"受疫情的影响" 在英语中可以用 "affected by the pandemic" 来表达。
"Pandemic" 来源于希腊语 "pan-" 和 "demos"，意思是"全国"或"全民"，所以 "pandemic" 在英语中表示一种在全球范围内流行的疾病。
一些例句：
The pandemic has affected the economy in many ways. (疫情对经济造成了很多影响。)
Many people have lost their jobs due to the pandemic. (由于疫情，很多人失去了工作。)
Schools have had to adapt to the pandemic by switching to onpne classes. (学校不得不通过转到网络课程来适应疫情。)
