During the peak of the outbreak of severe acute respiratory syndrome (SARS), we conducted a survey in Beijing on 18 April 2003 to determine the economic impact of SARS, in particular its effects on several service sectors in China. The survey indicated that SARS had significant negative impacts on China's economy. The tourism sector was hit the hardest. We estimated that by the end of 2003, China's tourism revenue from foreigners would decrease by about 50-60 percent (amounting to about US$10.8 billion) compared with the tourism revenue in 2002 and revenue from domestic tourists would decrease by around 10 percent (amounting to about US$6.0 billion). Thus, we predicted that the total loss to China's tourism industry would be around US$16.8 billion by the end of 2003. We also concluded that SARS would cause, through a multiplier effect, a total loss of US$25.3 billion to China's economy and that the growth rate of China's GDP in 2003 would be 1-2 percentage points lower than it would have been if the SARS outbreak had not occurred.

Background Information disclosure is a top priority for official responses to the COVID-19 pandemic. The timely and standardized information published by authorities as a response to the crisis can better inform the public and enable better preparations for the pandemic; however, there is limited evidence of any systematic analyses of the disclosed epidemic information. This in turn has important implications for risk communication. Objective This study aimed to describe and compare the officially released content regarding local epidemic situations as well as analyze the characteristics of information disclosure through local communication in major cities in China. Methods The 31 capital cities in mainland China were included in this city-level observational study. Data were retrieved from local municipalities and health commission websites as of March 18, 2020. A checklist was employed as a rapid qualitative assessment tool to analyze the information disclosure performance of each city. Descriptive analyses and data visualizations were produced to present and compare the comparative performances of the cities. Results In total, 29 of 31 cities (93.5%) established specific COVID-19 webpages to disclose information. Among them, 12 of the city webpages were added to their corresponding municipal websites. A majority of the cities (21/31, 67.7%) published their first cases of infection in a timely manner on the actual day of confirmation. Regarding the information disclosures highlighted on the websites, news updates from local media or press briefings were the most prevalent (28/29, 96.6%), followed by epidemic surveillance (25/29, 86.2%), and advice for the public (25/29, 86.2%). Clarifications of misinformation and frequently asked questions were largely overlooked as only 2 cities provided this valuable information. The median daily update frequency of epidemic surveillance summaries was 1.2 times per day (IQR 1.0-1.3 times), and the majority of these summaries (18/25, 72.0%) also provided detailed information regarding confirmed cases. The reporting of key indicators in the epidemic surveillance summaries, as well as critical facts included in the confirmed case reports, varied substantially between cities. In general, the best performance in terms of timely reporting and the transparency of information disclosures were observed in the municipalities directly administered by the central government compared to the other cities. Conclusions Timely and effective efforts to disclose information related to the COVID-19 epidemic have been made in major cities in China. Continued improvements to local authority reporting will contribute to more effective public communication and efficient public health research responses. The development of protocols and the standardization of epidemic message templates—as well as the use of uniform operating procedures to provide regular information updates—should be prioritized to ensure a coordinated national response.

BACKGROUND Information disclosure is a top priority for official responses to the 2019 coronavirus pandemic (COVID-19). The information published by the authorities as a response to the crisis has been a cause of great concern to the public; however, there is limited evidence of any systematic analyses of the disclosed epidemic information. This in turn has important implications for risk communication. OBJECTIVE This study aimed to describe and compare the officially released content regarding the local epidemic situations and analyze the characteristics of information disclosure through local transmission for both the individual and total population levels in major cities of China. METHODS The 31 capital cities in mainland China were enrolled in a city-level observational study. Data were retrieved from local municipalities and health commission websites as of March 18, 2020. A checklist was employed as a rapid qualitative assessment tool to analyze the information disclosure performance of each city. Descriptive analyses and data visualizations were produced to present and compare the comparative performances of the cities.

Clarifications of misinformation and frequently asked questions were largely overlooked as only 2 cities provided this valuable information. The median daily update frequency of epidemic surveillance summaries was 1.2 times per day (interquartile range 1.0 to 1.3 times), and the majority of these summaries (18 of 25, 72.0%) also provided detailed information of confirmed cases. The reporting of key indicators in the epidemic surveillance summaries, as well as critical facts included in the confirmed case reports, varied substantially between cities.
