How to check the big data spread by Shaanxi health code?

Nucleic acid detection is a method to quickly check whether COVID-19 is infected by throat swab. Nucleic acid detection first needs to collect the patient's pharyngeal secretion with a throat swab, and detect whether COVID-19 is infected by real-time fluorescence RT-PCR.

If the test results are positive, it means that COVID-19 is infected. COVID-19 has strong communication skills, which can be spread through droplets and close contact. Therefore, during the epidemic period, relevant measures should be taken to prevent COVID-19, such as wearing a mask when going out, keeping a safe distance from others and washing hands frequently.
