Leptospirosis: a globally increasing zoonotic disease

Area of Science:

• Infectious Diseases
• Public Health
• Clinical Medicine

Background:

• Leptospirosis, also known as Weil's disease, is a bacterial infection typically found in tropical regions.
• Its incidence is rising in temperate climates, posing a growing public health concern.
• Severe manifestations, including pulmonary involvement, are increasingly reported in these regions.

Observation:

• A previously healthy 27-year-old man in Ireland presented with severe jaundice, dyspnea, hemoptysis, anemia, thrombocytopenia, and acute kidney injury.
• Clinical and laboratory findings were consistent with icteric leptospirosis.
• Exposure was linked to building a shed in his garden, suggesting environmental contact as a transmission route.

Findings:

• Serological testing confirmed the diagnosis of leptospirosis.
• The patient received a 7-day course of intravenous ceftriaxone.
• Complete recovery was achieved following treatment.

Implications:

• This case underscores the re-emergence of potentially fatal leptospirosis in temperate zones.
• Increased clinical awareness is crucial for timely diagnosis and management of severe leptospirosis cases.
• Environmental risk factors, even in non-tropical areas, should be considered in the differential diagnosis of severe febrile illnesses.
