The US president Joe Biden has called Omicron Covid 19 variant a cause for concern not a cause for panic a day after it was detected in North America.
He said there is no need for the new lock down for now if people are vaccinated and wear their masks . Cases have been found in Canada and US has imposed travel bans on eight south African countries.
Mr Biden said that the pharmaceutical companies were making contingency plans for the new jabs if they are needed. At the white House on Monday the president said it was almost inevitable that Omicron first reported by south Africa would be found in US eventually.
Late last week the US announced a ban on flights from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Mozambique and Malawi
