Concerned about the global new crown pneumonia epidemic, "Delta" is a key word that cannot be avoided
Guangdong has "zero new additions" for two consecutive days.
Guangdong has "zero new additions" for two consecutive days.
Feng Zijian, a researcher at the Chinese Center for Disease Control and Prevention: There have been no new cases of the "5.
Guangzhou "5.
Shenzhen "5.

How to understand the source of infection in Shenzhen and Guangzhou cases, which belong to the delta variant strains of different sequences? On the CA868 flight entering Shenzhen from South Africa, more than 30 infected people were infected with different viruses in different places.
How to treat the shortest 14-second transmission case in Guangzhou?
How to treat the shortest 14-second transmission case in Guangzhou? 14 seconds is not an indicator of how fast the disease spreads
What are the characteristics of delta mutant virus in terms of pathogenicity?
What are the characteristics of delta mutant virus in terms of pathogenicity? "Delta" seems to be more pathogenic in the spread of "Delta" in India and in the UK, which means that the proportion of symptomatic people among infected people has increased
Will the clinical symptoms of infection with the delta mutant strain be different?
Will the clinical symptoms of infection with the delta mutant strain be different? First of all, in clinical manifestations, there is no significant difference between the clinical manifestations of the "Delta" virus and the clinical symptoms caused by previous strains.
How effective is my country's vaccine against delta mutant strains?
How effective is my country's vaccine against delta mutant strains? The existing vaccines in China still have considerable effectiveness against this virus, but the protective effect has also declined
Will the delta mutant strain replace the previous epidemic strain of the new coronavirus and become the main epidemic strain in the world?
Will the delta mutant strain replace the previous epidemic strain of the new coronavirus and become the main epidemic strain in the world? Very likely
Why does the new coronavirus mutate?
Why does the new coronavirus mutate? This is a characteristic of the virus itself
How can we "get one foot high" in response to the delta mutant strain?
How can we "get one foot high" in response to the delta mutant strain? Stricter measures are implemented
Speed up vaccination
.
Another very important method is that we must speed up the vaccination and quickly promote the wider coverage of the vaccine.
This will also suppress the spread of this virus and effectively curb the occurrence of this virus mutation
.
In response to mutant strains, the development of vaccines has never stopped
.
In response to mutant strains, the development of vaccines has never stopped
.
The World Health Organization, as well as our national vaccine research and development companies and research institutions, are promoting the development of vaccines against variant strains of the new coronavirus.
There are two main routes:
Production of second-generation vaccines
.
The so-called second-generation vaccine is the hope that a vaccine can be produced that can deal with various mutant strains, so that there is no need to worry about the escape of virus immunity, but this research route is more complicated, and the time for successful development is also hugely uncertain.
.
Production of second-generation vaccines
.
Produce improved vaccines
.
The main thing is to add or use new mutant virus strains in the vaccine, and its genetic sequence to replace the old vaccine, which is the existing vaccine
.
After these vaccines are developed, they can be continuously vaccinated with existing vaccines, or they can be boosted with new and improved vaccines and vaccines that have changed strains, including re-vaccinations
.
Produce improved vaccines
.
We must not let go of our fatigue when we "face-to-face" with the "Delta" mutant strain
.
We must not let go of our fatigue when we "face-to-face" with the "Delta" mutant strain
.
Since March and April of last year, China has emphasized normalization of epidemic prevention and control, and has insisted on implementing the prevention and control strategy of "prevention from foreign sources and internal defense against rebounds.
" Such strict precautions have lasted for more than a year
.
Over time, we may experience some slack, exhaustion, and fatigue in prevention and control work.
This is what we have to overcome.
We must also maintain a high level of alertness and maintain a very good working condition to prevent the spread of the epidemic.
And spread
