The 20-year-old man lives in Winnipeg and was in direct contact with the first case of measles identified in Manitoba earlier this month.
Public Health officials are working on the case with the Winnipeg Regional Health Authority to identify further contacts at the University of Manitoba on March 20 and at Concordia Hospital’s emergency department on March 22.
In the first case, a man in his 40s who teaches and coaches sports teams at a school in Lockport, Man., came down with the illness.
He had attended a badminton tournament in Winkler, Man., on March 7 and 8; a volleyball tournament in Winnipeg on March 8 and 9; and visited the Victoria Hospital emergency department in Winnipeg on March 9 and the Selkirk hospital's ER the next day.
Health officials are advising people to get vaccinated, something that's free for children under 12 months of age and for adults born after or during 1970 who have not had a measles-containing vaccine.
