💬【常見問題篇】為何是次研究唔比公務員及醫管局員工參與？
本研究是由香港大學李嘉誠醫學院公共衞生學院籌辦，及由香港醫療衞生研究基金提供資金支持。為免有利益上既衝突，本研究豁除了所有公務員及醫管局人士的參與資格。

💬 [Frequently Asked Questions] Why do civil servants and Health Authority staff are ineligible for your research project?
This study is led by the School of Public Health, LKS Faculty of Medicine, The University of Hong Kong, and financially supported by the Health and Medical Research Fund of Hong Kong. This research project has excluded all civil servants and Health Authority staff so that avoids conflicts of interest.

💬【常見問題篇】我出席左今次既研究並得到陽性結果，之後有可能要被隔離或封鎖工作場所嗎？

不會！因為您的資料純粹用作為研究之用，所以不用擔心。我們亦感謝各位參加者願意繼續參與本研究！

💬 [Frequently Asked Question] I have attended the research study session before. I got the blood report with positive result. Would I be requested to go on quarantine, or the government would reinforce to restrict my workplace?

No! Your information is merely for research purposes, therefore, it is not a nuisance. On top of that, we are thankful for having your contribution in our research project!

💬【常見問題篇】為什麼我沒有病，卻會有新冠病毒的抗體？

除了打過疫苗後而產生抗體之外，有可能曾經成為「隱形病患者」。再者，身體抵抗的機制，有能力製造抗體對抗外來有害的病毒。

人口密集的環境下，只要比較多人碰過的表面已滋生了無數細菌，我們現時最關心的新冠病毒亦不例外。由於「隱形病患者」不知情，生活也是如常進行。藉此有機會感染到健康的人士，尤其當我們處於室內，空氣不流通的環境之下更具危險性。

傳染的渠道有好多種，包括：

1) 物理接觸
當我們的雙手碰過公共設施，又接觸我們的私人物品，或者未經消毒的雙手碰自己的眼﹑耳﹑口或鼻，那些病菌可以藉此感染到自己。

2) 空氣傳播
於1.5米範圍內，人與人之間的傳擂亦很高。因為身邊有機會是「隱形病患者」，而呼出來的氣，當中有水份，而病毒可經由空氣傳播到週遭。

3) 體液傳播
人的眼淚﹑鼻涕及唾液皆有可能存有病毒，因此，咳嗽或打噴嚏時，那些體液可以感染到身邊的人。

大家要好好清潔雙手，時刻戴口罩，以保護自己及他人喔！

💬[Frequently Asked Question] How come do I have the antibody for COVID-19?

Beside of vaccination to generating antibodies for coronavirus, some infected individuals can go asymptomatic. The immune response to viral infection can protect the host from a specific virus.

In such highly populated society, pathogens have already evolved to propagate on surfaces of public facility, including the most worrisome coronavirus. As asymptomatic patients have no idea whether they are infected, they just live their lives without any concerns. In the poorly ventilated areas, the virus can easily spread to one another, which is pretty risky.

There are many possible ways to spread virus throughout, for example:

1) Physical contact
If we touch the public facilities, and grab on our personal belongings; or if we have not sanitized our hands, and touch our eyes, ears, mouth or nose, the virus can infect us.

2) Airborne transmission
The infection rate is high when social distancing is within 1.5 meters between each other. As there are chances having asymptomatic patients around you, the presence of virus within droplet nuclei can remain in the air for long, thus spreading through the air to another person.

3) Droplet transmission
Tears, nasal mucus and saliva may have the virus. The potentially infective respiratory droplets can, therefore, transmit to another person in the immediate environment.

Keep your personal hygiene; wear your masks to protect yourself and others!
