China review links human and canine leptospirosis evidence

Version 1

A new systematic review and meta-analysis in Preventive Veterinary Medicine pulls together the available evidence on human and canine leptospirosis in China, aiming to map prevalence patterns and associated risk factors across both species. The review was PRISMA-compliant, searched six databases through November 11, 2025, and positions leptospirosis as a shared human-animal-environment problem rather than a siloed veterinary or public health issue. The paper appears in Preventive Veterinary Medicine as article 106855, with PubMed listing PMID 41864068. (eurekamag.com)

Why it matters: For veterinary professionals, the value is less about a single new outbreak signal and more about consolidation. Leptospirosis remains a persistent zoonotic threat in China even as broader national incidence has declined over time, and recent Chinese literature has argued for stronger integrated surveillance linking human case data, animal infection data, and environmental risk. Separate recent work from China also suggests dogs may serve as useful sentinel animals for human leptospirosis risk, especially in urbanized settings and along changing rainfall belts. That makes this review relevant for clinicians, diagnosticians, and public health veterinarians thinking about vaccination, differential diagnoses, and One Health surveillance design.

What to watch: Watch for follow-on papers or surveillance guidance that translate this evidence synthesis into region-specific canine vaccination, testing, and One Health monitoring strategies in China. (pmc.ncbi.nlm.nih.gov)
