The outbreak of the new variant has worsened, and the number of cases in Sydney has soared! Australia discovers new coronavirus mutation
Recently, the new crown epidemic has begun to quietly rebound again! Australia's epidemic figures have risen again! Omicron subvariant BA2 "fight"! Cases may "more than double" in 6 weeks! Is a new wave of epidemic coming? At the same time, the study found that the virus mutation in Australian new crown patients! Existing drugs may soon expire!
In the latest period of time, the daily epidemic figures in New South Wales and Victoria have increased.
According to the Ministry of Health, 16,288 new cases of new crown were confirmed in NSW today, of which 9,482 were RAT-positive and 6,806 were PCR-positive.
This is the highest number since January 27. 4 people have died from the new coronavirus.Victoria reported 7779 new cases of COVID-19 today, including 5270 RAT positives and 2509 PCR positives.8 people unfortunately died from the new crown virus.
On March 7, there were only 5,645 cases in Victoria, and now it has jumped to nearly 8,000 cases.
As for why the number of cases has risen significantly, recently, the Ministry of Health finally gave an explanation.
Health authorities are concerned about the spread of the Omicron subvariant, which is believed to be behind the rise in NSW cases, according to Australian media. NSW Health Minister Brad Hazzard told the NSW budget estimate hearing today that the BA2 sub-variant is more contagious than the BA1 variant and is emerging as the dominant Omicron variant in the community. Hazzard said preliminary data from the University of NSW suggested cases could more than double in six weeks. The health minister said he was concerned that community willingness to get a booster shot was low at just over 56 per cent, a sign that the public has lost sight of the coronavirus. BA2, known as a "stealth" variant of the virus, has been circulating in Australia since late January. The number of cases in NSW is expected to rise after restrictions, including mask orders, were eased on February 25. NSW Premier Dominic Perrottet announced on February 17 that the restrictions would be eased, saying the surge in infections should not be seen as a "measure of success or failure". NSW's Deputy Chief Health Officer Marianne Gale said an increase in socialising, major events and a reduction in the number of people wearing masks had contributed to the rise in infections. Dr Gale said evidence from overseas suggested that the BA2 variant could rapidly overtake the BA1 variant as the predominant circulating subvariant.
Dr Gale said it was believed that the BA2 variant was more contagious, but whether it was more severe was unknown.
"The initial and early projections from the UNSW team ... do suggest that we have the potential to see an increase in the number of cases in March, April and May," she said.
"We don't know exactly how high this peak will be, how long it might last, or when exactly it will come."
"Every day people die from the coronavirus, and we have a lot of people in our hospitals," Hazzard said."We're really concerned about what we're seeing."
Not only is the rapid spread of BA2 sub-variants worrying, but recently, we also heard bad news:Australia discovers new coronavirus mutation!
Drug-resistant strains of the virus have emerged in Australia's new crown patients, with calls for increased surveillance to curb the spread, the Herald Sun reported.
A major drug used to fight severe cases of the new coronavirus has caused the virus to mutate, posing a risk of community spread, the report said.
If this happens, the elderly and immunocompromised patients will not be able to be treated with the drug Sotrovimab.
University of Sydney researcher Dr Rebecca Rockett studied 100 COVID-19 patients in NSW's Western Sydney Local Health District health facilities during the Delta outbreak between August and November 2021.
She found that in four of the patients, the virus in their bodies mutated within six to 13 days, and the treatment was no longer effective at controlling the infection.
Samples of the mutated virus taken from these patients were able to grow in lab dishes, demonstrating that the new version of the virus was able to spread to others. "The concern is that after these patients developed resistance, the virus was still alive and persisting in them," Dr. Rockett said.
"What we don't want to see is that some people in the community develop resistance that they can pass on to others, and that makes the drug useless, not just for that person, but for that person," she said. The people they spread the virus to are also ineffective."
Many of the patients in the study had severe immune deficiencies, and Dr. Rockett said one theory for the emergence of the Delta and Omicron variants of the virus is that they arose in these individuals.
