The picture shows that compared with the delta strain of the new coronavirus mutant virus, the Omicron strain has more spike protein mutations. These variations are diverse, and most of them are located in areas that interact with human cells.


Researchers said that the new coronavirus has further adapted to the human body through mutation, but it does not necessarily mean that it has become more dangerous.

British Prime Minister Johnson held a press conference on the same day, announcing that “targeted measures” will be taken to deal with new mutant strains.

These measures include: all international travelers need to undergo a nucleic acid test after arriving in the UK, and need to self-isolate before getting a negative result; those who have been in close contact with a confirmed case of the “Omicron strain”, regardless of whether they have been vaccinated against the COVID-19 vaccine.

Need to self-isolate for ten days; strengthen the regulations on wearing masks when shopping in stores and on public transportation; consider vaccinating more people with the COVID-19 vaccine booster and shorten the interval between the second dose of vaccine.

The Ministry of Health of the Netherlands announced on the 27th that a total of 61 passengers on the two flights from Johannesburg, South Africa to Amsterdam, tested positive for the COVID-19 virus on the 26th.

The virus samples are being analyzed to confirm whether there is an “Omicron strain.” The Netherlands Institute of Health said that it is “almost certain” that some of these 61 people were infected with the “Omicron strain.”


The Czech Republic reported on the 27th a case suspected of being infected with the “Omicron strain”. The case had previously been to Namibia, an African country.
