This detection in immunocompetent children challenges the traditional association of L. <em>infantum</em> solely with VL and highlights its capacity for atypical dermal manifestations. These findings underscore the necessity of molecular diagnostics to differentiate <em>Leishmania</em> species, as misidentification risks ineffective treatments and potential disease progression. Enhanced surveillance integrating PCR-based methods is critical to track dermal strains in regions where VL and CL overlap, particularly given potential ecological or genetic drivers of atypical tropism.

Therefore, the present study aimed to determine the magnitude of these two important zoonotic diseases and the associated risk factors in south Achefer district, northwest Ethiopia. A cross-sectional study was carried out in June and August of 2020. The research cattle, which belonged to farmers in three selected localities, were chosen by a simple random sampling method.

Here, we report the first record of <em>C. paraensis</em> in Cuba, during the first known outbreak of Oropouche fever outside its endemic range in the Amazon region. Using human landing catches, we collected 98 specimens of <em>C. paraensis</em> in three Cuban provinces (Santiago de Cuba, Cienfuegos, and Havana), where Oropouche fever had been documented in humans. This species was not captured using various traps deployed at the sampling sites (BG-Sentinel, New Jersey traps, and CDC light traps), which may explain why <em>C. paraensis</em> had not been previously reported in Cuba. In North America, <em>C. paraensis</em> develops in wet treeholes, while in tropical regions, it uses cacao husks and banana stumps as larval habitats. However, the specific larval development sites for this species in Cuba are unknown. The capture of adult female <em>C. paraensis</em> in areas of active Oropouche virus circulation suggests their involvement in virus transmission in Cuba.</div></div>","PeriodicalId":37873,"journal":{"name":"Parasite Epidemiology and Control","volume":"29 ","pages":"Article e00423"},"PeriodicalIF":2.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
