A new coronaviruses variant has been detected in South Africa, which scientists say is a concern because of its high number of mutations and rapid spread among young people in the most populous province.
The coronaviruses evolve as it spreads and many of them die out. It can take time to sort out whether a new variant will have a public health impact.
South Africa has seen a rise in new infections.
He said that there has been a spike in cases over the last few days, and that the new variant appears to be driving it. Scientists in South Africa are trying to figure out how much of the new cases are caused by the new variant.
Travelers from South Africa have found the new variant in Hong Kong.
The new variant of the World Health Organization may be given a name from the Greek alphabet.
The British government banned flights from South Africa and five other southern African countries at noon on Friday, and anyone who had recently arrived from those countries would be asked to take a coronaviruses test.
The new variant may be more transmissible than the dominant strain, and the vaccines that we currently have may be less effective against it, according to the U.K. Health Secretary.
The new variant has a correlation of new genes, according to the Network for Genomic Surveillance in South Africa, who has tracked the spread of the delta variant in the country.
The high number of genes is a concern for immune evasion and transmissibility.
He said that the new variant has many, many more changes, including more than 30 to the spikeProtein that affects transmissibility. The variant could be spreading very fast. Pressure is expected to start in the healthcare system in the next few days.
A team of scientists from seven South African universities are studying the variant. He said that they have 100 whole genomes of it and expect to have many more in the next few days.
He said that they were concerned by the jump in evolution. The good news is that it can be detected by a test.
South Africa recorded just over 200 new confirmed cases per day in the past week, but in the last week the daily new cases have increased to more than 1,200. On Thursday they went up to 2,465.
The health minister said that the first surge appeared to be from student gatherings at universities in the area. Scientists discovered a new variant of thegenomics after studying the rise in cases.
The professor of clinical microbiology at the University of Cambridge said that this is a variant that they must be very serious about. It has a high number of spikes that could affect the immune response.
Gupta said that scientists in South Africa need time to figure out if the surge in new cases is related to the new variant. He said there was a high chance that it was the case. South African scientists have done a great job of bringing this to the attention of the world.
South African officials had warned that there would be a new resurgence in the middle of December and had hoped to get many more people to bevaccinated.
The number of shots being given per day is less than the government's target of 300,000, and about 40% of South Africa's adults have been vaccined.
Nicholas Crisp, acting director-general of the national health department, said that South Africa currently has about 16 million doses of vaccines by Pfizer and Johnson & Johnson, and that 2.5 million more will be delivered in the next week.
Crisp said that they are getting in vaccines faster than they are using them. For some time now, we have been deferring deliveries, not decreasing orders, but just deferring our deliveries so that we don't accumulate and stockpile vaccines.
More than 89,000 deaths have been recorded in South Africa, which has a population of 60 million.
The delta variant is the most infectious and has crowded out other once-worrying variants. The world's biggest public database shows that more than 99% of the submitted sequence are delta.
Scientists are concerned about a new variant of COVID-19 being found in South Africa.
