為什麼有些地方用鼻拭子而不用口腔拭子?

在實際抗疫抗疫工作場景中, medical staff actually have a scientific basis for judging whether to collect 口腔拭子 或者 鼻拭子. 由於鼻拭子在採樣過程中, 被採樣者只需要露出鼻子, 採樣器暴露在病毒環境中的概率低. 針對高危人群, such as asymptomatic infections, 入境人員, 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, 那是, 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.
