Omicron 奥密克戎 （最新的来自南非的新变异毒株）

news content:

So today WHO's technical advisory group on virus evolution met on discuss the variant B.1.1.529 to discuss what we understand about this variant.and if it should be classified as a variant of interest or variant of concern.Based upon the information that we have,particularly from South Africa. They have advised WHO that this variant should be classified as a variant of concern.

so today we are announcing B.2.2.529 as a variant of concern named Omicron。So,Omicron B.1.1.529 is named as a variant of concern.because it has some concerning properties.This variant has a large number of mutations and some of these mutations have some worrying characteristics.

Right now,there are many studies that are underway.There's a lot of work that is ongoing in South Africa and in other countries to better characterized the variant itself in terms of transmissibility ,in terms of severity.and any impact on our counter measures like the use of diagnostics,therapeutics of vaccines。

So far,there's little information. But those studies are underway,so we need researches to have the time to carry those out.And WHO will inform the public and our partners and our member states as soon as we have more information.Once a variant is classified as a variant of concern.It's really important that we have good SARS-COV-2 surveillance around the world. including better genomics sequencing。Because we want to be able to detect this variant where it is circulating It is also really important that studies are undertaken in the field to look at any clusters.and also the studies that are needed in the lab.to look to see if there's any changes in severity.any changes in our impact on diagnostics ,therapeutics or vaccines.The technical advisor group for a virus evolution will be meeting regularly about Omicron.It will take days to weeks for some of these studies to be undertaken.It's really important that these studies are done and they're done comprehensive.

As soon as we have more information,we will take that information public.But it's important to know that there's a lot that you could do to keep yourself and your loved ones safe.we understand that people are concerned.The good thing is that we have monitoring systems around the world to detect these variants very quickly.This variant was detected a few weeks ago,and already scientists are sharing research with us.information with us so that we can take the action.

What's really important as an individual is to lower your exposure.The measures ,these proven public health measures ,have never been more important.distancing,wearing of a mask ,making sure that it's over your nose and mouth with clean hands.making sure you avoid crowded spaces.have be in rooms where there is good ventilation.and when it's your turn,get vaccinated.
