Virus Can Be Transmitted by Various Means: Expert 專家:空氣.不當接觸.環境 都可能傳播病毒

Of the 8 newly-confirmed cases, 6 were staying in nearby rooms on the same floor, which experts say indicated that the situation could be airborne transmissions, or the hotel staff or guests did not strictly follow disease prevention guidelines. 
 


There was another cluster infection in a Taoyuan quarantine Hotel. Case 16851 who returned to Taiwan from China was diagnosed on the 7th day of the self-health management period, with a Ct value of only 19.2. The Central Epidemic Control Center quickly initiated retrospective tracing and found a total of eight positive cases on three floors of the hotel. Six of the cases were on the same floor in adjacent rooms. Domestic experts believe that there may be three causes of this cluster infection.

Huang Li-min, Honorary Chair, Infectious Diseases Society of Taiwan: “Was the video reviewed? First, did you see the 6 infected people meet each other? If they didn't meet each other, then check the hotel staff and how they came in contact with the guests. If you can't confirm the cases were caused by hotel staff by reviewing the video, then you have to consider air conditioning. Because this virus can be spread through air conditioning.”

Huang said if multiple people are diagnosed as a result of air infection, they may have to check whether there are problems with the hotel's air conditioning and ventilation. In addition, it is also necessary to check whether the confirmed cases have complied with regulations and if they made contact with the outside world during quarantine. Furthermore, the virus may have also spread if staff did not disinfect the plate when collecting it and touched other doorknobs.

Hsueh Chih-ming, Quarantine Hotel Operator (Not This Case Involved): “Before guests move in or after they checkout, the air conditioner filter must be removed and cleaned. After washing with bleach, it must be wiped with alcohol to disinfect.”

Quarantine hotel operators believe whether staff training is implemented following the SOP is very important. The local health department will also perform inspections on a regular basis. The surrounding environment, including the food delivery cart, is regularly disinfected, and the staff is fully protected during the entire time. If all the above have been implemented thoroughly, it is very likely that the air-conditioning filter has not been disinfected carefully. After all, the hotel's air-conditioning still uses central air-conditioning, and the virus may have spread through this channel. 
 

 

 

桃園防疫旅館再爆發群聚感染,一位從中國返台的案16851於自主健康管理第七天時確診,Ct值只有19.2,指揮中心緊急專案回溯採檢結果發現防疫旅館三個樓層共有八人染疫,其中六人是同一層樓且房間相鄰,對此國內專家認為,造成這件事的傳染途徑,可能有三種。

台灣感染症醫學會名譽理事長黃立民指出:「錄影帶本身有沒有看到,第一,有沒有看到被感染的六個人互相有見面,如果他們互相沒有見面,那就看旅館的人員跟他們是怎麼接觸的,如果錄影帶看起來也不能確定是這些旅館的人員造成的,那你就要考慮空調,因為病毒是可以經過空調傳播的。」

黃立民表示,如果是空氣傳染所造成多人確診,可能就要去檢查防疫旅館空調、通風是否出現問題。另外也要去看確診者有沒有遵守規定,在檢疫旅館期間跟外界接觸。另外,服務員收沾染病毒餐盤後未消毒,並觸碰到其他人的門把」,也都可能造成病毒傳播。

其他防疫旅館業者薛志民說:「客人住進來之前或者是在他checkout(退房)之後,空調的過濾網是必須拆下來之後一一去清洗,經過漂白水去全部的清洗之後,還要再用酒精擦拭去消毒。」

防疫旅館業者認為,員工培訓是不是有按照SOP去執行是相當重要的一環,地方衛生局也都會不定時來稽查,且包括餐車四周環境都有定期消毒,加上工作人員都會全副武裝執行任務,如果上述都已徹底執行,很有可能就是空調過濾網消毒不夠仔細,畢竟飯店冷氣還是走中央空調,就擔心病毒會透過此途徑去傳播。
