Ontario is changing its COVID-19 symptom screening guide for schools and child care centers in the province. The province is now asking parents to keep their children at home without going to school for 24 hours if they have a runny nose or headache. If a child has both symptoms, they are asked to see a healthcare provider or get tested for COVID-19 before returning to school or child care. Previously, the government had asked that children with only one symptom stay home until they received a negative COVID-19 test or other medical diagnosis. Ontario is also removing abdominal pain or conjunctivitis from its watch list. Earlier this month, British Columbia removed 10 symptoms from its school score sheet, including a runny nose.
