scientists were soon worried about this new variant because of its high number of mutations. They are concerned that vaccines designed for previous new crown variants may not be effective

according to the National Institute of infectious diseases of South Africa, 22 known cases of b.1.1.529 had appeared as of Thursday. The virus was also found in the northern neighbouring Botswana and Hongkong, China. p>

“this variant really surprised us,” Tulio de Oliveira, director of KwaZulu Natal research and innovation sequencing platform, said at a news conference on Thursday. “Its evolution has made a big jump, with many more mutations than we expected, especially after the very serious third podelta variant.”

it is unclear whether these mutations will translate into a more dangerous, transmissible and anti vaccine covid form. Covid continues to mutate, many of which do not have a substantial impact on the virus. Oliveira pointed out that who experts will hold a meeting on the new variant on Friday. He expects the variant to get a Greek name after beta and delta

“we don’t know much about this,” Maria van kerkhove, technical director of who covid, said in a live broadcast on Thursday, “What we know is that this variant has a large number of mutations. What is worrying is that when there are so many mutations, it may affect the behavior of the virus. It will take us a few weeks to understand the impact of this variant.”

on Thursday, British health secretary Sagid Javed announced that South Africa and five other southern African countries, namely Namibia, Zimbabwe, Botswana, Lesotho and Aars Waed Ni, will enter the red list of tourism in Britain. Flights to these countries have been stopped, and travelers returning to Britain from these countries will have to be quarantined. Israel has done the same. What’s more, there is a sixth country on its list – Mozambique.

a new variant has emerged in Africa, which is not surprising to many epidemiologists. The virus that causes the new crown will mutate during replication. In places with low vaccination rate and a large number of cases, the new variant is more likely to appear, as in Delta in India. And Africa The country’s vaccination rate is low, and most of the population is too poor to miss vaccination and cannot seek medical help. Although South Africa is the richest country in Africa, the dual vaccination rate there is only about 23%
