What benefits does anal swab nucleic acid test have for the public?

We have all gained a lot of new knowledge since the outbreak of novel coronavirus. For example, even if two people are not in direct contact, it may be contagious. Later, with the efforts of many experts, we know that there is a detection reagent that can detect whether you are infected by dipping a certain amount of saliva in your mouth. And then we found out that this virus is really cunning. It may lurk for many days, and even if it is detected by throat swab several times, it may be cleverly avoided. Of course, scientists are also working hard, and recently they have brought good news to everyone. In addition to swallowing the formula, scientists have invented a reagent-anal swab through continuous efforts.

What is an anal swab? In fact, I believe many friends have already known each other by name. The so-called pharynx prescription is to dip some saliva in the pharynx to detect whether there is a virus infection. Where's the anal swab It must have passed the anal test. So although many friends will be very worried, this detection method is really embarrassing and awkward. Of course, there are still many netizens teasing on the Internet, and the testing station should be placed next to the public toilet.

What are the advantages of anal swab test compared with throat test? In fact, in the above, we also mentioned the convenience of laryngeal test more or less, but there are still some defects after all. After all, novel coronavirus has a certain incubation period in the body. During the latent period, he probably escaped the detection of throat swab by luck. Anal swab test is based on detoxification from feces, which is a common phenomenon in the process of coronavirus infection. That is to say, generally speaking, the duration of positive stool test may be longer than that of pharynx, which is more conducive to our screening accuracy of infected patients earlier and will also improve relatively.

Is it possible to conduct a wide range of tests on anal swabs? Anal swab requires much higher privacy than throat swab, and at present, this kind of anal swab is difficult for many friends to accept, and the detection will be more complicated, which is not suitable for large-scale screening and detection. Of course, in some epidemic areas and high-risk areas, if the number of cases increases, anal swab testing will also provide a better choice. Especially when there are many asymptomatic infected people in the population, anal swab detection can play an auxiliary role in screening. However, at present, this detection method can not be widely promoted for comprehensive detection.
