目的：研究市民对综合症的认识和看法，以及采取各项预防措施的程度。设计：横断面调查。研究对象：综合症爆发高峰期的香港一般人口（2003年3月29日至4月6日）。对象：1115名华裔成年人。主要结果：40%的人不认为污染物是可能的传播方式，而55.1%的人认为感染可以通过空气传播。大部分受访者（30.1%）相信他们极有可能或有一定机会感染综合症，而只有四分之一的受访者相信，以调查时的实际个案死亡率2.8%及现时最佳估计的15%至20%为基准，他们若感染综合症，极有可能存活下来。大多数国家普遍采取预防措施，防止飞沫在人与人之间传播，但预防通过污染物传播的措施并不多见。具有较高风险认知和中等焦虑水平的受访者最有可能采取全面的预防措施来预防感染，老年人，女性，受教育程度较高的人以及有积极接触史和SARS样症状的人也是如此。研究结果显示，推广个人健康防护措施，以阻断SARS病毒在社区的持续传播，考虑到一般公众对风险和焦虑程度的背景看法。关于预防措施的持续公共教育应针对目前预防措施接受率低的已确定群体。
Objective: To examine the public's knowledge and perception of SARS and the extent to which various precautionary measures have been adopted.Design: Cross sectional survey.Setting: General population of Hong Kong at the height of the SARS outbreak ( 29 March to 6 April 2003).Participants: 1115 ethnic Chinese adults.Main results: Forty per cent did not recognise fomites as a possible mode of transmission whereas 55.1% believed that the infection could be transmitted airborne. A large proportion (30.1%) believed they were very or somewhat likely to contract SARS while only one quarter believed they were very likely to survive if they contracted the disease, benchmarked against an actual case fatality ratio of 2.8% at the time of the survey and 15%-20% according to current best estimates. Precautionary measures directed against person to person droplet spread were generally adopted by most while the prevention of transmission through fomites was not practised as frequently. Respondents with higher risk perceptions and a moderate level of anxiety were most likely to take comprehensive precautionary measures against the infection, as were older, female, more educated people as well as those with a positive contact history and SARS-like symptoms.Conclusions: The findings demonstrate that the promotion of protective personal health practices to interrupt the self sustaining transmission of the SARS virus in the community must take into account background perceptions of risk and anxiety levels of the public at large. Continuing public education about preventive measures should be targeted at the identified groups with low current uptake of precautions.
