“全球疫情严重”常见英文表达有：The global pandemic is severe、The pandemic situation is serious worldwide、COVID-19 remains a severe global health crisis。正式语境可用the global pandemic situation is grave。
- pandemic指全球大流行，比epidemic范围更大；
- severe/serious强调严重程度，critical偏危急；
- 新闻标题常用global pandemic worsens或worldwide outbreak remains severe。
翻译时需结合语境，避免直译“严重”为serious而忽略搭配。
