Background: Coronavirus disease (COVID-19) has become pandemic. The knowledge, attitudes, and practices (KAP) of the public play a major role in the prevention and control of infectious diseases. The objective of the present study was to evaluate the KAP of the Chinese public and to assess potential influencing factors related to practices.Methods: A cross-sectional online survey was conducted in China in February 2020 via a self-designed questionnaire comprising 33 questions assessing knowledge, attitudes, and practices.Results: For the 2,136 respondents from 30 provinces or municipalities in China, the accurate response rate for the knowledge section was 72.7–99.5%, and the average was 91.2%. In the attitude section, the percentage of positive attitudes (“strongly agree” and “agree”) ranged from 94.7–99.7%, and the average value was 98.0%. The good practices (“always” and “often”) results ranged from 76.1–99.5%, and the average value was 96.8%. The independent samples t-test revealed that gender and ethnic differences had no effect on knowledge, attitude or behaviour (P > 0.05). However, knowledge was associated with age (t = 4.842, p < 0.001), marital status (t=-5.323, p < 0.001), education level (t = 8.441, p < 0.001), occupation (t=-10.858, p < 0.001), and place of residence (t = 7.929, p < 0.001). Similarly, attitude was associated with marital status (t=-2.383, p = 0.017), education level (t = 2.106, p = 0.035), occupation (t=-4.834, p < 0.001), and place of residence (t = 4.242, p < 0.001). The results of multiple linear regression analysis showed that the factors influencing practices were knowledge (t=-3.281, p = 0.001), attitude (t = 18.756, p < 0.001), occupation (t=-3.860, p < 0.001), education level (t = 3.136, p = 0.002), and place of residence (t = 3.257, p = 0.001).Conclusions: The Chinese public exhibited a good level of knowledge of COVID-19, a positive attitude, and high adherence to good practices. COVID-19-related knowledge, attitudes and practices were affected by age, marital status, education level, occupation, and place of residence to varying degrees. In addition, practices were affected by knowledge and attitudes toward COVID-19.
