(Treat this like a flu... In many cases when you catch this, it's very light. You don't even know there's a problem.)
(患上新冠肺炎)有時候只會流鼻水。有時只會感到不太舒服。有時感覺會很糟。但這都與流感相似。
(Sometimes they just get the sniffles. Sometimes they just get something where they're not feeling quite right. And sometimes they feel really bad. But that's a little like the flu.)
