Ontario health officials warn of possible measles exposure linked to airport and flight
Ontario health officials warned on 9 November that people who passed through Pearson International Airport, were on a particular international flight, or visited the Lakeridge Health Ajax-Pickering emergency department could have been exposed to measles. The advisory followed a confirmed measles infection in an unvaccinated child.
Durham public health officials had earlier, on 3 November, traced a confirmed measles case in an unvaccinated child who had recently traveled abroad and warned that contacts at the airport, the flight and the local emergency department might be at risk. They said they were contacting known contacts and investigating the exposure site.
