The results of false virus synthesis and experimental verification of the key mutation sites confirmed that the Jiangsu Bioperfectus Technologies Co.Ltd(688399) New Coronavirus 2019-nCoV nucleic acid detection kit (fluorescence PCR) did not miss the target and missed detection for the above mutant strains, which could effectively ensure the specificity, accuracy and sensitivity of the detection.
In addition, in view of the latest covid-19 virus variant, the reporter of Beijing Daily learned from covid-19 vaccine manufacturer Kexing that Kexing is highly concerned about the relevant information of covid-19 virus Omicron variant and has started to actively collect and obtain the relevant information and samples of the new variant through the global partner network, evaluation and research will be carried out as soon as possible to understand the impact of Omicron strain on the existing inactivated covid-19 virus vaccine and the necessity of developing variant vaccine.
Biden announced travel restrictions on eight African countries
The White House issued a presidential announcement 26 days, announced the implementation of travel restrictions to 8 African countries, such as South Africa, Botswana, Mozambique, Namibia and Lesotho.
The policy will come into effect on November 29, US Eastern time: non US citizens who have stayed in the above-mentioned countries 14 days before going to the United States will be restricted.
Recently, many countries in South Africa and Botswana reported a new COVID-19 variant strain called "B.1.1.529". The strain has many variations and may have stronger resistance to the vaccine, which has attracted the attention of researchers.
The World Health Organization named the mutant strain "Omicron" after evaluation on the 26th and listed it as the global "concern variant" of covid-19 virus.
U.S. President Joe Biden said in a statement on the same day that he had heard a briefing on the new mutant strain by fudge, the chief medical adviser to deal with the covid-19 epidemic. The U.S. travel restriction policy is "preventive measures taken before obtaining more information".
While calling on the American people to be vaccinated as soon as possible, Biden said that the emergence of new mutant strains makes it clearer than ever that the covid-19 pandemic will not end until vaccination is universal around the world.
In an interview with US media on the same day, Fudge said that some variants of the new mutant strain "caused some concerns", including "possible enhanced infectivity and possible vaccine resistance". Researchers are trying to determine whether the current vaccine is effective against the new mutant strain.
The Washington Post quoted White House officials as saying that it may take two weeks for American medical researchers to fully understand the effectiveness of the vaccine against the new mutant strain.
Earlier, European Commission President von delaine had warned that Member States should take "emergency braking" action to interrupt flights with southern African countries and that "Europe needs rapid, decisive and concerted action".
At present, France, Italy and Britain have grounded flights from southern African countries.
two cases of "Omicron" infection in the UK
On November 27 local time, British health secretary Javed said that two cases of infection with the new variant of covid-19 virus "Omicron" were found in Britain. Javed said the two cases were in Chelmsford and Nottingham and were related to each other. At present, the two patients are self isolated with their families. Targeted virus testing will be carried out in areas where cases are found.
Omicron, the new covid-19 virus variant first found in South Africa and other countries, continues to spread in more countries and regions outside Africa. According to the Russian satellite news agency, Germany and the Czech Republic each reported suspected cases of the mutant strain Omicron.
it is reported that in the Czech side, a suspected case had been in Namibia for some time; In Germany, a suspected case has just returned to Germany from South Africa.
infectious or enhanced by 500%!
Previously, the who issued a statement that B.1 1.529 is listed as "variants to worry about" and named Omicron. This means that experts from the WHO virus evolution technology advisory group believe that the new variants have higher transmission or pathogenicity, or may reduce the effectiveness of current diagnosis, vaccines and therapies.
Previously, four variants were incorporated into VOC by who, including alpha, beta, gamma and delta with the strongest transmission power, and Omicron became the fifth. Who points out that preliminary evidence suggests that this variant may increase the risk of reinfection in the population compared with other VOCs.
On the 26th local time, Ding Liang, a Chinese American epidemiologist and senior researcher of the American Federation of scientists, pointed out that compared with the delta variant, the number of "bad thorn mutations" of the new variant is twice as much as that of the delta variant, " b.1.1.529 variant may have 500% strong infectivity, which is the most shocking statistics ".
On the 26th, 2828 new cases were confirmed in South Africa. According to South African health officials, diagnostic tests by scientists show that the new variant may cause up to 90% of new cases. Early studies have shown that the R value of Omicron is 2 (each person can infect 2 people).
"We have seen significant changes in the situation of patients with the recent covid-19 epidemic," said Rudo mathivha, director of the intensive care unit research center of baragwanas hospital in Soweto, South Africa, AP reported "Many young people in their 20s to 30s suffer from moderate and severe diseases, and some need intensive care. About 65% of them have not been vaccinated, and most of the others have only been vaccinated."
