Experts Weigh in on Academia Sinica Case 前中研院人員遭鼠咬染疫 專家提質疑

Was the former Academia Sinica researcher infected by a lab mouse? Toxi-cologists say it is unlikely unless something extremely unusual happened. It is also very unusual that the woman's boyfriend tested negative, but he could still be in the incubation period.


Toxicologists say it is "highly unusual" that the former Academia Sinica researcher tested positive for the Delta variant after being bitten by a lab mouse infected with the Alpha variant, especially since the researcher was probably very careful at work. Therefore, something "extremely unusual" must have happened along the way. They also say the woman's medical history must be thoroughly examined as she failed to report her symptoms when they developed and went to see a doctor on her own.

Chao Ming-wei, Associate Professor, Chung Yuan Christian Uni.: “COVID-19 is (spread) via droplets, so this is pretty unusual. (In addition, the infected person) went and got medical treatment on her own. She exposed a lot of people.”

One expert says the boyfriend of the woman testing negative could be due to him being vaccinated or still being in the incubation period, and he should be monitored. Epidemiologist Huang Li-min, meanwhile, believes the woman being bitten by lab mice in October, developing a cough in November, and losing her sense of taste and smell in December are unrelated.

Huang Li-min, Epidemiologist: “You need to see if she was working with the Delta variant at the Academia Sinica. Genome sequencing will tell you if she did, especially since she was just infected. If she was infected in her community, the genome sequencing would be different.”

Zen Lin, Chair, Taiwan Primary Care Association: “If there are no new cases for several weeks, the chances of new cases after those weeks are very low. If cases continue appearing, Taiwan should be prepared for the next wave of community-level infection like we saw in May and June.”

Doctors say the next two to four weeks will be key given that the woman's source of infection is unknown. They also say anyone living or working in the same area as the woman, that develops symptoms, should get a PCR test.

 

 

 

前中研院實驗室人員確診Delta病毒株,毒理學專家分析,被Alpha老鼠咬到卻得了Delta,確實很不尋常,再者實驗室的操作應該是非常嚴謹,他直指在嚴謹的情況下卻還能確診,中間的過程非常不尋常,更何況在出現症狀後,第一時間沒有通報自行就醫,過程必須要徹底被檢討。

中原大學生物科技學系副教授招名威表示:「可是新冠病毒它是透過飛沫(傳染),所以這個地方其實蠻特別的,(又)私下去自行就醫,最後導致確診,還影響這麼多層面的群眾。」

專家認為,這名確診者的男友,目前採檢陰性,有可能是疫苗保護奏效,或是還在潛伏期,後續要密切觀察。感染科醫師黃立民則點出,這個個案的感染源還有待釐清,個案在10月初被實驗室老鼠咬傷,11月底出現咳嗽症狀,12月出現嗅味覺異常確診,應該是三個獨立事件。

感染科醫師黃立民表示:「看她最近操作的病毒,在中研院操作的病毒,有沒有操作Delta病毒,基因序列一比對就知道了,因為她剛得到,所以基因序列會幾乎是一樣的,如果她在社區得的,基因序列就一定會不一樣。」

基層醫療協會理事長林應然表示:「如果前一兩個禮拜都沒有案例,我想後面有案例的機會也會減少很多;如果前一兩個禮拜案例一直在出現,我覺得台灣又要重新來個下一波,5、6月的那種社區感染的模式。」

醫師認為,因為還無法確認感染源,接下來兩週甚至一個月,都是要特別注意的觀察期,尤其個案生活圈的周邊診所,對於有任何疑似症狀的患者,最好都進行PCR採檢,才有機會篩出確診者,進行防堵。
