透過在Google搜尋相關字眼[2],可找到俄羅斯《衛星通訊社》(Sputnik)於6月24日的相關報導[3],報導引述《華盛頓郵報》(The Washington Post)一篇文章指部分曾參與2019年世界軍人運動會的運動員宣稱出現類似COVID-19的症狀、描述當時的武漢為「鬼城」,美國國會隨後開始調查此事。
與上述軍運會傳言類似,過往亦有關於美國2019年夏季爆發的美國「電子煙肺病」(e-cigarette, or vaping, product use-associated lung injury, EVALI)與COVID-19的傳言。[15]
美國疾病控制與預防中心(Centers for Disease Control and Prevention,CDC)網站上有關於EVALI的資訊,提及病例於2019年8月急劇增加,同年9月達到高峰。CDC又指維他命E醋酸酯(Vitamin E acetate)與是次爆發有緊密關連(strongly linked),同時未有足夠證據排除其他化學物的影響。[16]
圖2︰CDC網站上的圖表顯示,美國EVALI病例自2019年9月中開始回落。
一項於2020年2月在《新英格蘭醫學雜誌》(The New England Journal of Medicine, NEJM)刊登的論文顯示了維他命E醋酸酯與EVALI的關聯。該項研究分析了51個EVALI病人的支氣管肺泡灌洗液(BAL fluid)樣本,並與99個並無患上EVALI的健康參與者的樣本對比。51個EVALI病人分別來自美國16個州,當中25人確診、26人列作可能個案;作為對照組的健康參與者中有18人使用電子煙、29人吸傳統煙、52人為非煙民。分析結果發現,51個EVALI病人當中,有48人的樣本檢測到維他命E醋酸(3個未檢測到的均為可能個案),而對照組所有樣本均沒有檢測到。
見[5],相關段落原文為 “As the covid-19 pandemic took hold worldwide in early 2020, athletes from several countries — including France, Germany, Italy and Luxembourg — claimed publicly they had contracted what they believed to be covid-19 at the games in Wuhan, based on their symptoms and how their illnesses spread to their loved ones. In Washington, military leaders either dismissed the idea out of hand or weren’t aware of it. Meanwhile, no one performed any antibody testing or disease tracing on these thousands of athletes. No one even attempted to find out whether the games in Wuhan was, in fact, the first international pandemic superspreader event.”
