Two new measles exposure sites have been identified by the province, including in Lorette.
Friday afternoon, the Manitoba Health sent out notification that those at Collège Lorette Collegiate on May 12 between 8:20 a.m. to 1:30 p.m. may have been exposed to the disease.
Those at Prairie Dale School in Schanzenfeld on May 12 between 9 a.m. and 5:30 p.m. may also have been exposed.
"Public health is communicating directly with the school to notify staff, volunteers and families of students who attend the school and/or who ride the school bus to provide advice specific to their exposure," the province says.
"All families of students, and school staff and volunteers will be receiving letters with the relevant information."
Public health asks people who think they may have been exposed to measles at these places, but who haven't been contacted, to call Health Links-Info Santé at 204-788-8200 in Winnipeg, or 1-888-315-9257 toll-free in Manitoba.
Measles symptoms
"Measles is a highly infectious communicable disease that is spread through droplets in the air formed when coughing or sneezing," the province says.
It notes measles symptoms usually appear one to three weeks after exposure.
Symptoms at the beginning could include a runny nose, drowsiness, irritability and red eyes, it says. Small white spots could also grow in one's moth or throat.
Later, the province says symptoms could progress to a red, blotchy rash on the face and progress down the body.
The disease can lead to ear infections, diarrhea, pneumonia, and brain inflammation, it says.
Measles is usually more severe in infants and young children, Manitoba Health says, and can be life-threatening.
What to do if symptoms develop, and prevention
Should someone develop measles symptoms, the province says they should isolate at home and contact their health-care provider.
"Immunization is the only means of protecting people from contracting measles. Contact an immunization provider such as a local public health office, physician or nurse practitioner to ensure everyone is up to date," it says.
Public health officials continue to monitor the situation and will provide updated information as necessary.
There are a total of 60 measles cases in Manitoba, and 4 probable cases.
