    Snippet: The reasons lies behind this phenomenon may be due to several causes. One of the influencing factors is the sampling techniques. We found very high copies of NCP virus in the deep nasopharyngeal swab sample of the patient No. 18, whose first nasopharyngeal swab collected one day before by another physician was negative, which suggests that standard sampling strictly according to the protocol may increase the sensitivity of the specimens. Also, mo.....
    Document: The reasons lies behind this phenomenon may be due to several causes. One of the influencing factors is the sampling techniques. We found very high copies of NCP virus in the deep nasopharyngeal swab sample of the patient No. 18, whose first nasopharyngeal swab collected one day before by another physician was negative, which suggests that standard sampling strictly according to the protocol may increase the sensitivity of the specimens. Also, most of the cases published until now tends to use nasopharyngeal swab specimens for nucleic acid tests 19, 20 . Our study revealed that for some NCP patients with very mild pneumonia, their viral loads and mNGS sequences reads from the nasopharyngeal swab specimen could be as high as 2x10 6 copies/ul and 21,938,215 (patient No.8, seen in Supplement 1), the highest All rights reserved.
