A new strain of coronavirus – called B.1.1.529 – has been identified in South Africa, where authorities say it is alarming. Fears that the new crisis could lead to a global catastrophe, disrupting health systems, fleeing vaccinations and disrupting efforts to revive economies and borders, posed a threat to global markets on Friday.
Here is what we know so far:
What is the difference between the two?
Scientists say that B.1.1.529 carries a number of mutations in its spike proteins, which play a key role in the entry of the virus into body cells. It is also what the vaccine controls. Researchers are still trying to determine if it is more contagious or deadly than in the past.
Where did it come from?
There are so many fantasies so far. A scientist at the UCL Genetics Institute in London said this happened at a time when an uninfected person could become infected, possibly with a person living with HIV / AIDS. South Africa has 8.2 million people living with HIV, the largest in the world. The beta mutation, a change that was announced last year in South Africa, may have come from a person living with HIV.
How has it spread?
As of Thursday there were about 100 people diagnosed in South Africa, which has been a major problem among the new infections. Preliminary results from PCR showed that 90% of the 1,100 new cases reported Wednesday in South Africa, including Johannesburg, were the result of the change, according to Tulio de Oliveira, a professor of bio-informatics who runs genetic engineering in South Africa. universities.

In neighboring Botswana, officials filed four cases on Monday of vaccinated people. In Hong Kong, a traveler from South Africa was diagnosed with the virus, and another case was identified as a solitary confinement in a hotel room across the hall.
What did you do?
News of the new markets hit Friday, with travel-related shares in Asia falling sharply as investors anticipate negative reactions that could affect travel. The UK has temporarily banned flights from six African countries, and Australia has said it will not restrict the restrictions on travelers from southern Africa if the situation worsens. India increased the visibility of travelers from South Africa, Botswana and Hong Kong. The yen, often viewed as a safe haven, rose 0.4% against the dollar, while the South African rand depreciated by about a year.
How difficult is this?
That’s the first thing to say. The World Health Organization estimates that there are at least 100 new types of vaccines available, which could increase the time it takes to study and how modern vaccines work against them. Viruses change all the time, and mutations sometimes make the virus weaker or sometimes make them more effective at preventing antibodies and infecting people.
What should we look for then?
The WHO convened a meeting Friday to discuss B.1.1.529 and to determine whether it will be legally recognized the type of interest or concern. If it does, it will receive the Greek name under the WHO name system, possibly the letter “nu.” Governments should also take action on border control and travel in the light of these changes.
