• Authorities report six deaths in central Argentina linked to the bacterial disease.
• Animal surveillance detected 517 canine notifications with 107 positives, underscoring shared exposure sources.
• About 85% of confirmed and probable human cases are concentrated in Buenos Aires, Santa Fe and Entre Ríos, with additional reports across multiple provinces.
