I'll respond to that question.
Obviously, in British Columbia, the health officials and the local public health unit in charge of that particular investigation have been in very close contact with the Public Health Agency.
As I understand it, the potential transmission occurred inside a family setting. This is a household close-contact transmission setting, which is not unexpected. That does not mean that the virus was spread further. They will be doing their investigation as to exactly what the situation is.
As with any infectious disease, public health units are very equipped to do case and contact tracing and management, but it would not be unexpected to have limited person-to-person transmission in a closed-contact setting, and it does not change our risk assessment for Canada. The risk remains low.
