不传染了英语怎么说

在英语中，"不传染"的意思可以用"non-contagious"来表达。
"Contagious"是从拉丁语"contagium"中派生出的，意思是"传染物"或"传染病"。加上"non-"前缀后，就成了"不传染的"的意思。
以下是一些例句：
The flu is usually contagious, but this strain appears to be non-contagious. (流感通常是传染性的，但这种流感似乎是不传染的。)
Is this illness contagious or non-contagious? (这种疾病是传染性的还是不传染性的？)
The doctor said the rash was non-contagious and not to worry about it spreading to others. (医生说这种皮疹是不传染的，不用担心会传染给别人。)
