Abstract: A method of classifying an infectious disease in a subject are disclosed. The method comprises: (a) measuring the amount of at least one protein set forth in Table 4 and at least one protein set forth in Table 6 in a sample derived from the subject; and (b) ruling in or ruling out a viral disease based on the amount of the at least one protein set forth in Table 4 and determining the severity of the viral disease based on the amount of the at least one protein set forth in Table 6.

Abstract: Methods of determining infection type are disclosed. In one embodiment, the method comprises measuring the amount of a determinant which is set forth in Tables 1 or 2 in a sample derived from the subject, wherein said amount is indicative of the infection type.

Abstract: A method of selecting an exon of an RNA whose expression level is informative with respect to infection type of a subject is disclosed. The method comprises comparing the expression level of the RNA in a sample derived from a bacterially-infected subject and a sample derived from a virally-infected subject at a plurality of exons, wherein the exon that provides a differential expression between the bacterially-infected subject and the virally-infected subject above a predetermined level is selected as the exon of the RNA whose expression is informative with respect to infection type.
