Аннотация
BACKGROUND: Co-circulation of Plasmodium vivax and arboviruses is a significant but underexplored public health concern in tropical regions.
METHODS: We analyzed 300 serum samples collected between 2014 and 2015 from the Brazil-French Guiana border, including 102 malaria cases and 198 controls, using rapid tests for Immunoglobulin M (IgM), Immunoglobulin G (IgG), and Non-Structural Protein 1 (NS1).
RESULTS: High IgG reactivity for dengue and chikungunya viruses was observed. Co-reactivity was frequent. Zika virus detection was minimal.
CONCLUSIONS: The overlapping transmission of P. vivax and arboviruses highlights the need for integrated surveillance strategies to better address co-circulation/co-infection risks.
