Abstract:
Objective:To understand the basic characteristics of COVID-19 cases and the virus carrying status of different samples in Ma′anshan.Methods:Descriptive epidemiological method was used to describe the distribution of 2019-nCoV infections in Ma′anshan. Real-time fluorescence RT-PCR was used to detect 2019-nCoV nucleic acid in sputum and/or throat swabs. Data was analyzed by EXCEL and SPSS 20.0. P<0.05 was considered to be statistically significant by using χ2 test. Results:Until 14 March 2020, 38 confirmed cases and no death had been reported in Ma′anshan, there were also 11 asymptomatic infections. 2019-nCoV infection was first detected on January 23, and the last was on February 20. No new infections have been found for 23 consecutive days until March 14; 77.55%(38/49)of the infections were in He county. Among the 1 447 subjects, the positive rate was 4.50% (27/600) in females and 2.60% (22/847) in males (χ 2=3.886, P=0.049). The minimum age of the infections was 4 years and the maximum was 85. There was no significant difference between age groups ( χ2=10.675, P=0.058). Among the 49 infections, 20 of them (40.82%) were from Wuhan, 24 (48.98%) were locally infected, and 5 (10.20%) were imported from other places. For the first positive infections, the positive rate of sputum (100%, 36/36) was higher than the throat swab (77.78%, 28/36), and the difference was statistically significant (χ 2=6.125, P<0.05). Conclusions:In Ma′anshan, 2019-nCoV infections were concentrated in He county, sputum was beneficial to the detection of 2019-nCoV.
