The new B.1.1.529 variant has over 30 mutations in the part of the virus that current vaccines target and is suspected of driving a spike in new infections in South Africa. Countries from Indonesia to Saudi Arabia have imposed travel curbs for visitors from southern Africa to limit the spread. In the most far-reaching effort against the potentially more contagious variant, Israel is to ban the entry of foreigners and re-introduce counter-terrorism phone-tracking technology, it has said. Biden told it will take two weeks to have definitive data on Omicron variantThe top U.S. infectious disease official, Dr. Anthony Fauci, told President Joe Biden on Sunday it will take about two weeks to have definitive information on the new coronavirus variant Omicron that has sparked new travel restrictions and shaken financial markets. Fauci said he believes existing vaccines are likely to provide “a degree of protection against severe cases of COVID”, and officials reiterated their recommendation for vaccinated Americans to get booster shots, according to a readout of the briefing.The United States has recorded over 1.1 million new COVID-19 cases in the last 14 days, up 9% from the prior two weeks, Reuters data shows, with Michigan and Minnesota leading the nation in new cases, based on infections per 100,000 residents.

S.African doctor says patients with Omicron variant have ‘very mild’ symptomsSouth African doctor Angelique Coetzee, a private practitioner and chair of South African Medical Association who was one of the first to suspect a different coronavirus strain among patients, said on Sunday symptoms of the Omicron variant were so far mild and could be treated at home. Coetzee, who is also on the Ministerial Advisory Committee on Vaccines, said unlike the Delta variant, so far patients have not reported loss of smell or taste and there has been no major drop in oxygen levels with the new variant.Her experience so far has been that the variant is affecting people who are 40 or younger. Almost half of the patients with Omicron symptoms that she treated were not vaccinated. “The most predominant clinical complaint is severe fatigue for one or two days. With them, the headache and the body aches and pain,” she said.
