在2019冠狀病毒病(COVID-19)的疫症大流行中，新型冠狀病毒(SARS-CoV-2) 的接觸環境於病毒傳播的過程中擔當著重要的角色。本研究的目的是為了評估人群暴露於香港不同接觸環境下所產生的新型冠狀病毒及其他呼吸道病毒傳播風險。研究成果將有助推動公共衞生政策發展，使疫症流行得以有效控制。
這是一項匿名的問卷調查。每住戶只限一位成員參與。參加者須年滿18歲及通常居住於香港。同意參加者需於登記參與研究時填答一份基線問卷，大約需時 10-15 分鐘，當中會詢問有關參加者的：(A) 社會人口特徵、(B) 新型冠狀病毒的感染史、接觸史及過往檢測經驗、(C) 過去一個月於不同接觸環境下（如家庭、工作場所/學校、日常活動、社交場合及醫療服務場地）的活動詳情及 (D) 2019冠狀病毒病疫苗接種史。於完成基線問卷接下來的 24 個月，參加者會被邀請每月填答一份大約需時5分鐘完成的簡便更新問卷。參加者需要根據過去一個月的情況更新 (B) 及 (C) 部分的資料。我們每月將通過電子郵件發送提示信息。根據疫症流行的水平及社交距離限制措施的變化，我們將有機會邀請參加者於額外的時間點填寫更新問卷。
每位完成基線問卷的參與者將可獲得價值港幣50元的超級市場現金券。於往後的每6個月中（第 1-6 個月、7-12 個月、13-18 個月，如此類推），完成至少 3 次更新問卷的參加者將可額外獲得超級市場現金券（每張價值港幣50元）。

Exposure setting has played a critical role in the pattern of virus transmission in the Coronavirus Diseases 2019 (COVID-19) pandemic. This study investigates the population risks of exposure to SARS-CoV-2 and other respiratory pathogens in different exposure settings in Hong Kong. The study results would be important for informing public health policy development to achieve effective control of epidemics.
This is an anonymous survey. Participation is limited to ONE person from each household, who is aged 18 or above and is normally living in Hong Kong. Consented participants will be invited to answer a baseline survey at study enrolment which can be completed in 10-15 minutes. In the baseline questionnaire, the following will be enquired: (A) socio-demographics, (B) history of SARS-CoV-2 infection, exposure, and testing, (C) activities in the past 1 month related to SARS-CoV-2 exposure in different settings (household, workplace/school, daily activity, social and healthcare setting) and (D) history of COVID-19 vaccination. In the ensuing 24 months after the completion of the baseline questionnaire, participants will be invited to complete monthly updates, which are simpler questionnaires which can be completed in about 5 minutes. Participants will be asked to update information in section (B) and (C) based on their activities in the past 1 month. Monthly reminder will be sent through email. Depending on the changes in epidemic level and social distancing regulation, additional updates might be requested at selected time-points.
A participant who has completed the baseline questionnaire is entitled to receive a supermarket voucher worth HKD50. Additional supermarket vouchers (each HKD50) would be offered to participants who complete at least 3 monthly updates in every 6 months (months 1-6, months 7-12, months 13-18 and so on)
Participation in this study will not subject the respondents to any foreseeable psychological, physiological, social, legal or commercial risks or benefits. Participation in this study is completely voluntary. You may quit this study whenever you wish. All data collected in this study will be kept strictly confidential and reported only in aggregate form for publicity and publication in academic journals.
