A small percentage of people living with the virus Omicron coronavirus should receive medical care in comparison to the Delta crisis, according to health data from South Africa and Denmark.
Their findings from various research groups offer hope that there will be fewer infections than those caused by other viruses, but the researchers warned that Omicron’s disease could disrupt health services.
The decline in potentially life-threatening infections may have been caused by the high number of Omicron, compared to other species, infecting people who have been vaccinated or who have been infected in the past, experts have confirmed.
Non-vaccinated groups remained at high risk but due to the high incidence of Omicron-induced infections, the proportion of all cases that led to the spread of the disease was low compared to other species. This problem now causes a lot of Covid-19 cases in several countries, including the US.
A South African study, conducted by the National Institute for Communicable Diseases in the country, found that among those tested in October and November, Omicron cases were estimated to be 80 percent lower than those found with Delta in hospital. . including age, health problems and previous illnesses. But researchers confirmed that they did not consider vaccines in the study, and that most of the previous infections were unreliable.
A second review from the same research team, this time monitoring the vaccine status, found that after being discharged from the hospital, Omicron and Delta cases from recent weeks had a similar chance of getting into serious trouble. The review included more than 10,000 cases of Omicron and more than 200 hospitalizations.
“Something is happening. . . according to Omicron vs Delta’s immune response varies, ”said Prof Cheryl Cohen, an epidemiologist at the University of the Witwatersrand and co-author of the study.
He said the findings showed that Omicron-induced infections were “very low” and that the immune system from Omicron’s T-cell and B-cell “center” to serious infections “even collapsed.
Cohen said the burden on hospitals had allowed South Africa to tackle the Omicron waves without a hitch but warned that the findings would not apply to western-occupied countries.
“What is it about [Omicron] It means that actual numbers, if those numbers are too high, could lead to serious public health problems even if the risk of serious illness is minimal, “he added.
Separately, Danish data showed that of the people who tested between November 22 and December 15, Omicron cases were three times less likely to be hospitalized than cases of other types. But experts have warned that the increasing number of Omicron outbreaks among minority groups could be disrupted.
“It is the young and vaccinated people who are infected with the Omicron virus, and if we change this, we will see no evidence that Omicron should cause less disease,” said Henrik Ullum, chief of Statens Serum Institut, a health organization in Denmark. at a press conference Wednesday.
But while there is no evidence to suggest any reduction in risk, this does not prevent Omicron from having a small impact on the population, given the high number of cases among people who are immune to serious illness through early infection or vaccination.
“Because of Omicron’s immune system, this [of fewer cases being hospitalised] continues to monitor population growth, “said Prof Samir Bhatt, professor of mechanical engineering and public health at the University of Copenhagen and a member of the UK government’s SPI-M model team.
The UK government anticipates new developments in Omicron’s threat before choosing other restrictions in England. But Bhatt said the UK approach is “Panglossian”, adding that it “continues beyond the expectations offered by the slightest hint”.
“I see that the number of hospitals is going to decrease because the vaccine appears to be safe,” said Prof Thea Kolsen Fischer, chief of viral and microbiological diseases at the Statens Serum Institut.
But he added that policymakers need to “take a little precaution to keep the matter afloat” because “within a few weeks” before the changes become apparent.
“I’m afraid that because of Omicron’s disease. . . “What we are seeing now will be very different in just two weeks,” he said.
On Sunday, Denmark introduced a number of options that should be The spread of Omicron, including the closure of theaters and museums and the limits of population growth in bars, restaurants and shopping malls.
Prof Peter Garred, a medical doctor at Copenhagen’s Rigshospitalet, Denmark’s largest hospital, said a major downturn could force countries, such as England and the US, to impose “almost” sanctions.
“The question of whether Omicron was gentle or not had little effect on the new negotiations [in Denmark], ”Says Garred. “The government is looking forward to the crisis because the risks of the disease are increasing, no matter how difficult it is.”
Cohen of the University of the Witwatersrand said Omicron’s waves could “come out differently” in the north of the world because of winter but also said that good signals from South Africa “are very important to other countries and the way they do it”.
“Most people have a previous illness or a vaccine or both now,” Cohen said. “If it continues, it is a fact that all countries will see the same for us.”
