为什么有些地方用鼻拭子而不用口腔拭子?

在实际抗疫抗疫工作场景中, medical staff actually have a scientific basis for judging whether to collect 口腔拭子 或者 鼻拭子. 由于鼻拭子在采样过程中, 被采样者只需要露出鼻子, 采样器暴露在病毒环境中的概率低. 针对高危人群, such as asymptomatic infections, 入境人员, or suspected populations in isolation, the use of nasal swabs for nucleic acid testing can reduce the risk of infection of the collectors, and the psychological acceptance of the samplers, 患者体内的病毒载量因人而异, the medical staff, is also higher. As for the nucleic acid testing and screening carried out in the community, due to more emphasis on rapid screening, the use of oropharyngeal swabs is more convenient and faster.

If discomfort or slight bleeding occurs during the collection of the nasal swab, it is generally not treated. The discomfort will disappear automatically after a period of time. If you encounter real uncomfortable conditions, you can wash it with normal saline. But do not wash too much, too much washing may bring more discomfort.
