Résumé

Background Since December 2019, pneumonia associated with the 2019 novel coronavirus (2019-nCoV) has emerged in Wuhan, China. The exponential increase of the confirmed number of cases of 2019n-CoV is of great concern to the global community. The fears and panic among residents in the epicenters have prompted diverse responses, which are understudied. During such a crisis, community trust and support for the government and health authorities are important to contain the outbreak. We aimed to investigate the influence of institutional trust on public responses to the 2019-nCoV outbreak. Methods An anonymous Internet-based, cross-sectional survey was administered on January 29, 2020. The study population comprised all residents currently residing or working in the province of Hubei, where Wuhan is the capital city. The level of trust in information provision and preventive instructions, individual preventive behaviors and treatment-seeking behaviors were queried. Findings The majority of the participants expressed a great extent of trust in the information and preventive instructions provided by the central government than by the local government. A high uptake of 2019-nCoV preventive measures was found, particularly among people who had been placed under quarantine. Being under quarantine (adjusted odds ratio [OR] = 2.35, 95% confidence interval [CI] 1.80 to 3.08) and having a high institutional trust score (OR = 2.23, 95% CI 1.96 to 2.53) were both strong and significant determinants of higher preventive behavior scores. The majority of study participants (85.7%, n = 3,640) reported that they would seek hospital treatment if they suspected themselves to have been infected with 2019 n-CoV. Few of the participants from Wuhan (16.6%, n = 475) and those participants who were under quarantine (13.8%, n = 550) expressed an unwillingness to seek hospital treatment. Similarly, being under quarantine (OR = 2.36, 95% CI 1.80 to 3.09) and having a high institutional trust score (OR = 2.20, 95% CI 1.96 to 2.49) were two strong significant determinants of hospital treatment-seeking. Interpretation The results of this study suggest that institutional trust is an important factor influencing adequate preventive behavior and seeking formal medical care during an outbreak. In view of the 2019-nCoV being highly pathogenic and extremely contagious, our findings also underscore the importance of public health intervention to reach individuals with poor adherence to preventive measures and who are reluctant to seek treatment at formal health services.

Résumé

The 2019-nCoV outbreak occurred near the Chinese Spring Festival transport period in Wuhan. As an important transportation center, the migration of Wuhan accelerated the spread of 2019-nCoV across mainland China. Based on the cumulative Baidu migration index (CBMI), we first analyzed the proportion of Wuhan's migrant population to other cities. Our results confirm that there is a significant correlation between the export population of Wuhan and reported cases in various regions. We subsequently found that the mortality rate in Hubei Province was much higher than that in other regions of mainland China, while the investigation of potential cases in Wuhan was far behind other provinces in Mainland China, which indicates the effectiveness of early isolation.
