In the advisory issued on January 24, the WHO advised countries to implement temperature screening at first ports of entry and focus on early screening at first ports of entry. They said, “The risk of importation of the disease may be reduced if temperature screening” is implemented at the first port of entry and is “associated with early detection of symptomatic passengers and their referral for medical follow up.”
Why is it, then, that Canada refused to actually implement temperature screening at this point and waited months to implement that emergency measure?
