If the sampling tube is in a tube that has not yet been used, then contact with the liquid in the nucleic acid sampling tube is generally of little consequence and will not poison or infect the virus, so there is no need to be overly concerned. If the sampling tube has been in contact with or put into the specimen, there is a risk of infecting the new crown and contaminating the environment, and the process should be followed to isolate, disinfect and report. The liquid in the nucleic acid sampling tube is a reagent used to preserve the virus and is generally of no consequence until virus sampling has been carried out, as the liquid does not contain the virus sample. Exposure to the liquid in nucleic acid sampling tubes does not generally result in infection with the new coronavirus or toxicity. Although the components are neither toxic nor corrosive and will not cause any effect on the body, it is still recommended that extra care should be taken to rinse the area touched with hand sanitizer or disinfectant water, etc., in case of contact with the liquid in the nucleic acid sampling tubes. If the sampling tube has touched or been placed in a specimen, there is a risk of infection with a new crown and contamination of the environment, which should be quarantined, disinfected and reported in accordance with the procedures. Although the liquid in the nucleic acid sampling tube is not a toxic liquid, it is still recommended to be careful and wear protective gears such as gloves, goggles, etc. when performing the corresponding operations.
