Manitoba public health officials are warning residents about a new measles exposure at the Portage District General Hospital emergency department, on Nov. 11 from midnight to 4:30 a.m.
Anyone present during that time should monitor for symptoms until Dec. 3.
Manitoba has reported 263 measles cases in 2025, including 247 confirmed and 16 probable.
May had the highest number with 72 cases, while November has recorded just one confirmed case.
People born in 1970 or later who have never had measles or a measles vaccine are advised to get immunized. Exposed individuals should limit contact with others, especially the immunocompromised or unimmunized, from the fifth to the 21st day after exposure.
Some groups, including infants under six months, pregnant women, and those with weakened immune systems, should contact health authorities for possible preventative treatment.
Measles symptoms appear seven to 21 days after exposure and can include fever, runny nose, red eyes, drowsiness, and white spots in the mouth, followed by a red blotchy rash. Complications can include ear infections, diarrhea, pneumonia, and encephalitis.
Anyone experiencing symptoms should isolate and contact their health-care provider.
