NSW Chief Medical Officer Dr. Kerry Sand today confirmed that there is concern about the mutation, but it is not circulating in the community.
“I have been advised that we have received two passengers who have returned to the UK with the specific mutations you mention,” Dr. Sand replied to a question about the strain.
“Can I make it clear that the Avalon cluster strain does not have those mutations?
“But the important thing is that we treat the final decision process to ensure that they do not contact all people and that there is no exposure risk to any resident of New South Wales.”
It is believed that about 60 per cent of cases in London are due to this new mutation, and the capital now has the highest infection rate in the UK.
“There is no evidence that this is a very serious or serious illness,” said British Prime Minister Boris Johnston.
He said there was no evidence that vaccines against the new strain would be less effective.
The UK Chief Medical Officer Chris Witty has warned the World Health Organization that the new variant identified this week appears to be accelerating the spread of COVID-19.
The government’s scientific advisers came to that conclusion based on preliminary modeling figures, and they are constantly analyzing the available data, he said.
Viruses evolve involuntarily, and scientists have discovered thousands of different mutations in the virus samples that cause COVID-19.
But many of these changes have no effect on how easily the virus spreads or how severe the symptoms are.
UK strain ‘must be kept in context’
Paul Kelly, Australia’s chief medical officer, said there had been thousands of mutations in the corona virus, and that the new mutation “must be put into the environment.”
“This particular strain, especially in circulation in the southeastern UK at the moment, has specific mutations related to spike protein because of the way it enters the virus cells and the specific part of the vaccine that attacks the virus, all vaccines are related to spike protein,” said Professor Kelly.
“There is no conclusive evidence that this is a significant change.”
He said the high prevalence rates in the south-west of the UK could be due to a number of factors, including people moving before Christmas and it being winter.
Professor Kelly noted that anyone entering the UK from the UK would go for hotel isolation.
