Which of the following is a clinical sign associated with the late phase of leptospirosis?

In the late phase of leptospirosis, the clinical signs become more severe as the disease progresses. One of the most critical manifestations during this phase is pulmonary hemorrhage, which occurs due to the damage leptospirosis can inflict on the blood vessels and the lungs. This can lead to respiratory distress and significant morbidity. Jaundice can also develop due to liver involvement, as leptospirosis can cause hepatic dysfunction and result in the accumulation of bilirubin in the bloodstream.

Recognizing these signs is vital for timely intervention and management of leptospirosis. Understanding the progression of the disease through its various phases helps veterinarians anticipate potential complications and decide on appropriate treatments. The presence of pulmonary hemorrhage and jaundice indicates a severe and potentially life-threatening situation, underscoring the importance of recognizing these late-phase signs.
