The region is one of the agro-pastoral livelihood zones in Somaliland, where farming and agricultural production are the predominant livelihood sources. IGAD (Intergovernmental Authority on Development) Sheikh Technical University of Science (ISTUS) worked to study the prevalence of Bovine Tuberculosis (TB) among cattle in Awdal region of Somaliland. The aim was to inform public health and Veterinary experts on having one-health approach to infectious diseases among humans and animals. The serum that was stored at -20˚C was transported to IGAD Sheikh Technical University of Science (ISTUS) for further analysis using BOVIGAM serological test (Sandwich ELISA). The results indicate that Bovine Tuberculosis is highly prevalent in the study area (10.1%). The high prevalence recorded in the current study could be due to the consumption of raw milk and lack of proper control strategies in place to control the transmission of the disease between animals, between animals and wildlife and between animals and humans. Hence, an awareness creation campaign should be created on bTB transmission and its public health significance to cattle owners, milk and meat consumers and people who are in close proximity to cattle. In addition, testing and eradication programme should be implemented where applicable.","PeriodicalId":17559,"journal":{"name":"Journal of Tuberculosis Research","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135698917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To assess whether intensified case finding (ICF) strategies at NRCs can lead to pediatric case detection among SAM children and link them to TB treatment under the Revised National Tuberculosis Control Programme (RNTCP). Materials and Methods A retrospective cohort study was conducted that included medical record reviews of SAM children registered for TB screening and RNTCP care during July–December 2012. Results Among 440 SAM children screened, 39 (8.8%) were diagnosed with TB. Among these, 34 (87%) initiated TB treatment and 18 (53%) were registered with the RNTCP. Of 16 children not registered under the RNTCP, nine (56%) weighed below six kilograms—the current weight requirement for receiving drugs under RNTCP. Conclusion ICF approaches are feasible at NRCs; however, screening for TB entails diagnostic challenges, especially among SAM children. However, only half of the children diagnosed with TB were treated by the RNTCP. More effort is needed to link this vulnerable population to TB services in addition to introducing child-friendly drug formulations for covering children weighing less than six kilograms.","PeriodicalId":17559,"journal":{"name":"Journal of Tuberculosis Research","volume":"4 1","pages":"46-54"},"PeriodicalIF":0.0,"publicationDate":"2016-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4826071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34741749","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}
