Since March, the epidemic situation in China has shown multiple epidemic situations, followed by the invasion of Omicron strain, which makes the epidemic situation in China complex and changeable. Since the outbreak in Shanghai in March, up to now, China has accumulated more than 600,000 cases of confirmed positive infections by rapid testing of native new crown nucleic acid.

It is reported that the epidemic is Omicron BA.2, which has a transmission strength of 9.5 R0 value, meaning that one person can transmit 10 people. (R0 is the index of virus transmission.) The risk of potential transmission is also always present.

In this context, the function of the new crown nucleic acid rapid test is changing. In the past it was mainly used for risk screening in outbreak sites, but now it has become an important part of outbreak risk prevention. The normalization of the Nucleic Acid Rapid Test is an important way to "detect, contain and cut off" the spread of the virus. A negative Nucleic Acid Rapid Test result is like a new "Code Green" and has become a standard part of life in the normalization of epidemics. However, there are multiple challenges under the normalization of the Nucleic Acid Rapid Test.

1. Economic aspects.

From the point of view of health economics, many public health experts have said that it is a more cost-effective strategy in the medium and long term to use the normalized Nucleic Acid Rapid Test for early detection and early action than the economic loss caused by large-scale and prolonged containment and control. However, the current situation in the new normal, the "account" about the expenditure of the new crown nucleic acid rapid test has become a point of concern.

It is reported that the current health insurance is still not for the normalization of the new crown nucleic acid rapid test to buy, large-scale new crown nucleic acid rapid test mostly rely on local financial maintenance. This has also caused some pressure on certain economically underdeveloped areas. But at present, the new crown nucleic acid rapid test collection is also carried out so that the new crown nucleic acid rapid test supplies and other prices have dropped to a great extent. Multiple mixed picking this low-cost new crown nucleic acid rapid test has also become an important way in the new crown nucleic acid rapid test.

2, the system and system of normalized new crown nucleic acid rapid test. The normalization of the new crown nucleic acid rapid test must have a series of complete management system.

New crown nucleic acid rapid test frequency should be determined by the time and situation. The essence of the normalization of the new crown nucleic acid rapid test is to form a system and system, around the development of specific objectives, requirements and standards, and then implemented to the choice of location, facility construction, personnel allocation, etc., so that the "inspection" of the infected system is built up. You can't check without restraint, and you can't not check.

3, the new crown nucleic acid rapid test accuracy. Long-term rapid test volume of millions of new coronary nucleic acid testing, sampling, testing personnel energy and operational standards will bring great challenges. Qualified sampling and testing personnel recruitment and training has become a great difficulty. Currently, the lack of standardization of product sampling, lack of control of logistics and transportation quality, and lack of supervision of quality management of samples to be tested also create some possible risks, such as false negatives, false positives, sample leakage, and biological contamination.

To ensure the accuracy of the new crown nucleic acid rapid test is the basic requirement of the normalized nucleic acid test.

4, under the normalized new crown nucleic acid rapid test, the new crown nucleic acid rapid test still needs to be online. Although the normalized new crown nucleic acid rapid test can be to a certain extent the risk of hidden transmission of the epidemic is reduced. However, rapid neo-crown nucleic acid testing is still an important tool in customs, airports, and fever clinics for prevention and control.

Under the standing NIC rapid test, routine screening can be achieved for low-risk populations, while high-risk populations still require rapid disposal tools. The Nucleic Acid Rapid Test, which uses highly efficient amplification reagents and a portable amplification instrument, is able to intercept the source of transmission more quickly. Therefore, under normalized testing, the new crown rapid test still needs to be equipped.

The normalized prevention and control of the new crown epidemic still needs to keep up with the times and rely on the power of science and technology.
