GENEVA: The World Health Organization (WHO) urged countries to boost healthcare capacity and vaccinate their people to fight a surge in Covid-19 cases driven by the Omicron variant, saying that travel curbs could buy time but alone were not the answer.
Despite shutting its borders to travel from high-risk southern African countries, Australia became the latest country to report community transmission of the new variant, a day after it was found in five US states.
Omicron has gained a foothold in Asia, Africa, the Americas, the Middle East and Europe and has reached seven of the nine provinces of South Africa, where it was first identified.
Many governments have tightened travel rules to keep the variant out.
"Border controls can buy time but every country and every community must prepare for new surges in cases," Takeshi Kasai, the WHO's western Pacific director, told a media briefing.
"People should not only rely on border measures. What is most important is to prepare for these variants with potential high transmissibility. So far the information available suggests we don't have to change our approach." Kasai urged countries to fully vaccinate vulnerable groups and stick to preventive measures such as mask wearing and social distancing.
Omicron has been listed as a "variant of concern" by the WHO and scientists are still gathering data to establish how severe and contagious it is just as parts of Europe have been hit by surges of winter infections by the more familiar Delta variant.
"I have not seen reports of Omicron-related deaths yet," WHO spokesman Christian Lindmeier told a UN briefing in Geneva.
But vaccine makers should prepare for the likelihood of adjusting their products to protect against Omicron, he said.
Ugur Sahin, CEO of Germany's BioNTech, which makes a Covid vaccine with Pfize, said the company should be able to adapt the shots relatively quickly.
Sahin also said that current vaccines should continue to provide protection against severe disease, despite mutations.
Australia's chief medical officer, Paul Kelly, said Omicron was likely to become the dominant variant globally within months, but at this stage there was no evidence it was any more dangerous than Delta.
Global travel curbs have accelerated with Hong Kong, the Netherlands, Norway and Russia, among others, announcing new measures on Thursday.
Aside from wreaking havoc in the travel industry, the clampdown has pounded financial markets and undermined major economies just as they were beginning to recover from the lockdowns triggered by Delta.
Bank of England policymaker Michael Saunders, who voted for an interest rate hike last month, said on Friday he wanted more information about Omicron before deciding how to vote this month. — Reuters
