关于新型冠状病毒肺炎患者出院后核酸检测 SARS CoV 2 RNA“复阳”原因及对策分析

At the end of December 2019, COVID-19 broke out in Wuhan, China and swept the whole world. Although the current domestic epidemic situation has been basically controlled, it was found that there were still some patients who have returned positive for the virus nucleic acid test after their recovery from the disease and being discharged from hospital, suggesting that the prevention and control of the pandemic is still a difficult challenge. There are two reasons for the recurrence of the positive result of nucleic acid test, one is the impact of the test itself, the other is the remnant of the virus. Most of the patients with recurrent positive result of nucleic acid test did not show aggravation of the condition, but they still need to be isolated after discharge. In order to reduce the probability of recurrent cases in discharged patients, more accurate diagnostic methods must be adopted, and individualized discharge standards can be developed according to different patients.
