LONDON, ONT. As asymptomatic testing begins in London-area public schools this week, many parents fear a resurgence of the virus. Claudia Baldizon tells CTV News her children are impacted by school outbreaks. “It’s hard to hear, that not one, but two of my kids were close contacts, the same week. And obviously, with cases rising, especially in this area, it’s scary.” Baldizon lives in south London. One of her impacted children attends Sir Arthur Carty Catholic Elementary School. There, four cases of the virus are reported. Both of her kids are self-isolating at home and are currently not showing symptoms.
