Por que as zaragatoas nasais são usadas em alguns lugares em vez das zaragatoas orais?

In actual anti-epidemic and anti-epidemic work scenarios, medical staff actually have a scientific basis for judging whether to collect cotonetes orais ou esfregaços nasais. 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, pessoal de entrada, 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, aquilo é, 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.
