SYDNEY: Australia on Monday halted a plan to relax border restrictions imposed last year to fight the Covid pandemic, as a new variant sweeping the world prompted the WHO to warn of potential "severe" consequences.
Countries across the world have reacted to the Omicron strain, first identified in southern Africa, by slamming their borders shut despite the variant having already reached Europe, Asia and North America.
Australia, which has already confirmed five cases of Omicron, was set to relax restrictions on skilled workers and students from Wednesday in a boon to industries suffering labour shortages under one of the world's toughest border regimes.
But Prime Minister Scott Morrison announced a two-week delay on the plan to allow Australia to gather information on the new variant, following announcements from Japan and Israel of bans on foreign travellers.
The World Health Organization (WHO) said the overall risk from Omicron was "very high" and warned that any major surge would put pressure on health systems and cause more deaths.
The first confirmed case of the Omicron variant was in South Africa on November 9, with infections spreading rapidly in the country -- although no deaths have yet been reported, according to the WHO.
It warned however that "if another major surge of Covid-19 takes place driven by Omicron, consequences may be severe."
Scientists in South Africa flagged the new strain last Thursday, prompting several European countries to quickly ban flights from the region.
That irritated South African officials who said they were being "punished" for identifying a strain that has now been detected everywhere from the Netherlands to the UK, Canada to Hong Kong.
The WHO's Africa branch said barring travellers from the continent "attacks global solidarity", and Malawi's President Lazarus Chakwera accused Western countries of "Afrophobia". Underlining the difficulties of containing the spread, Austria and Scotland, which both have flight bans in place from several African countries, confirmed their first cases of Omicron on Monday.
Nevertheless, Japan joined a growing list of countries reimposing tough border controls, barring all new foreign arrivals. The Philippines also said it would temporarily suspend plans to allow in fully vaccinated tourists.
It remains unclear how infectious Omicron is and how resistant it could be to vaccines.
The WHO's latest technical update called it a "highly divergent variant with a high number of mutations", warning that some of these mutations might be associated with easier transmission and may have the potential to dodge protections including vaccination -- though this is yet to be demonstrated.
South African doctor Angelique Coetzee, who raised the alarm over Omicron, said it was a shame that it had been labelled "extremely dangerous" as the cases she had seen suggested the symptoms were milder than other variants.
Portugal on Monday became the latest country to confirm a potential outbreak of the new variant -- at a top-flight football club that was forced to field nine players in a match that was eventually called off with the team 7-0 down. - AFP
