香港大學感染及傳染病中心總監何栢良表示，早前與港大微生物學系講座教授袁國勇分析了本港首23個確診武漢肺炎的患者身體所含的病毒數量，發現他們在入院當日病毒量最高，1滴口水的份量更可帶有10萬粒病毒，能存在人體長達21日。
何栢良指出，確診患者在入院當日，口水、鼻涕及痰液的病毒量十分高，即使過了14日，病毒量依然維持在一個高水平。21日後，患者的病毒量水平仍未算低，所以不少人無法出院。談及患者入院當日的病毒量情況，他表示每1毫升就可以帶有1億粒病毒，並指「一滴好似芝麻咁細嘅口水鼻涕水點」就能帶有10萬粒病毒。
由於人體對武漢肺炎（新冠肺炎）沒有免疫力，只需幾粒病毒足以受感染。何栢良提醒醫護人員在接收懷疑個案及確診個案時要特別小心，除了按照指引正確配戴保護裝備，亦應有人在旁監督，確保整個感染控制的過程滴水不漏。在收工回家之前，醫護人員亦應先清潔全身，包括洗頭。
另外，何栢良提醒大眾，應儘量避免在外用餐，建議大家買外賣回家用餐。即使在外進食，用餐時避免與他人交談，亦應與其他人保持6個階磚的安全距離，實在沒有辦法可以考慮面壁食飯等「自閉用餐」方法。
