Why is there always an epidemic in Xi 'an?

One reason is that Xi 'an first discovered the spread of Omicron BA.5 mutant in Chinese mainland.

This is the chief culprit of the new round of global epidemic, accounting for nearly 50% of the new cases in the world, and driving the epidemic in the United States, Canada, Singapore and other countries to rebound.

Compared with the mutant strain BA.2 at the beginning of the year, it has stronger transmission, faster transmission speed and stronger immune escape ability to the vaccine, which brings the risk of repeated infection.

Studies have shown that even if infected with other COVID-19 varieties or vaccinated, BA.5 can still break through the defense line and lead to reinfection.

Another reason is that the barriers of normalized nucleic acid detection have been abolished in many places, and the local epidemic has suddenly spread in many places, which cannot but attract people's attention.

At the end of June, many places announced the suspension or cancellation of national normalized nucleic acid testing, and some cities offered the means of "self-funded" normalized nucleic acid testing.

The reason for this undoubtedly lies in finance.

But on the one hand, it is a new variety with faster infection rate, on the other hand, it is an unbearable economic burden. How to prevent and control it accurately is obviously a difficult problem.

To prevent the epidemic, the economy should be stable and the development should be safe, and the comprehensive management ability of local governments should be tested.
