A man in Saxony has been infected with the Omicron variant of the coronavirus without having been in South Africa before. A spokeswoman for the city of Leipzig confirmed corresponding media reports to SPIEGEL.

"I have just received confirmation of an Omicron detection in the mutation analysis for a 39-year-old patient," the "Bild" newspaper quoted Regine Krause-Döring, head of Leipzig's public health department, as saying. According to the "Leipziger Volkszeitung," she expressed concern at an online meeting with Saxony's Prime Minister Michael Kretschmer (CDU) about the fact that, according to her, the man had neither been abroad nor had any contact with people returning from abroad.

The new coronavirus variant, Omicron, has been detected in two Israeli doctors, one of whom had returned from a conference in London in the past week, a spokesperson for Sheba Medical Center near Tel Aviv confirmed on Tuesday.

The two doctors had received three doses of the Pfizer/BioNtech vaccine, and so far have shown mild COVID-19 symptoms, the hospital said.

The physician who had returned from Britain had probably infected his colleague, it said.

All nine cases of the Covid Omicron variant that have been reported in Scotland have been linked to a single “private event” which took place on 20 November.

None of the nine people had recently travelled to southern Africa where the variant was originally detected, or were in contact with anyone who had.

iako zvuci paradoksalno, dugorocno bolje je imati letalniji soj, on bi se za kratko vreme samoubio uz dobro izolovanje slučajeva, kao što se desilo sa MERS-om

[Roger Sanchez]

Mislim da u nadama nismo mislili na manje smrtonosan soj, pogotovo ne samo 50% manje smrtonosan, nego na soj koji gotovo da nije smrtonosan uopće, jer se ne baca više na pluća.

The unvaccinated fill SA hospitals amid emergence of Covid-19 Omicron variant

Johannesburg - The government has continued to urge South Africans to vaccinate against Covid-19 as recent statistics revealed that more than 80% of patients currently admitted to hospitals in Pretoria were unvaccinated.

The National Institute for Communicable Diseases (NICD) reported that Covid-19 cases, including that of the new Omicron variant, were highest in Gauteng, and in particular Pretoria.

"Most of our daily increases at this stage are from Gauteng, at about 81%. There has been a tremendous increase in the past 10 to 14 days,” said Dr Michelle Groome, head of the division of public health surveillance and response at the NICD.

Dr Waasila Jassat, also of the NICD, said that unvaccinated patients suffered more severe symptoms than vaccinated ones, and were most likely to face hospitalisation if infected by the new Covid-19 variant. She reported that 87% of all admissions in Pretoria were unvaccinated patients.

“We have been tracking this across the country since February, and what we can say is there is a much higher chance of death among those who are unvaccinated,” Dr Jassat said.

She was one of many experts who provided detailed feedback during a media briefing held by the Health Ministry yesterday.

Dr Salim Abdool-Karim, who also presented, said they were quite amazed at how fast the number of infections was rising, “but we were not caught with our pants down”.

“We expected and prepared for a new variant as far back as in September. The government then invested in building capacity to do genomic frequency, and this early evidence has given us the best fighting chance against this new variant,” he said.

Abdool-Karim said that while there was still a lack of evidence on whether the current vaccines were effective against the new variant, he said that evidence should present itself over the next few weeks.

“But, we do expect that vaccines should hold well against the hospitalisation of those who are infected,” he said.

He added that the biggest challenge would be preventing super-spreader events.

The scientists and department also urged those who were already vaccinated to motivate others to vaccinate and strictly follow preventive measures such as mask-wearing and the washing of hands.

Minister of Health Joe Phaahla said the rise of infections served as a reminder there was a deadly virus in our midst, and that citizens should use what was tried and tested in preventing severe cases of Covid-19.

While more than 16.5 million South Africans are fully vaccinated, the department’s Dr Nicholas Crisp said that many more people remained unvaccinated.

So far, early information showed that most Covid-19 patients admitted to hospital and experiencing severe symptoms were unvaccinated, the department said.

Phaahla held a detailed media briefing on Monday to further unpack the address by President Cyril Ramaphosa, and to present a state of readiness to respond to the Omicron variant.

Research has also shown that most patients are presenting similar symptoms to other Covid-19 variants. However, in particular, concerns have been raised about the rise of infections in young children and babies.

Scientists and experts that presented at the briefing said the Health Department may have to focus on paediatric hospital beds preparedness in this fourth wave.

Dr Jassat said they had seen a sharp increase in infections over the past few days, with most cases among those aged between 10 and 29 years old.

She also spoke of the increase in the number of hospital admissions in Pretoria, however other regions in Gauteng also showed an increase.

The experts also spoke out against the closing of South Africa’s borders, saying that there was no science to support such decisions.

Phaahla, Abdool-Karim and Department of International Relations and Co-operation (Dirco) spokesperson Clayson Monyela reiterated the government’s frustration at the decision made by other countries.

Abdool-Karim said there was no benefit in closing the borders as the Omicron variant had been detected in at least 11 other countries by yesterday.

Monyela said that they had received reports from South Africans stranded in cities around the world. He said any stranded South African must go to their nearest South African embassy for assistance.

“It is very unfortunate, sad and quite regrettable to know that travel restrictions have been imposed on South Africa by other African countries. This decision is unwarranted and not based on science. Dirco is engaging all the countries with a view to persuading them to reverse this decision,” he said.

Belgija, nema veze s omikronom:

 

Quote

In the last two weeks, about 20 unvaccinated Corona patients over age 65 per 100,000 population ended up in the ICU, but only 5 vaccinated. In the 18 to 64 year old group, 9 unvaccinated Corona patients per 100,000 population landed in the ICU in the past two weeks. In contrast, only one vaccinated Corona patient per 100,000 population received intensive care. 

"The fully vaccinated ICU patients tend to be somewhat older," says Steven Van Gucht. "Mainly people over 70 with underlying diseases, while the non-vaccinated patients in the hospital are on average twenty years younger."

Odličan intervju južnoafričkog epidemiologa Tulija de Oliveire za Njujorker:

Evo detaljnog opisa kako je otkriven omikron:

Quote

When did you first have a sense of the existence of this new variant?

 

I am the principal investigator and leader of the Network for Genomic Surveillance in South Africa, which involves seven genomic facilities distributed across the country. There was an uptick of cases in Gauteng Province. It was only a small uptick—we had around two hundred cases in the whole country every day. But they started growing, and so we met with our network and said we needed to understand why they were growing in the province that had the largest previous wave of infections of Delta. That variant was extreme in Gauteng, with somewhere between sixty and eighty per cent of people having gotten infected by covid, according to serology testing.

So on Friday, November 19th, we decided that we needed to increase genomic surveillance in Gauteng. And by last Tuesday we heard from one member in our network that a private lab, Lancet Laboratories, had sent in six genomes of a very mutated virus. And, when we looked at the genomes, we got quite worried because they discovered a failure of one of the probes in the P.C.R. testing. We went back to all the national data and noticed this failure was increasing in a lot of the P.C.R. tests. The P.C.R. tests still worked because they had three probes, but one of them was a failure. And then we discussed the six genomes. We were surprised, but we had to make sure it wasn’t just a small chain of transmission. It was widespread. So we had that meeting last Tuesday, and I asked for samples from other labs.

When I noticed that mutated variant on Tuesday, I phoned the director general of health, and he told me he would set up a meeting with me and the minister of health in thirty-six hours. So we had thirty-six hours to confirm whether it was real. At the same time I wrote to the World Health Organization, because I am a part of the virus-evolution working group. The next morning, we got over a hundred samples from over thirty clinics in Gauteng, and we started genotyping, and we analyzed the mutation of the virus. We linked all the data with the P.C.R. dropout, the increase of cases in South Africa and of the positivity rate, and then we began to see it might be a very suddenly emerging variant. By Thursday morning we got all the genomes back, and they were all the same variant—around a hundred randomly selected samples, from all over Gauteng, in which the same test failed. By then I was confident enough to present the results to our minister of health, and minister of science and innovation, who took the results quite seriously and asked me to talk to the President, Cyril Ramaphosa, at half past 10 a.m., which I did.

 

What was that conversation like?

 

He looked at the results and got the comments from the ministers, and by that time the first reports were coming in the media of a potential new variant from Southern Africa. So the President gave a simple answer: it is better that we present it in a transparent format, because we have enough evidence. And then he asked the minister of health to organize a press briefing at midday. So the time from when we discovered the variant and then confirmed its existence in hundreds of samples across the province to when we presented it to key ministers and talked to the President and went public with it was around thirty-six hours.

Nedeljni rast hospitalizacija u najpogođenijoj južnoafričkoj provinciji Gauteng (trenutno 136%) daleko je veći nego u prethodna dva talasa - u zimskom bio je najviše 69%, a u letnjem 43%.

Da sačekamo još malo, ali ne izgleda dobro. Ostaje još da se vidi infektivnost i težina bolesti kod vakcinisanih i ranije inficiranih.
