Toronto public health officials are warning people in their teens, 20s and 30s to make sure they are properly vaccinated against measles after a recent outbreak of the illness in the city.
On Thursday, officials confirmed four new cases in the past few days. It brings the number of cases in the Greater Toronto Area to nine. There are also outbreaks in other parts of the province and in the United States.
The people affected either live or work downtown, said Dr. Barbara Yaffe, director of communicable disease control for Toronto Public Health. The agency managed to trace two points of contact — the TD Waterhouse building and the Scotia Tower, which are connected by the city's underground pathway system.
