Manitoba's medical officer of health says the province's eighth confirmed case is a man in his 30s who lives in the Winnipeg area.
Officials say anyone who was at Teasers Burlesque Palace on April 25 from 10 p.m. to midnight may have been exposed to the man has the disease.
They are urging anyone who may have visited this location and think they have measles to call their doctor.
Symptoms of measles generally appear seven to 21 days after exposure and can include fever, runny nose, drowsiness, irritability and red eyes.
Several days after the initial symptoms, a red blotchy rash appears on the face and progresses down the body —measles can lead to complications including ear infections, diarrhea, pneumonia and encephalitis.
An infected person can spread the virus from four days before the rash appears to four days after it is seen. The disease tends to be more severe in infants and young children, and can be life-threatening.
Adults born before 1970 are generally presumed to have acquired natural immunity to measles, however, some of these individuals may be susceptible.
Adults born in 1970 or later who do not have a record showing they received a measles vaccine, or who have not had a history of laboratory confirmed measles infection, should be immunized with one dose.
