Public health officials are reporting a second lab-confirmed case of measles in Manitoba.
The person contracting the illness was a Winnipeg man in his 20s.
The Health Department said he had been in direct contact with the first known measles case -- a man in his 40s living in the area served by the Interlake-Eastern Regional Health Authority. The first case was reported more than a week ago.
Provincial public health officials are working with the Winnipeg Regional Health Authority to investigate the case and identify contacts.
They say people who were at the following locations and events should be aware of the possibility of infection:
University of Manitoba, March 20, at the following locations and times:
- St. Paul's College, Room 225 from 11:30 a.m. to 1 p.m.;
- Machray Hall, Room 418 from 1 p.m. to 2:30 p.m.;
- EITC-E2, Room 105 from 4 p.m. to 5:30 p.m.;
- Frank Kennedy study hall, from 2:30 to 4 p.m. and from 5:15 p.m. to 8 p.m.; and
Concordia Hospital emergency department, March 22 between 10:15 p.m. and 10:40 p.m.
Those who visited these locations and who think they might have measles or have been in close contact with someone who has been diagnosed with measles should phone their health-care provider or Health Links-Info Santé at 788-8200 or 1-888-315-9257 (toll-free) for more information.
Where appropriate, people will be offered immunization and may be asked to remain at home and minimize contact with others to reduce the possible spread of measles. Public health officials will continue to monitor the situation in Manitoba and provide updated information as necessary, the government said in a press release.
"If visiting a physician or health-care provider, it is best to call ahead and make an appointment so health-care staff can take steps to reduce the exposure of other people to the virus," the government said.
In Manitoba, a measles immunization program was established in 1967. In 1996, the current two-dose measles/mumps/rubella (MMR) vaccine program was introduced.
Vaccines are provided for children who are at least one year of age and a second dose is given when aged four to six. The effectiveness of a single dose of measles vaccine given at 12 or 15 months of age is estimated to be 85 to 95 per cent. With a second dose, efficacy is almost 100 per cent.
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 a history of laboratory confirmed measles infection, should be immunized with one dose of MMR.
In Canada, measles activity is currently being reported by British Columbia, Alberta, Saskatchewan and Ontario, mostly related to ongoing outbreaks in the Philippines and the Netherlands.
