It is intended to provide a new method for predicting the severe respirator infections. The problem is solved by a method for assisting in predicting the severity of the respirator infection, the method comprising: a step for measuring a biomarker in a subject collected from a subject suffering from the respirator infection or a subject suspected of the respirator infection. The biomarker is at least one selected from the group consisting of IFN lambda3, CCL17, CXCL11, IP-10, IL-6, and CXCL9, and the measured value of the biomarker is used as an index for predicting the severity of respirator infection.
