Montreal public health warns of measles exposure at Trudeau airport and the Sainte-Justine hospital
Montreal public health said a person with contagious measles had been at Montréal-Trudeau International Airport, and that people may have been exposed at the Sainte-Justine pediatric hospital, according to the Montreal Gazette, CBC, CTV News, CityNews Montreal, Global News and Radio-Canada. La Presse, TVA Nouvelles, the Journal de Montréal and Le Devoir described a new case in the city. The headlines we read do not give dates, times or flights. We saw no report of a second case linked to this one.
Measles is among the most contagious infections known, and airports and children's hospitals concentrate travellers and people who are especially vulnerable, such as infants too young to be vaccinated.
If you were at the airport or at Sainte-Justine in the period named in the public-health notice, read the notice, check your vaccination record and watch for fever or a rash. Call ahead before visiting a clinic.
Prompt, place-specific warnings are how a single case is kept from becoming a cluster.
Warnings that name busy places can alarm many people who were never at risk; the dates and times in the notice are what matter.
The thing to read is the notice itself, not the headline. If you are fully vaccinated, your risk is low. If you are not sure, ask your clinic. Watch for any further exposure notices in the coming days, since symptoms can take up to about three weeks to appear.
