Mumps

Current Situation

Two mumps outbreaks, declared in the South and Edmonton Zones of Alberta Health Services (AHS) on February 16 and March 28, respectively, have been declared over.

48 cases were confirmed as linked to these two outbreaks, combined.  75 cases of mumps have been confirmed Alberta in 2017, to-date (as of June 15, 2017).

Although these outbreaks have been declared over, the risk of mumps remains worldwide, including here in Alberta.  AHS continues to urge all Albertans to ensure they, and their families, are up-to-date on all immunizations, including immunizations that protect against mumps.  

Protect yourself & your family:

Mumps is preventable through immunization.

To reduce the risk to Albertans, we need to ensure as many people as possible are up to date with their mumps immunization.

If you are unsure of how to find or check your immunization records, and/or how to make an appointment for immunization, please call Health Link at 811.

About Mumps Illness:

What is Mumps?

Mumps is a contagious viral infection that can often cause swelling and pain in the glands of the jaw (one or both cheeks may look swollen).

Some people with mumps won't have gland swelling, and some may feel like they have a bad cold or influenza instead.

How is mumps spread?

Mumps is spread when an infected person coughs or sneezes near you or shares food or drinks with you.

A person with mumps can spread the virus seven days before and for nine days after symptoms start, though it is most likely to spread one to two days before and five days after symptoms start showing.

What can happen if I have mumps?

Mumps usually goes away on its own in about 10 days, but in some cases it can cause serious complications that affect the brain (meningitis), the testicles (orchitis), the ovaries (oophoritis), or the pancreas (pancreatitis).

These complications can have life-long effects.

What should I do if I think I (or a loved one) has mumps?

Anyone with symptoms of pain on chewing or swallowing and/or swelling of the cheek or jaw should call Health Link (811) or a doctor to book an assessment and consideration of testing.

If you think that you or your child has mumps, be sure to call ahead and explain the symptoms before you go to a doctor's office. This can help reduce the risk of further spread to other patients.

Anyone with symptoms as above should stay home from school/work for 5 days from the start of swelling.
