Manitoba Health

2025 Update

The number of measles cases is rising locally, nationally and internationally. The majority of cases are unvaccinated or under-vaccinated children who have been exposed in their communities. For further information on the current measles situation in Canada refer to the following website: https://health-infobase.canada.ca/measles-rubella/

In response, Manitoba Public Health has expanded eligibility for measles containing vaccine. Effective May 14th, children aged 6 months to under 12 months residing in Southern Health-Santé Sud (SH-SS) and Interlake Eastern (IERHA), or who travel regularly to AND have close contact with residents of SH-SS or IERHA, are eligible for one dose of MMR in addition to the routine schedule offered at 12 months and 4-6 years.

Manitoba Public Health continues to monitor for measles cases and exposures that occur from cases in Manitoba, and exposures from out of province travellers to Manitoba. The information on this website will be updated to advise of these locations.

* Data is up to May 10, 2025. Website updated on May 14, 2025.

The number of cases will be updated on the website weekly each Wednesday. Public exposures will be updated as they are identified.

Note: Fluctuations in case numbers are expected as cases are investigated, and information is updated.

Individuals who were on the following flights or at the following locations may have been exposed to the measles virus:

* Exposure from an out of province case that travelled to Manitoba

Public health is asking anyone who was in these locations during these times to check their immunization records and ensure they are up to date with measles vaccine (MMR or MMRV).

• If you were born before 1970 or if you have ever received a measles vaccine, it is unlikely that you will get the disease.
• However, as a precaution, watch for symptoms of measles until the date indicated in the sites, dates and times of exposure table (the one that corresponds with your situation). To know the symptoms of measles and what to do if you have symptoms, visit here.
• If you were exposed in these locations AND born in 1970 or later AND have never received a measles vaccine, AND have never had a measles infection, you should:
• Reduce exposures with others, especially anyone who has a weakened immune system or is unimmunized, from the 5th day after exposure to the 21st day after the latest exposure. Note: Individuals are not contagious in the first 4 days following the first exposure.
• Get vaccinated. Measles vaccine is recommended.
• Watch for symptoms of measles until the date that corresponds with your situation as indicated in the table above. To know the symptoms of measles and what to do if you have symptoms, visit here.
• Close contacts may be asked by public health to isolate and consider vaccination.
• Certain people should not get the measles vaccine, including infants less than six months of age, pregnant women, and people with weakened immune systems. These individuals should contact their health care provider or public health as they may be eligible for preventative treatment.

If symptoms develop, isolate at home and contact your health care provider and advise them of your potential exposure to measles. It is best to call ahead so health-care staff can take steps to reduce the exposure of other people to the virus.
