The World Health Organization stated that
Its member states reported on Saturday
More than 212,000 new cases of COVID-19,
This is the highest single-day total since the beginning of the pandemic .
The UN health agency said,
More than half of newly diagnosed infections
Reported in Brazil and the United States,
These two countries are also in the world
COVID-19 has the highest number of deaths.
U.S. Saturday nationwide
Reported more than 50,000 newly diagnosed cases,
And Brazil recorded
Nearly 38,000 new infections and 1,091 deaths.
India also set a record high in a single day,
22,771 newly diagnosed cases,
A total of more than 648,000 cases,
Infection cases in South Africa and Russia have also surged.
Total cases in Latin America and the Caribbean
There are more than 2.7 million cases of infection.
Even in certain parts of the world
In an effort to reopen the plan carefully,
This increase is still happening.
Although Canada, the United Kingdom and parts of Europe,
The number of new cases has been decreasing,
However, in some states of the United States, it is not reduced but increased.
The United States recently reported that
The daily number of COVID-19 cases hits a record high,
40 of its 50 states
The infection rate is on the rise.
Florida and Texas have
Become the latest hot spot in the United States,
A total of 20,000 new infections have been reported.
To make matters worse,
The latest CNN report said,
The new corona virus has mutated.
A global study found that
Strong evidence shows that
A new virus strain has spread from Europe to the United States.
An international research team reported on Thursday that
This new mutation
Makes this virus more likely to infect people,
But it does not seem to increase its lethality.
La Jolla Immunology Institute
With the Coronavirus Immunotherapy Association
Erica Orman Safir
(Erica Ollmann Saphire) said:
“Now, this new strain
It is the main form of infection of the new crown. ”
The research was published in the journal “Cell”,
The shared information about the genetic sequence shows that
Some mutant forms of the virus
The old version of the virus is being replaced.
The research team not only checked more gene sequences,
And also carried out involving human and animal cells
Experiments in laboratory petri dishes,
These experiments show the mutated version
More common and more infectious than other versions.
Mutation affects spike protein-
This is the structure that the virus uses to infect human cells.
Researchers are checking
Does this affect the effectiveness of the old vaccine.
The vaccine currently being tested
Mainly for spike protein,
But they are based on older virus strains.
Researchers call this new mutation G614,
They proved that it almost completely replaced
D614, the first version popular in Europe and the United States.
No effect on patient survival
Los Alamos National Laboratory
Theoretical biologist Bette Korber
And colleagues wrote in the report:
“Our global tracking data shows that
The G614 variant propagates faster than D614. ”
“We think this means,
The virus may be more contagious.
We did not find G614
Evidence of impact on disease severity. ”
University of Warwick
(University of Warwick)
(Lawrence Young) said,
This may be good news.
He said in a statement:
“Current research shows that
Although the G614 variant may be more contagious,
But it is not more pathogenic.
People hope that as the SARS-CoV-2 infection spreads,
The pathogenicity of the virus will be reduced. ”
The researchers say,
The new version seems to be in the upper respiratory tract-
The nose, sinuses and throat reproduce faster,
This can explain why
It is easier to spread through people.
But in the UK, 1,000 patients were hospitalized
The tests conducted showed that
Conditions of patients infected with new viruses
Nothing is worse than patients infected with the original virus.
Spokesperson for AIDS Vaccine Research and Development Laboratory
“All results show that
Form G is 3 to 9 times more infectious than Form D. ”
“We now have experimental evidence,
Partially supported Dr. White
What I saw when analyzing the global sequence-
Form G has adaptive advantages in terms of infectivity. ”
According to the beginning,
The G614 strain has only appeared 7 times.
But after March,
Amazing growth in the world.
To the present,
The strong virus overwhelms the weak virus,
I believe everyone knows what is “group immunity”.
The British Chief Scientific Adviser once said,
Infected tens of millions of British people with the new crown,
You can get group immunity.
According to CNN’s report on March 25,
A group of teenagers in Kentucky, USA
Held a “New Crown Pneumonia Party”,
Provoking and mocking the epidemic prevention methods of isolated people,
As a result, someone was diagnosed with the infection.
American young people feel that they are not easily infected,
But the US authorities cite data warnings,
Young adults between 20 and 54 years old,
After being infected with new coronary pneumonia,
Up to nearly 40% are hospitalized for treatment.
However, many young people are still partying,
Regardless of the risk of infection,
Let the epidemic worse.
Queen’s University of Canada already has a student union officer
Resigned for holding a new crown party.
Some experts say,
The reopening of European and American bars and restaurants,
Customers give up the rules of physical alienation after drinking,
It is also the culprit of the surge in cases.
It is most likely that humans have despised it.
And the recent COVID-19 virus diagnosis in Ontario,
Began to gradually decrease.
Ontario health officials reported that
112 new cases of coronavirus were confirmed,
Compared with 154 new infections reported on Monday,
There is a significant reduction.
Ontario also recorded two new COVID-19 deaths,
This is a slight increase from the zero deaths reported on Monday.
Since late March,
There are many daily records in Ontario
Deaths associated with new coronaviruses.
At peak times,
Dozens of people die every day in Ontario.
The total number of diseases confirmed by Ontario in the laboratory
Among them, 2691 died and 31 603 recovered.
In the past 24 hours,
Ontario has made more than
15000 COVID-19 tests.
Since the epidemic raged,
Ontario health officials have
Conducted more than 1.5 million tests.
More than 12,000 case tests are still under investigation.
Living bacteria remind everyone here,
Must pay attention to protection,
Often the danger comes when you take it lightly!
