In the last month or so, India has seen a surge in new coronavirus infections. In the Indian wave of the epidemic, experts have discovered a "new generation" of mutant viruses different from the British, which some call "triple mutation" strains.
So what are the new features of this "triple mutation" strain in India? What is more frightening about this mutant strain? Will the mutated strain be more transmissible than ordinary viruses? Recently, Professor Liang Zong'an, Director of the Department of Respiratory and Critical Care Medicine at West China Hospital of Sichuan University, has explained this.
First, let's get to know the "real face" of the mutated new coronavirus that appeared in India.
A mutated neo-coronavirus has emerged in India and has spread to more than 40 countries and regions. What are the new features of this mutated virus compared to the earlier mutated viruses found in the UK, South Africa and Brazil?
This mutant virus that has emerged in India has a three-point mutation, and due to this change, this mutant virus is more infectious, although the final word is not yet available. As to whether the disease will be heavier after infection with this mutated new coronavirus, Liang Zong'an pointed out that from the existing epidemiological investigation, this issue is also inconclusive, the reason is that epidemiological studies must cover the whole range, tracking and observation within a certain period of time, and very often we can not easily do this.
Secondly, the new rapid nucleic acid test is still the "gold standard".
So, for mutated viruses, is the Nucleic Acid Rapid Test still valid? Liang Zong'an believes that, strictly speaking, the new crown nucleic acid loss test is still the "gold standard" for the detection of new crown, is more reliable and certain, will not change the test results because of the emergence of mutated viruses. At present, the domestic whole staff new crown nucleic acid rapid test screening mostly used to new crown nucleic acid rapid test, new crown nucleic acid rapid test compared to conventional nucleic acid test, in the detection speed has been greatly improved, can meet the new situation of primary medical institutions new crown nucleic acid rapid test demand.
The whole process of New Crown Nucleic Acid Rapid Test is strictly debugging and optimizing the testing procedure in the development stage for the matching between reagents and reagents, reagents and instruments. At the same time, whether it is a large-scale sample screening or a small batch of rapid testing, New Crown's nucleic acid testing system can set up sufficient negative quality control for each batch of sample testing as required to ensure that the test results are true and valid.
