Coronavirus Covid-19 - opšta tema

The Omikron variant of the coronavirus puts authorities and governments worldwide on alert. Also in Switzerland. On Tuesday, the first two confirmed cases in Switzerland became known. A third followed on Wednesday.

As the Basel-Stadt health department announced on Tuesday evening, one of the cases that became known on Tuesday concerns the canton of Basel-Stadt. Now it is clear: The case occurred at the high school Kirschgarten.

Mild symptoms

The background is largely unclear. As the health department of Basel City writes in a media release on Wednesday, the affected is a 19-year-old grammar school student. "The source of infection is unknown, there was no travel activity in advance." The case was discovered with the regular mass testing in schools. The subsequent single test was sequenced and the Omikron virus was confirmed, he said.

The student was fully vaccinated and placed in isolation, according to the release. He has only mild symptoms. During the contagious period, he had contact with his class and with the choir and orchestra, with whom he had a performance last week. The contact tracing team has informed school administration, parents and other private contacts of the student. About 100 people will have to be quarantined for ten days.

Spectators not in quarantine
As Blick knows, the affected person performed on November 23, 2021 in the St. Martin's Church in Basel. The annual concert of his orchestra took place there. The church was packed with spectators. Because certificates were required at the event, there was no mask requirement. The people who had to be quarantined were from the choir, the orchestra and the class of the person concerned. In addition, private contacts were among them, says the Basel health department to Blick. However, the decision was made not to quarantine the audience present at the concert. From an epidemiological point of view, that would not have been proportionate, the canton says. There had been no close contact with the affected person.

At this time, according to the health department, there is no need for additional precautions for all other classes and people who had no direct contact. Daily class pools are currently positive, it continues. However, no further indications of the Omikron virus have been found so far. The health department will inform if additional measures become necessary.

I po ovome bi se reklo da je omikron dosta jako krenuo u Engleskoj, pogotovu što je delta tamo živa i zdrava sa četrdesetak hiljada novih slučajeva dnevno.

The omicron variant spread to at least 10 U.S. states after New Jersey, Pennsylvania, Missouri, Maryland and Nebraska reported infections on Friday. “We absolutely have community spread” of the new strain in the U.S., Anthony Fauci, President Joe Biden’s top medical adviser, said on Bloomberg Television.

Omicron Up Close: South Africa’s Experts Tell Their Stories
The panicked reaction across much of the world to the omicron variant comes with a scramble for information. In South Africa, the country where omicron was first identified and where cases are jumping, scientists and doctors describe what they are seeing. 

Here are highlights from several interviews and a briefing.

Marc Mendelson, the head of infectious diseases at the University of Cape Town, who also works at Groote Schuur Hospital, where the world’s first heart transplant took place:

• “Anecdotally, we are seeing a lot of reinfections. What we don’t know at the moment, because we haven’t got the data yet, is how many of those people are un-vaccinated versus the vaccinated.”
• “While people are freaking out, the other thing to stress is that if you look across the variants, the vaccines have protected against severe disease, hospitalization and death. And really, looking at the omicron mutations, though there are an awful lot of them, there’s nothing really to indicate that the ability of vaccines to fight this is going to be affected to a very great extent.”
• “In truth, it doesn’t want to kill you, it wants you to stick around.”
• “The only ones putting their hand on their hearts and telling the world don’t worry, this is going to be mild, haven’t learned enough humility yet in the face of this virus.”
• “It’s always nice to hope, but don’t set everything on this because I think your hopes could be dashed.”

Richard Friedland, chief executive officer of Netcare Ltd., which operates the largest private health-care network in South Africa:

• “If in the second and third wave we’d seen these levels of positivity to tests conducted, we would have seen very significant increases in hospital admissions and we’re not seeing that. In our primary care clinics it is mainly people under 30-years-old.”
• “So I actually think there is a silver lining here and this may signal the end of Covid-19, with it attenuating itself to such an extent that it’s highly contagious, but doesn’t cause severe disease. That’s what happened with Spanish flu.”
• “We are seeing breakthrough infections of people who have been vaccinated, but the infections we’re seeing are very mild to moderate. So for health care workers who have had boosters, it’s mostly mild. I think this whole thing has been so poorly communicated and so much panic generated.”
• “It’s early days, but I’m less panicked. It feels different to me on the ground.”

Shabir Madhi, a vaccinologist from the University of the Witwatersrand, who led trials of both AstraZeneca Plc’s and Novavax Inc.’s shots in South Africa:

• “Omicron seems to be moving at a faster speed than delta, but at the same time what seems to be happening is that our hospitalization rate is somewhat more muted.”
• “Vaccine or past transmission create T-cell immunity, which are good at protecting against severe disease and death. The mutations of the virus very likely make it more successful against antibody activities, but it seems like there may well be preservation of the T-cell immunity.”
• “I’m optimistic that in this resurgence, while the total number of cases will probably be greater, hospitalizations and deaths will be lower than what we experienced during the course of any of the first three waves. And that is, because right now in South Africa, all indications are that 75% to 80% of people were infected with the virus during the course of the first three waves. That is probably going to equip those individuals -- not to resist infection -- but rather prevent progression of infection to severe disease.”

Anne von Gottberg, a clinical microbiologist at South Africa’s National Institute for Communicable Diseases:

• “All the data has shown that children have a less severe clinical course and we’ve had some anecdotal reports from hospitals in South Africa, that yes, they are seeing a few more children in some of the hospitals and are admitting them, but many of them have an uncomplicated clinical course during the few days that they are in hospital.”
• “We monitored reinfections for the beta and the delta waves and we didn’t see an increase in reinfections over and above what we expect when the force of infection changes, when a wave starts. With omicron, we are seeing an increase in reinfections.”
• “This virus may be similar to delta in its ability to spread or in being contagious. However, it’s the susceptibility of the population that is greater now because previous infection used to protect against delta and now, with omicron, it doesn’t seem to be the case.”
• “However, we believe that with the reinfections the disease will be less severe and the same would hold for those that are vaccinated. So that would be good news.”

Adrian Puren, acting executive director of the NICD:

• “While there are large numbers of cases and evidence of increased hospitalizations, large-scale sequencing would show if this variant is starting to fully displace the delta variant. Current evidence shows that omicron accounts for about 75% of the variants in circulation overall.”
• “If it does displace the delta variant, we’d need to see if this is the result of immune evasion or because of increased transmissibility.”
• “We had the beta variant, which was more about immune evasion and we had the delta, which was more about increased transmissibility. But reinfection data shows that transmissibility is a major contributor, so we are still trying to see if omicron fits more into immune evasion primarily or more into increased transmission or both. Reinfection data points to immune evasion.”

Leon Geffen, a general practitioner in Cape Town’s Sea Point suburb and director of the Samson Institute for Ageing Research:

• “We are seeing a massive upsurge in the total number of cases,” he said. “People are mostly presenting with coughs and upper respiratory tract infections.”
• “Most people I have seen or spoken to have been vaccinated.”

Anthony Smith, a general practitioner in Cape Town:

• “It was like a tap being turned on from Thursday or Friday last week. It’s been mostly young people, but there have been some older people, probably around 20%.”
• “Most of the kids have got it at communal events. They are from a younger demographic and presenting with milder symptoms, mainly sore throats and respiratory phenomenon. But, even in older people, it’s been relatively mild.”
• “No-one has been even close to being seriously ill. But it’s probably too early to tell if this will be a milder variant.”

Viral genomes deduced from these 2 SARS-CoV-2‒positive cases differed only by 1 nt. Retrospective investigation, including closed-circuit television camera footage, confirmed that neither case-patient left their room during the quarantine period. No items were shared between rooms, and other persons did not enter either room. The only time the 2 quarantined persons opened their respective doors was to collect of food that was placed immediately outside each room door. The only other time they might have opened their doors would be for RT-PCRs, which were conducted in 3-day intervals. However, because these 2 case-patients arrived 1 day apart, it is unlikely that they would be tested on the same day. Airborne transmission across the corridor is the most probable mode of transmission.
