It is extremely unlikely for Covid-19 to spread via contaminated post, Canada’s health authorities said, after their Chinese counterparts suggested this may be the source of an Omicron case found in Beijing over the weekend.

The Beijing Centre for Disease Control and Prevention on Monday said traces of the Omicron variant had been found on a letter mailed from Toronto and received by the person, and suggested that the letter could have been the source of the infection.

On Tuesday, the Beijing CDC said a close contact of that person had also tested positive – the second local case of the highly infectious Omicron strain in the capital.

But Health Canada, in a written reply to the South China Morning Post, said while mail could be contaminated, “the risk of Covid-19 infection when handling paper mail or cardboard packages, including international mail, is extremely low”.

“In general, coronaviruses including variants do not spread from products or packaging shipped over a period of days or weeks,” the health agency said.

It came after Canadian Health Minister Jean-Yves Duclos on Monday sidestepped a question about the claim, saying he had to consult the experts, though he described it as “extraordinary”.
