Child coming in the prodrome of measles will look like any other child with a cold.

患有麻疹，其前驱症与感冒很像。

When there are symptoms, there might be a characteristic tingling or burning sensation, called a prodrome, one or two days before the blisters appear.

如果有症出现，可能表现为一种特有刺痛感或灼感，被称为前驱症，发在水泡出现前一两天。

For recurring episodes, these treatments usually work best if taken when the prodrome starts; in other words, before the blisters develop, and high-dose intravenous antivirals may be given in more severe, or life threatening situations.

对于复发性感染，在有前驱症时使用药物能达到最好治疗效果，也就是说，在水泡形成之前，在症严重或命垂危情况下，运用高剂量静脉注射法给抗病毒药物。
