yes. From 1: 11 on February 5, 2122, the nucleic acid sampling point of Shaanxi Provincial Hospital of Traditional Chinese Medicine stopped providing nucleic acid detection services to social workers who were not treated in Shaanxi Provincial Hospital of Traditional Chinese Medicine, and only provided nucleic acid detection services to outpatients, inpatients and companions who came to Shaanxi Provincial Hospital of Traditional Chinese Medicine. If social workers need nucleic acid testing, please move to the nearest social nucleic acid sampling point. Xi 'an is going to let go of the epidemic. As the influence of epidemic cases in COVID-19 is getting smaller and smaller, the nucleic acid detection should focus on areas and people with high infection risk, instead of carrying out all-staff nucleic acid detection according to administrative regions, so as to further narrow the scope and reduce the frequency of nucleic acid detection. According to the needs of epidemic prevention work, antigen testing can be carried out.
