求證：科羅拉多州蒙特羅斯市（Montrose）女子死於流感合併冠狀病毒？

科羅拉多州蒙特羅斯市（Montrose）一位名叫斯通（Almeta Stone）的女子近日對媒體爆料說，她的姐姐肖特（Lola Short）於今年1月8日去世后，她在死亡證明上發現姐姐其中一個死因，是感染了冠狀病毒。
A C.O. woman』s sister died due to sepsis, pneumonia, flu and coronavirus.
A C.O. woman』s sister died due to sepsis, pneumonia, flu and coronavirus.
「They just kept assuring us it was the flu. When I got the death certificate, it said coronavirus on there. I was so confused,」 Almeta Stone said.
COVID-19 was not confirmed.
可令斯通不解的是，醫院只和她說肖特流感，沒提冠狀病毒的事情。

是否真的？請當地的人士證實一下。
