What historical name is sometimes used for the severe manifestation of leptospirosis involving vital organ damage?

Answer

Weil's disease

When leptospirosis progresses beyond the initial non-specific phase into a more serious condition marked by systemic spread and vital organ involvement, this severe manifestation is historically referred to as Weil's disease. This nomenclature is significant because it denotes a stage where complications like jaundice and acute renal failure are likely present. The progression to Weil's disease indicates that the *Leptospira* bacteria have disseminated throughout the bloodstream and begun causing severe, potentially life-threatening damage, particularly to the liver and kidneys.
