Do you need a 48-hour nucleic acid test report to return to Xiangyang from Xihu District of Hangzhou during the Spring Festival?

Need. According to the epidemic prevention policy issued by Hubei CDC on June 23rd, 2022:

_ People who have lived in key areas in China and come to Hubei from high-risk areas in China will be kept under centralized medical observation until they leave the local area 14 days. After the expiration of centralized isolation medical observation, they were observed in home isolation medical observation 14 days.

_ In other parts of China, no matter whether there is an epidemic in the local area or not, check the negative certificate of nucleic acid test within 48 hours, carry out 1 nucleic acid test within 24 hours of residence, carry out community health monitoring 14 days, and carry out 1 nucleic acid test every 7 days.

Note: People who have lived in Binjiang District of Hangzhou, Zhuantang Street of Xihu District and Shushan Street of Xiaoshan District since June 5438+1October 65438+April, 2022 should take the initiative to declare their health to the local community and cooperate with various prevention and control measures of the local epidemic prevention and control headquarters.

What is the principle of extended reading * nucleic acid detection?

A: In nucleic acid detection, the collected samples will be mixed with the host's own cells, naturally carried bacteria or viruses, and even the cells of food residues.

Using PCR technology, the inspectors amplified the unique "password" of COVID-19 in the sample to a level that can be detected by instruments and equipment, so as to judge whether it is a positive infection. The whole process of grabbing viral genetic material is like fishing. The hook will recognize and grab it, so that the virus can hide.
