recently
The official website of the British government published a message
Three variants of the new coronavirus were reported.
The data shows that
637 cases of XE have been detected in the UK.
What is a recombinant variant of the coronavirus?
According to the website,
When an individual is infected with 2 or more variants of COVID-19 at the same time,
A recombinant variant is produced
（recombinant variant），
That is, the two strains are mixed to form a new version.
This situation is not uncommon,
During the COVID-19 pandemic
Several cases of RECOM variants have been identified.
What are the 3 recombinant variants in this report?
According to the UK Health Security Agency,
The 3 recombinant variants of the new coronavirus reported this time
They are XE, XD and XF.
XE is the Opichron BA.1 sum
Reorganization of O'Mikron's "sister" BA.2,
XD and XF are a reorganization of Delta and Amiqueron BA.1.
A cumulative total of 38 XF cases have been detected in the UK,
637 XE cases;
XD cases have been reported in the global database of 49 cases,
Most of them are in France.
Chief Medical Adviser to the UK Health Security Agency
Professor Hopkins noted in particular,
There is not yet sufficient evidence to mutate the strain XE
Conclusions are drawn about transmission, severity, or effectiveness of the vaccine.
Will the mutant strain XE become an epidemic strain in the future?
presently
The Olmiqueron strain has replaced the Delta strain
It has become the world's leading epidemic strain.
There are three subtypes of the Omikejong variant:
BA.1、BA.2和BA.3,
Among them, BA.2, which has the strongest communication ability, is the most popular.
And studies have shown that
New mutant strain XE infection rate
It is also 9.8% higher than the BA.2 mutant strain.
Scientists are paying close attention to the movement of the new coronavirus strain XE,
It is uncertain whether XE will become an epidemic strain.
March 30,
WHO Director-General Tedros Adhanom Ghebreyesus has said,
Available research shows that
The most likely scenario is
The new crown virus will continue to evolve,
But with the body's immunity
enhanced by vaccination or infection with the virus,
The severity of the disease caused by the new crown virus
Decreases over time.
But WHO has also warned all countries,
Never underestimate or underestimate the dangers of recombinant strains.
