Alert! Novel coronavirus mutates again, expert warns urgently

In a week of warnings about the mutated strain, the Centers for Disease Control and Prevention (CDC) said cases of the novel coronavirus strain had surged, with the possibility of another expansion in March.

Yu Chuanhua, a professor of epidemiology and health statistics at Wuhan University, told reporters:

“It’s normal for the virus to mutate, but it could have an impact on vaccine development.
Vaccine development based on the original strain may not be able to effectively cover the impact of the new strain, and the genetic variation of the new strain should be fully taken into account in vaccine development.”

Many countries released new strains

The possibility of infection spreading again may arise in March

On February 18, Japan’s National Institute of Infectious Diseases (NII) announced that a novel mutant novel coronavirus was found in Japan. Its infectiousness is not stronger, but it may weaken the effect of antibodies. This new strain has obvious characteristics of “immune avoidance”.

The new strain, named E484K by Japan’s National Institute of Infectious Diseases, is different from those found so far in Britain, as well as in South Africa and Brazil.
Japan’s National Institute of Infectious Diseases does not yet know the source of the new strain.

On February 18th

Japan has 1,537 new infections

Thirteen of them were infected with the new strain

New cases of the novel coronavirus strain have surged, the Centers for Disease Control and Prevention (CDC) said Tuesday, with the possibility of another expansion of infection in March.
“The novel coronavirus strain found in the United Kingdom appears to be more infectious than previous strains,” CDC Director John Wollensky warned Wednesday.

As of February 16, there were 1,299 confirmed cases of the new strain in the United States, according to the Centers for Disease Control.
This comes only about two months after the first case of the new strain was confirmed in Colorado on December 29, 2020.
The vast majority (1,277 cases) were infected by the B.1.1.7 variant found in the United Kingdom.
The variant has been found in 41 US states and Washington DC.

In addition to

Germany is also facing a new strain

On February 18, Germany’s health ministry said in a statement that DNA sequence analysis of more than 23,000 new infections showed that more than 20 percent of those infected were infected with the new strain found in Britain.
Germany’s health ministry expects that after two weeks, 80 percent of new infections will be from the new strain.

Experts warn that the Covid-19 outbreak may take longer to prepare

Yu Chuanhua, a professor of epidemiology and health statistics at Wuhan University, told reporters:

“Covid-19 is a single-stranded RNA virus, which is more mutable than normal DNA viruses.
Novel coronavirus infection after the symptom itself is more complex, with the person’s age, physical condition, amalgamation of various factors such as basic diseases.
The current strain of novel coronavirus appears to be more infectious than the strain circulating in the early stages of the pandemic, which is actually the result of the constant mutating of the virus in nature.”

“The new strains mentioned in reports in some countries may make people vulnerable to a second infection after a first infection.”

Yu Chuanhua told reporters

Under normal circumstances

After the patient’s first infection

They produce antibodies

Homoviruses are less likely to be reinfected

But the discovery of this novel coronavirus strain

There may be a chance of secondary infection in patients recovering from the new crown

Could cause the virus to spread again

China strictly guard against the import of this new strain from outside the country

Take on particular importance

Yu Chuanhua said it could have an impact on vaccine development.
If only the original virus strain is used for vaccine development, it may not be able to effectively cover the influence of the new virus strain. In the research and development of vaccine, the genetic variation of the new virus strain should be fully taken into account, so as to avoid the failure of the final vaccine to cover the new mutant virus strain.

Therefore, the COVID-19 epidemic needs to be prepared for a longer time, such as timely detection of virus variants, timely carrying out related research and timely improvement of response measures.
Yu Chuanhua reminded that the current COVID-19 epidemic situation abroad is still in a large-scale epidemic state, must not be paralyzed.
In general, any confirmed cases or asymptomatic infections found among people entering the country are unlikely to enter the general community, and the public should not panic.
However, people should still wear masks, wash their hands frequently, ventilate frequently, gather less, consciously do personal protection, and form good hygiene habits.
