TORONTO (REUTERS) - Canada's ban on travellers from southern African countries and its refusal to recognise these countries' polymerase chain reaction (PCR) tests, aimed at preventing the spread of the Omicron coronavirus variant, are an obstacle for Canadians heading home and increasing international pressure to reverse the measures.
Canada, the United States, Britain and other countries have enacted Africa-specific travel bans even as Omicron is detected in more than 50 countries around the world.
Few countries have imposed Omicron restrictions similar to Canada's requirement that travellers from 10 southern African countries get PCR tests in a third country before coming to Canada.
In the face of travel snarls and accusations that these measures are punitive and lack evidence, Canada is under pressure to reverse them.
The head of the World Health Organisation, Dr Tedros Adhanom Ghebreyesus, called actions barring southern African countries "disappointing" and "dismaying" in a tweet on Sunday (Dec 5).
Two United Nations agencies pleaded on Tuesday for bans to be imposed only as a last resort in response to new variants.
Dr Anthony Fauci, the top US infectious disease official, said he hoped the United States would lift its ban on travellers from southern African countries in a "reasonable period of time".
Canada's ban caught travellers, including the junior women's field hockey team, off guard. Some complained of mixed messaging from government agencies.
Dr Richard Saunders, a Canadian politics professor who had been doing fieldwork in Zimbabwe and South Africa, was desperate to return home last week.
The Canadian High Commission suggested that he fly to Addis Ababa and get a Covid-19 test there despite Canada's advising its citizens not to travel to Ethiopia because of the armed conflict.
When Canada eventually made a limited-time exemption for certain Lufthansa Airways flights through Frankfurt, Dr Saunders almost missed the news as the message from the Canadian authorities slipped into his junk folder.
"I've been working in southern Africa for 40 years and the damage this does to Canada's reputation as a fair player, a fair dealer, is really significant," Dr Saunders said as he awaited the outcome of his latest Covid-19 test from hotel quarantine near Toronto's airport.
It remained unclear on Tuesday what would happen to Canadians trying to leave South Africa after Dec 13, the date Canada's Lufthansa exemption ends.
A spokesman for Global Affairs Canada said Canadians should e-mail the government department. There are more than 1,800 Canadians registered with Global Affairs in South Africa but registration is voluntary. It is unclear how many want to leave the country.
Global Affairs did not immediately comment when asked about how the measures impact Canada's reputation.
"The health rationale is a rationale that has been assessed and proposed by the Public Health Agency of Canada, the experts," Health Minister Jean-Yves Duclos told reporters on Tuesday. He would not explain the reasoning.
The agency did not respond on Tuesday or Wednesday when asked to provide the country-specific Covid-19 travel advice it gave the government.
Global health experts criticised Canada for amassing vaccines when poorer countries lacked them, said Dr Prabhat Jha, an epidemiologist and public health specialist at the Centre for Global Health Research at St Michael's Hospital in Toronto.
"This has made it worse," he said, adding that he has South African colleagues now questioning whether they should collaborate and share data with Canada. "It's theatre and not science... It's damaging in the medium and long term."
