    Dengue and Zika viruses pose significant global health challenges, with millions of cases reported, particularly in Brazil.

  • 2

    Real-time RT-PCR is the gold standard for diagnosing DENV and ZIKV, but it has limitations including high costs and processing times.

  • 3

    Antigen detection via lateral flow assays shows promise for rapid diagnosis, but cross-reactivity between DENV and ZIKV complicates specificity.

  • 4

    This study employs computational modeling to identify unique antigenic regions in NS1 proteins of DENV and ZIKV for improved diagnostic accuracy.

  • 5

    Advanced bioinformatics tools like SWISS-MODEL and AlphaFold are utilized to enhance the understanding of NS1 antigenicity and epitope mapping.
