While snakebite in pregnant women has been sporadically reported and is known to be associated with significant obstetrical complications, envenomation in animals, particularly in pregnant horses, is exceedingly rare. Only a few isolated cases of snakebite in horses have been documented, and to the best of our knowledge, snakebite in a pregnant mare has not been previously reported in the medical or veterinary literature. Russell's viper (Daboia russelii) envenomation is a major cause of morbidity and mortality in South Asia. We describe the first documented case of severe Russell's viper envenomation in a 5.5-year-old Marwari mare at 9 months of gestation following confirmed double bites to the muzzle. The mare developed rapidly progressive craniofacial oedema, respiratory compromise and severe venom-induced consumption coagulopathy with recurrent rebound coagulopathy. Management required intensive monitoring and administration of an unusually high cumulative dose of equine polyvalent antivenom totalling 60 vials. Despite the high venom burden, pregnancy-associated bleeding risk and delayed venom redistribution from facial tissues, the mare achieved complete clinical recovery with preservation of foetal viability. This case highlights the unique challenges of snakebite management in pregnant large animals, including venom depot effects, recurrent coagulopathy and foetal risk. Aggressive antivenom therapy guided by coagulation monitoring can result in favourable maternal and foetal outcomes.

First, we reviewed published literature to synthesize knowledge related to disease transmission by leeches. Second, we collected terrestrial leeches (genus Haemadipsa) from human-occupied rainforests in Peninsular Malaysia and applied metagenomic methods for virus discovery to their anterior segments.

Eswatini, a low-endemic country in Southern Africa, transitioned over four decades from a centralized institutional model of leprosy care to integrated service delivery within primary healthcare. From 2000 to 2024, only sporadic adult cases were detected, with no child cases reported for over two decades. This paper describes lessons from sustaining elimination during this transition. Key interventions included integrating leprosy diagnosis and treatment into primary healthcare, maintaining referral-level clinical expertise, routine zero-reporting via DHIS2, case-based surveillance with household contact tracing, and embedding leprosy indicators within national neglected tropical disease policies. The programme also implemented the WHO-recommended Leprosy Elimination Monitoring Tool (LEMT) and Leprosy Programme and Transmission Assessment (LPTA) to support verification. The Eswatini experience shows that sustaining interruption in low-burden settings requires continuous surveillance, minimal technical expertise, social inclusion, sustained political commitment, and cross-border collaboration to prevent re-establishment among mobile populations. WHO-verification processes drove programme strengthening by identifying gaps and reinforcing accountability. These lessons may inform other low-endemic countries progressing toward verification and the WHO target of zero leprosy by 2030.</p>","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148866403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
