Israel has banned foreigners from entering the country for two weeks, while Britain has revised its entry requirements after Omicron was found. Two new coronavirus mutated in travelers returning from southern Africa
Germany and Italy have already detected the virus in their countries.
Mr Boris Johnson Prime Minister of the United Kingdom Announced to reporters on Nov 27 that it will bring the mandatory wearing of masks in public transport. and in the store to use again Speeding up needle vaccination to encourage people and switch back to allow travelers entering the country to undergo PCR testing instead of the Rapid Antigen Test
“We will require everyone entering the UK to undergo a PCR test within two days of arrival and self-isolate until a negative test result comes out.”
PCR testing (PCR) stands for polymerase chain reaction or polymerase chain reaction. It is a method of testing for COVID-19. the most accurate available today by detecting ribonucleic acid or RNA (RNA) of the coronavirus causing COVID which is the same molecule as DNA
PCR testing must be done in a scientific laboratory (lab) to detect very small amounts of RNA. and usually results come out within 24 hours.
Mr Johnson added: Those who come in contact with someone infected with Omikron are required to self-isolate for 10 days, and these measures will be reviewed three weeks after they come into force.
British public health officials said on November 27 that two people from southern Africa had been confirmed in the country. Omicron infection
“Worrying” species
The World Health Organization (WHO) announced on Nov. 26 that a new type of coronavirus has been found in southern Africa. It is a species that is “worrying”, given the name Omicron.
The WHO also said the virus had mutated at several points. And preliminary evidence suggests there is a risk of recurrence.
South Africa reported the virus to the World Health Organization on Nov. 24 and confirmed cases in Botswana, Belgium, Hong Kong and Israel, prompting several countries to impose bans. or restricting travel between those countries and southern African countries
Omicron is considered a COVID-19 virus. The type 5 mutant the World Health Organization classifies as a species of concern. after alpha, beta, gamma and delta strains
The vagueness of the severity of this species causing international countries, including Thailand, to issue measures to control travel from countries in South Africa
Most recently, Prime Minister Naftali Bennett issued a statement on Nov 27 that Israel will ban foreigners from entering the country for 14 days starting at midnight on Nov 29. must be quarantined In the meantime, the government hopes to have more information on how effective the existing vaccine is in combating the mutant.
Mr Bennett said he would reintroduce anti-terrorism phone tracking technology to prevent the spread of the mutant.
Found in Germany, Italy
The German Ministry of Health said on November 27 that Bavarian authorities had found the virus in two people entering the country via Munich airport on November 24 and are currently quarantined. But the ministry did not say whether the two were from South Africa or not.
In Italy, the National Institute of Public Health states that One new case of coronavirus found in Milan traveling from Mozambique
The Czech public health agency said it was proving a suspect from Namibia had been infected with the mutation.
Chris Whitty, British Chief Medical Officer Standing at a news conference with Mr Johnson, he said that although there was still much uncertainty about the effect of the mutant, “there is a reasonable chance the strain could escape the vaccine’s capacity to some degree.” “So British authorities are mobilizing 2nd dose vaccinations for teenagers and 3rd dose for adults aged 40 and over.
how worried
Previously, health officials of South Africa The spread of a new COVID-19 virus with severe mutations in dozens of genes has been detected. raising fears that this type of mutant may spread easily And it’s more dangerous than any other species the world has ever encountered.
The SARS-CoV-2 strain It was originally scientifically known as B.1.1.529, before WHO named it in Greek alphabetical order Omicron.
Authorities found the outbreak mainly in South Africa’s Gauteng province. In addition, the infection was found in Botswana. It also found another case of the infected person traveling from South Africa to Hong Kong via direct flight.
Professor Tulio de Olivera, Director of the South Africa Center for Innovation and Epidemic Response It said the new coronavirus has 50 gene mutations in total, which is extremely unusual and sets it apart from any other mutated coronavirus that has ever been found.
- This unexpected mutation It is classified as a protein mutation on 32 viral spine segments, one of which is of paramount importance. In being the key the virus uses to unlock the door to human cells.
They also found mutations in the receptor binding domain, which the virus uses to bind to human cells in up to 10 locations, while the deadly coronavirus, the Delta strain, has been found. There are only two mutations in this section.
Experts say A severe mutation of this nature Probably caused by infection in only one patient. by the body of the patient that is the source of the mutation unable to fight resistance against germs
