are linked to the ongoing outbreak with the University of Manitoba students and identifies any places they have visited and potential people they may have been in contact with during the period when they were contagious.
  • Updates will be posted each Friday, until evidence shows that there are no additional cases associated with this outbreak.

People who think they might have mumps, or have been in close contact with someone who has been diagnosed with mumps, should phone their health-care provider or phone Health Links-Info Sante at 204-788-8200 or 1-888-315-9257 (toll-free) for more information.

Symptoms

Symptoms generally occur between 12 to 25 days after infection and resolve three to ten days after onset of illness. The most common are fever and swollen cheeks and neck. Swollen cheeks and neck are due to swollen glands, usually under the ears or jaw on one or both sides of the face.

Approximately 20 per cent of those infected with mumps will not show any symptoms. Nearly half of those infected have mainly respiratory symptoms.

Causes

Mumps is caused by the mumps virus, which is spread through respiratory droplets in the air formed when coughing or sneezing and through the sharing of food or drinks. You can also catch it by touching an item that was previously touched by an infected person and then touching your eyes or mouth.

Treatment

There is currently no cure for mumps. Current treatment focuses on relieving the symptoms.

Prevention

Mumps can be prevented through immunization. Manitoba has a provincial immunization program, which provides free, publicly-funded vaccines to those who are eligible.

The average incubation period for mumps, which is the time from exposure to when the appearance of symptoms occurs, is 16-18 days with a range of 12-25 days.

A person is infectious from seven days before to 5 days after the onset of swollen glands. Maximum infectiousness occurs 2 days before symptoms until 5 days after. A person with no symptoms can transmit infection.

Other precautions can be taken, including practicing good hand hygiene, covering your mouth with a tissue or your shirt sleeve when you cough or sneeze, and avoiding sharing of personal items.

Most people who have mumps will be protected (immune) from getting mumps again.  There is a small percent of people though, who could get re-infected with mumps and have a milder illness.
