Dengue virus (DENV) typically co\u2010circulates with other clinically and antigenically similar flaviviruses, such as Zika virus (ZIKV). The clinical diagnosis is difficult and accurate serological analysis represents an unmet challenge. Traditionally, serological analysis of DENV infection focuses on the acute phase via detection of NS1 or IgM. Developing IgG DENV\u2010specific assays has been defiant due to the co\u2010circulation of four antigenically distinct serotypes and a strong cross\u2010reactivity with other arboviruses, particularly with ZIKV. The goal of this study was to produce recombinant domain III of the Envelope (EDIII) proteins of each DENV serotype and ZIKV and evaluate the ability to detect specific IgG antibodies. The antigens were tested on the ELISA platform to measure DENV\u2010specific IgG in mice and patients infected with ZIKV and DENV. The assay differentiated serotype\u2010specific IgG responses in susceptible mice (AG129) experimentally infected with DENV or ZIKV. In addition, the test demonstrated a robust performance achieving 87.8% sensitivity and 91.4% specificity when tested against 648 well\u2010characterized sera collected from humans infected with DENV and\/or ZIKV. The test was further applied to serum samples collected from 318 healthy individuals from an endemic region in Northwest\/Central Brazil, without a previous diagnosis of DENV, and revealed that 65% of the samples reacted with at least one DENV serotype antigen, including 123 monotypic samples (88 for DENV\u20101) and 90 samples reacting with multiple antigens. Collectively, these results indicate that the IgG DENV\u2010EDIII ELISA is a valuable tool for assessing the serological status of populations in endemic areas, particularly in regions where other flaviviruses, particularly ZIKV, co\u2010circulate and offer support to establish public health policies against the disease.<\/jats:p>","DOI":"10.1002\/jmv.70100","type":"journal-article","created":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T11:09:29Z","timestamp":1733137769000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Serotype\u2010Specific
