The number of confirmed measles cases in our city remains at two.
Four people last week were red-flagged by family doctors, who are being asked to keep an eye out for possible symptoms, like a rash.
All of those patients tested negative for measles.
The two cases confirmed earlier this month are students, who are unimmunized, at St. Stephen Catholic School.
Public health officials say Ottawa's vaccination rate for measles is between 82 to 95%. The reason there is such a wide range because the vaccine requires two doses, and some may not have the full immunization.
