COVID-19 is a new variant of the very common viral family known as coronavirus, which can lead to respiratory tract infections, from the common cold to more serious diseases, such as severe acute respiratory syndrome (SARS). Although coronavirus is most commonly found in animal-like cattle, cats, and bats, in some cases, coronavirus can be transmitted and transmitted among humans, such as COVID-19 and SARS, of which nearly 8000 people were sick when they broke out in 2003.

According to the information currently shared by the new crown virus database GISAID, the number of mutation sites of the new crown virus Omi Keron mutant strain is significantly more than that of all the new crown virus mutant strains that have been circulating in the past two years, especially in the virus spike (Spike) protein mutations. . It is speculated that there may be three reasons for its emergence:

(1) After being infected with the new coronavirus, patients with immunodeficiency have undergone a long period of evolution in the body to accumulate a large number of mutations, which are transmitted by chance;

(2) a certain animal group infection New coronavirus, the virus undergoes adaptive evolution during the spread of animal populations, with a higher mutation rate than humans, and then spills into humans;

(3) This mutant strain has continued to circulate for a long time in countries or regions where the mutation monitoring of the new coronavirus genome is lagging. , Due to insufficient monitoring capabilities, the intermediate generation viruses of its evolution could not be detected in time.

The genome analysis of the Omi Keron mutant strain showed that its mutation site does not affect the sensitivity and specificity of mainstream nucleic acid detection reagents in my country.

The mutation sites of the Omi Keron mutant strain are mainly concentrated in the highly variable region of the S protein gene.

The nucleic acid detection reagent primers and probe-target regions were published in the eighth edition of the "New Coronavirus Pneumonia Prevention and Control Program" (China CDC Virus The ORF1ab gene and N gene released by the disease to the world).

However, data from multiple laboratories in South Africa suggests that nucleic acid detection reagents that detect the S gene may not be able to effectively detect the S gene of the Omi Keron variant.

Yes,’ if you’re going to a public place, it’s recommended to wear a mask. As long as the nose and mouth are covered, a scarf, handkerchief, or homemade non-medical mask can play a protective role.

It’s really important to wash your hands before and after putting on a mask.
