Fears new Covid super-variant Omicron ALREADY is already in Australia

  Fears new Covid super-variant Omicron ALREADY is already in Australia Health Minister Greg Hunt on Saturday announced Australia would be joining Europe and the US in closing its borders to nine southern African countries to stop the new variant from entering the country. There are though 20 returned travellers quarantining in the Northern Territory who were repatriated from South Africa last week - one of whom has tested positive to Covid.Health officials in the Northern Territory are expected to confirm whether or not the infected case has the hyper-virulent new variant later on Saturday evening.

The World Health Organization’s (WHO) chief scientist has urged people not to panic over the emergence of the Omicron coronavirus variant and said it was too early to say if vaccines would need to be reworked.

Speaking in an interview at the Reuters Next conference on Friday, Soumya Swaminathan said it was impossible to predict if Omicron would become the dominant strain.

Omicron has been detected in at least 38 countries 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.

Swaminathan said Omicron appeared to be “highly transmissible” and cited data from South Africa showing the number of cases doubling daily.

“How worried should we be? We need to be prepared and cautious, not panic, because we’re in a different situation to a year ago,” she said.

“Delta accounts for 99 percent of infections around the world. This variant would have to be more transmissible to outcompete and become dominant worldwide. It is possible, but it’s not possible to predict.”

Much remains unknown about Omicron, as parts of Europe grapple with a wave of infections of the more familiar Delta variant.

“We need to wait, let’s hope it’s milder … but it’s too early to conclude about the variant as a whole,” Swaminathan said.

The WHO said on Friday it had still not seen any reports of deaths related to Omicron.

What you need to know about the omicron variant

  What you need to know about the omicron variant Omicron is the newest Covid-19 “variant of concern,” according to the World Health Organization.Though the variant’s existence was first reported by South Africa, it has also been found in Belgium, Botswana, Germany, Hong Kong, Israel, Italy, and the United Kingdom, meaning the variant has already spread — though how far is unclear, as new cases continue cropping up around the world.

The WHO’s emergencies director, Mike Ryan, said on Friday there was no evidence to support a change in vaccines to tailor them to Omicron.

“Right now, we have highly effective vaccines that are working. We need to focus on getting them more equitably distributed. We need to focus on getting people most at risk vaccinated,” Ryan said at a social media event.

WHO spokesman Christian Lindmeier told a United Nations briefing in Geneva that vaccine makers should prepare for the likelihood of adjusting their products.

Ugur Sahin, CEO of Germany’s BioNTech, which makes a COVID vaccine with Pfizer, told the Reuters Next conference the company should be able to adapt the shots relatively quickly.

Sahin also said current vaccines should continue to provide protection against severe disease, despite mutations.

“I believe in principle at a certain [point in time] we will need a new vaccine against this new variant. The question is how urgent it needs to be available,” Sahin said.

COVID around the world: Israel to ban foreigners as other nations tighten restrictions on Britons

  COVID around the world: Israel to ban foreigners as other nations tighten restrictions on Britons Global concern about the coronavirus pandemic is growing, with a number of countries detecting confirmed cases of the Omicron variant for the first time. © Associated Press Travel restrictions are being imposed once again as governments suspend flights from southern Africa Travel restrictions are also being imposed once again as governments suspend flights from southern Africa, the region where this strain was first detected. Here is a look at the latest COVID-19 developments around the world.On Saturday, Israel unveiled plans to ban all foreigners from entering the country.

Omicron was first reported to the WHO from South Africa on November 24, while the first known laboratory-confirmed case was identified from a specimen collected on November 9.

Maria Van Kerkhove, the WHO’s technical lead on COVID-19 said a backlog of virus sequences had built up in November, meaning some of the earliest cases may yet be found outside South Africa.

The number of COVID-19 infections topped three million in South Africa on Friday as new daily infections driven by the Omicron variant rose steeply, official figures showed.

On Friday 16,055 new cases were reported in a 24-hour reporting cycle, taking the cumulative laboratory-confirmed cases to 3,004,203.

“This increase represents a 24.3 percent positivity rate,” the government-run National Institute for Communicable Diseases said in a daily update.

Worrying vaccination gaps

Vaccination rates vary from country to country, but there are worrying gaps in poorer countries. Indonesia, the world’s fourth most populous country and once Asia’s COVID-19 epicentre, has fully inoculated only about 35 percent of its population.

Sajid Javid says Christmas will be 'great' despite Omicron strain

  Sajid Javid says Christmas will be 'great' despite Omicron strain Sajid Javid said the government was taking 'proportionate and balanced' precautions to 'buy time', but stressed there is no certainty that the 'super-mutant' strain will be able to dodge jabs.The Health Secretary said the government was taking 'proportionate and balanced' precautions to 'buy time', confirming that masks will be compulsory again in shops and on public transport from Tuesday.

The head of the Red Cross said on Friday the emergence of Omicron is the “ultimate evidence” of the danger of unequal vaccination rates around the world.

“The scientific community has warned the international community on several occasions about the risks of very new variants in places where there is a very low rate of vaccinations,” Francesco Rocca, the president of the International Federation of Red Cross and Red Crescent Societies, told the AFP news agency in an interview in Moscow.

About 65 percent of people in high-income countries have had at least one dose of vaccine against the coronavirus, compared with just more than 7 percent in low-income countries, UN numbers show.

Many scientists say the way to stop the virus from spreading is to make sure poorer countries have access to vaccines, not to give blanket booster shots to people in richer countries.

Almost 264 million people have been reported to be infected by the coronavirus since it was first detected in central China in late 2019 and 5.48 million people have died, according to a Reuters tally.

Omicron 3 times more likely to cause reinfection than previous COVID variants: researchers .
South African scientists say the risk of reinfection from the omicron COVID-19 variant is at least three times higher than for any previous variant. In the preliminary study, researchers looked at approximately 2.8 million positive coronavirus infections between March 2020 and Nov. 27, 2021, and 35,670 suspected reinfections were identified. From this retrospective analysis, the group said increases in primary infection were observed following the introduction of both the beta and delta variants, but no corresponding increase was observed in the reinfection hazard.
