General Health Observation: The risk of infection with imported cold chain food is very low

The occurrence of sporadic cases is a normal phenomenon under the normalized prevention and control of the epidemic

After entering the winter, the global epidemic situation has become increasingly severe.
After November, the number of confirmed cases reported daily has often reached more than 600,000
.
In China, sporadic cases have recently been reported in Shanghai, Anhui, Tianjin, and Inner Mongolia
.
The emergence of these sporadic cases gives people a feeling that the virus is knocking on the country and is about to break in
.
Therefore, the world is facing the big exam, and China is also facing the big exam
.

In this regard, Wu Zunyou said that in the past 11 months, we have summarized a complete set of prevention and control measures, and can control the epidemic to the smallest extent in the first time
.
"Under the severe environment of the global epidemic, everyone should have an expectation that is more objective and realistic
.
" He said, "The occurrence of sporadic cases is a normal phenomenon under normalized prevention and control
.
We have experienced in the past 11 months.
It has also been successful
.
Especially like the National Day, there was a large flow of 600 to 700 million people, and there was no rebound of the epidemic
.
Now it is winter, and there will be a large flow of people during the Spring Festival.
As long as there are no infected people in the population, There will be no major epidemics

Large-scale nucleic acid testing is necessary and cost-effective

Judging from the response to the recent outbreaks, large-scale nucleic acid tests have been launched immediately after the outbreak
.
Some people have questions: Is this detection necessary? Does it meet the requirements of scientific protection? Is it cost-effective?

In this regard, Wu Zunyou said that with the development of technology, nucleic acid testing has become more and more mature, and it has become a standard for the prevention and control of the new crown pneumonia epidemic
.
After the emergence of an epidemic, large-scale nucleic acid testing is very necessary.
The sensitivity of nucleic acid testing is relatively high, and the scale of the epidemic can be determined soon
.
In this way, everyone took a "reassurance pill"
.

Large-scale nucleic acid detection methods are scientific
.
"Large-scale testing generally uses a 1:5 mixed test.
The samples of 5 people are put together for a test.
If it is negative, it will pass
.
If it is positive, then a tube-by-tube test will be carried out
.
Because the infection rate in the population is very low, For less than one ten thousandth, a 1:5 mixed inspection mode can be used to detect infected persons in a timely manner, and at the same time, large-scale and large-scale development can be carried out, which is cost-effective
.
" Wu Zunyou said
.

In addition, it is also beneficial for individuals
.
Wu Zunyou said that nucleic acid testing is still the most effective way to detect early cases in time
.
Through nucleic acid testing, the tester himself will benefit
.
If it is found to be positive, it can prevent the disease from changing from mild to severe, reduce harm to oneself, and prevent further spread
.
