La dengue - malattia virale causata dalla puntura di zanzare del genere aedes aegyptique - sembra essersi trasformato nel 2023 in Argentina in una letale epidemia, visto che al momento si registrano già 39 morti, considerato un record storico, e almeno 41'257 casi. Questi ultimi sono al di sopra di quelle verificatisi negli anni scorsi, e in particolare il 48,4% in più del 2020, anno in cui si erano avuti 26 decessi.
Il portale di notizie Infobae indica che i 39 decessi attuali sono distribuiti in nove zone: provincia di Buenos Aires (1), città di Buenos Aires (2), Jujuy (6), Salta (10), Santa Fe (7), Santiago del Estero (1), Tucumán (9), Entre Ríos (1) e Córdoba (2).
In tutti i campioni studiati è stato rilevato il sierotipo 2-Cosmopolitan, che finora non circolava in Argentina, ma in Brasile e Perù. Si tratta di un sierotipo Denv-2 originario del sud-est asiatico.
