Live animal markets are common hotspots for the dispersal of multiple infectious diseases in various production systems globally. In Cameroon livestock trade occurs predominantly via a system of livestock markets. Improving the understanding of the risks associated with livestock trade systems and markets is, therefore, key to design targeted and evidence-based interventions. In the current study, official transaction records for a 12-month period were collected from 62 livestock markets across Central and Southern Cameroon, in combination with a questionnaire-based survey with the livestock markets stakeholders. The available information collected at these markets was used to characterize their structural and functional organization. Based on trade volume, cattle price and the intensity of stakeholder attendance, four main classes of livestock markets were identified. Despite an evident hierarchical structure of the system, a relatively limited pool of infectious diseases was consistently reported as predominant across market classes, highlighting homogeneous disease risks along the livestock supply chain. Conversely, the variable livestock management practices reported (e.g., traded species, husbandry practices, and transhumance habits) highlighted diverse potential risks for disease dissemination among market classes. Making use of readily available commercial information at livestock markets, this study describes a rapid approach for market characterization and classification. Simultaneously, this study identifies primary diseases and management practices at risk and provides the opportunity to inform evidence-based and strategic communication, surveillance and control approaches aiming at mitigating these risks for diseases dissemination through the livestock supply chain in Cameroon.
活体动物市场是全球各种生产系统中多种传染病传播的常见热点地区。在喀麦隆，牲畜贸易主要通过牲畜市场系统进行。因此，加深对与牲畜贸易系统和市场相关风险的理解，是设计有针对性的、基于证据的干预措施的关键。在当前的研究中，收集了喀麦隆中部和南部62个牲畜市场12个月期间的官方交易记录，并结合对牲畜市场利益相关者进行的问卷调查。利用在这些市场收集到的可用信息来描述其结构和功能组织。根据交易量、牛价和利益相关者的参与强度，确定了四类主要的牲畜市场。尽管该系统存在明显的等级结构，但在各市场类别中始终报告的主要传染病种类相对有限，这突出了牲畜供应链中疾病风险的同质性。相反，报告的可变牲畜管理做法（如交易物种、饲养方式和游牧习惯）突出了各市场类别中疾病传播的不同潜在风险。本研究利用牲畜市场现成的商业信息，描述了一种快速的市场特征描述和分类方法。同时，本研究确定了有风险的主要疾病和管理做法，并提供了机会，为旨在减轻喀麦隆牲畜供应链疾病传播风险的基于证据的战略沟通监督和控制方法提供参考。
