Regarding Omicron, the latest answer from the National Health Commission is here!

Recently, multiple cases of Omicron variant infection have been reported in many places, which has aroused widespread concern
.

1.
Discovery and prevalence of Omicron variants

On November 9, 2021, South Africa detected a new coronavirus variant for the first time from case samples
.

The Omicron variant was first imported into Hong Kong, China on November 27, 2021, and was first imported into mainland China on December 9
.

2.
Transmissibility of Ormicron Variants

Epidemiological data from multiple countries suggest that the transmissibility of the Omicron variant is enhanced compared with other variants
.

3.
The effect of existing vaccines on the prevention of Omicron variant infection

The existing research results show that the Omicron variant does not completely escape immune escape from the existing vaccine; the existing vaccine still has a certain protective effect on the Omicron variant, but its ability to prevent infection is limited.
There is no increase in the severe disease rate and mortality rate caused by the Omicron variant strain.
For the Omicron variant strain, the existing vaccines are still effective in preventing severe illness and death
.

　　4.
The impact of Omicron variant strains on existing nucleic acid detection reagents

　　The genome analysis of the Omicron variant shows that the mutation site is not located in the target region of nucleic acid detection reagent primers and probes published in the eighth edition of China's "New Coronavirus Pneumonia Prevention and Control Plan", and does not affect China's mainstream nucleic acid detection reagents.
sensitivity and specificity

　　5.
Measures taken by relevant countries and regions

　　In view of the rapid global epidemic trend of Omicron variants, the United States, the United Kingdom, Russia and the European Union have recently recommended that the public strengthen daily hygiene protection (washing hands, wearing masks and social distancing), and the health department strengthens disease surveillance and vaccination.
In particular, the booster shot of the new coronavirus vaccine for front-line medical staff
.

　　6.
my country's countermeasures

　　China's general strategy of "foreign defense against import, internal defense against rebound" and the general policy of "dynamic clearing" are still valid for Omicron mutants
.

　　7.
WHO Recommendations for Response to Omicron Variants

　　The World Health Organization recommends that all countries strengthen the monitoring, reporting and research of the new coronary pneumonia virus, and take effective public health measures to block the spread of the virus
.

　　8.
In the face of the Omicron variant, the public's precautions in their daily work

　　(1) Wearing a mask is still an effective way to block the spread of the virus, and it is also applicable to the Omicron variant
.

　　(2) Do a good job in personal health monitoring
.

　　(3) Reduce non-essential travel
