Nucleic acid test swabs are disposable and generally safe. Nucleic acid test swabs are used to collect tissues from the human throat or nasopharynx for nucleic acid testing of the New Coronavirus. To avoid transmission by contact, the swabs are disposable and are used individually, so there is no sharing problem, and therefore they are generally safe. In addition to this, when collecting samples from each individual, healthcare workers will disinfect their hands to minimize the possibility of transmission. During nucleic acid testing, care needs to be taken to maintain a one-meter separation from others and to wear a good mask and wash your hands frequently when you are not testing yourself. When the test result is abnormal, it should be reported in accordance with the principle of epidemic prevention, and immediately initiate isolation and wait for professional arrangement.
