Objective: To investigate the positive rate for 2019-nCoV tests and co-infections in Wuhan district Methods: A total of 8 274 cases in Wuhan were enrolled in this cross-sectional study during January 20 to February 9 in 2020, and were tested for 2019-nCoV using fluorescence quantitative PCR Both respiratory tract samples (nasopharynx, oropharynx, sputum and alveolar lavage fluid) and non-respiratory tract samples (urine, feces, anal swabs, blood and conjunctival sac swabs) were collected If both orf1ab and N genes are positive, they are classified as nucleic acid test positive group;if both orf1ab and N genes are negative, they are classified as negative group;if single gene target is positive, they are classified as suspicious group Individuals were divided into male group and female group according to sex At the same time, 316 patients were tested for 13 respiratory pathogens by multiplex PCR Results: Among the 8 274 subjects, 2 745 (33 17%) were 2019-nCoV infected;5 277 (63 77%) subjects showed negative results in the 2019-nCoV nucleic acid test;and 252 cases (3 05%) was not definitive (inconclusive result) The age of cases with COVID-19 patients and inconclusive cases was significantly higher than that of cases without 2019-nCoV infection (56>40, t=27 569, P40, t=6 774, P<0 001) The positive rate of 13 respiratory pathogens multiple tests was significantly lower in 104 subjects who were positive for 2019-nCoV compared with those in subjects who were negative for 2019-nCoV test (5 77% vs 18 39%, χ2=24 105, P=0 003) Four types of respiratory tract samples and five types of non-respiratory tract sampleswere found to be positive for 2019-nCoV nucleic acid test Conclusion: The 2019-nCoV nucleic acid positive rate inmale is higher than infemale Co-infections should be pay close attention in COVID-19 patients 2019-nCoV nucleic acid can be detected in non-respiratory tract samples
