Abstract excerpt

Dengue is one of the most rapidly expanding mosquito-borne viral diseases worldwide, posing a persistent public health challenge across tropical and subtropical regions. Here, we report the re-emergence of dengue virus serotype 3 (DENV-3) in Paraguay following approximately 15 years without confirmed detection. In early 2025, twelve laboratory-confirmed cases were identified in the metropolitan region of Asunción...
