Do you know anything about anal swabs?
The study found that these patients were positive not only in the Nasopharyngeal and oropharyngeal swabs but also in the anal swabs, which proved the possibility of COVID-19 spreading through the fecal mouth.
The study also found that anal swabs were more accurate than nasal and oropharyngeal swabs.
After entering the body through the nasal cavity and mouth, COVID-19 does not stay at the entrance. The purpose of the body is to penetrate the body. Therefore, those infected with asymptomatic infection and mild symptoms were infected with COVID-19 3~5 days later. The virus in the pharynx could not be detected by nucleic acid (1~2 could not be detected after ordinary people), but the duration of nucleic acid detection in the alimentary canal was significantly longer. The longest case of anal swab lasted for 51 days.
Anal swab & test tubes containing preservation solution
The increase of anal swabs is helpful to improve the detection rate of COVID-19 infected people.
In addition, anal swabs are less painful than nasal and oropharyngeal swabs for healthy groups. Some people even say that “the process is painless”, but they are forbidden to be used for those who have anal erosion, ulcer, abscess and have just completed anorectal surgery.
Compared with the unspeakable sour feeling of nose and oropharyngeal swabs, anal swabs are really comfortable! Because nasal and oropharyngeal swabs are deep after all.
