Since the nasal swab is in the sampling process, the sampled person only needs to expose his nose, and the probability of the sampler being exposed to the virus environment is low. For high-risk populations, such as asymptomatic infections, พนักงานรายการ, 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, นั่นคือ, 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.
