Distinguishing between Zika and dengue virus infections is critical for accurate treatment, but we still lack detailed understanding of their impact on their host. To identify new protein signatures of the two infections, we used next-generation proteomics to profile 122 serum samples from 62 Zika and dengue patients. We quantified >500 proteins and identified 13 proteins that were significantly differentially expressed (adjusted p-value < 0.05). These proteins typically function in infection and wound healing, with several also linked to pregnancy and brain function. We successfully validated expression differences with Carbonic Anhydrase 2 in both the original and an independent sample set. Three of the differentially expressed proteins, i.e., Fibrinogen Alpha, Platelet Factor 4 Variant 1, and Pro-Platelet Basic Protein, predicted Zika virus infection at a ∼70% true-positive and 6% false-positive rate. Further, we showed that intraindividual temporal changes in protein signatures can disambiguate diagnoses and serve as indicators for past infections. Taken together, we demonstrate that serum proteomics can provide new resources that serve to distinguish between different viral infections. Analysis of human serum samples with extreme protein abundance ranges Unique protein signatures for Zika and dengue virus infection Temporal changes in protein signatures as indicators for past infections Machine learning to account for confounding factors Differentiation between the mosquito-borne Zika and dengue Flavivirus infections is clinically important for correct treatment, but remains challenging. We used mass spectrometry to quantify expression levels for 277 proteins measured in serum samples from 62 patients, providing a resource to the community. We identified 13 proteins with significant differential expression between the closely related types of infections. Most of the proteins link to pregnancy and brain function. We also identified expression signatures that mark ambiguous infections with respect to temporal differences.
