“There is some genetic material or viral material left in the individual specimens,” Dr. Vanessa Allen of Public Health Ontario said Thursday.
“We don’t know that means, whether that’s live or dead virus,” Allen said. “There’s some component of virus in those specimens and the criteria that have been laid out are being followed, that we required two negative specimens until we understand more about what that means.”
Those tests must be taken at least 24 hours apart.
