Some studies show that people with allergic asthma appear to have lower levels of a receptor for the COVID-causing virus.

一些研究也显示过敏性哮喘患者的的新冠病毒受体水平似乎较低。

I had an allergic asthma from growing up in the city of Philadelphia, downtown, and so I used an inhaler and it made it better.

我在费城市区长大，得过过敏性哮喘，所以我使用了吸入器，它让我的病情大大缓解了。
