“The school is working closely with public health officials and is following their recommendations. Close contacts have been identified and are advised to self-isolate along with their household members,” reads the letter. “If you have not been contacted by the school stating your child is a potential close contact and a public health official has not contacted you, your child has not been identified as being exposed to COVID-19 from this/these cases.” It is the second time in a week that at least one confirmed COVID-19 case was reported at McIsaac - at least one case was found in the school's blue cohort and announced May 16. The original case was believed to have been in the school May 10, 11 and 13 during a period where they may have been infectious. The blue cohort covers the Kindergarten Larouche, Grade 2 Bedford, Grade 2 Frederick and Grade 2/3 Reitlo classes. It is unknown if there is a connection between the cases in the two cohorts.
