Market characteristics and zoonotic disease risk perception in Cameroon bushmeat markets

Résumé fourni par la source

Behavioral practices are one of the key factors facilitating zoonotic disease transmission, especially in individuals who have frequent contact with wild animals, yet practices of those who work and live in high-risk animal-human interfaces, such as wild animal 'bushmeat' markets in the Congo Basin are not well documented in the social, health and medical sciences. This region, where hunting, butchering, and consumption of wild animal meat is frequent, represents a hotspot for disease emergence, and has experienced zoonotic disease spillover events, traced back to close human-animal contact with bats and non-human primates. Using a One Health approach, we conducted wildlife surveillance, human behavioral research, and concurrent human and animal biological sampling to identify and characterize factors associated with zoonotic disease emergence and transmission. Research was conducted through the USAID Emerging Pandemic Threats program between 2010 and 2019 including qualitative studies of bushmeat markets, with selected study sites prioritized based on proximity to bushmeat markets. Sites included two hospitals where we conducted surveillance of individuals with syndromes of acute febrile illness, community sites where we enrolled actors of the animal value chain (ie. hunters, middlemen, transporters), and bushmeat markets, where we enrolled bushmeat vendors, butchers, market managers, cleaners, and shoppers. Mixed methods research was undertaken at these sites and included investigation of bushmeat market dynamics through observational research, focus group discussions, quantitative questionnaires, and interviews. Participants were asked about their risk perception of zoonotic disease transmission and specific activities related to bushmeat trade, local market conditions, and regulations on bushmeat trade in Cameroon. Risks associated with blood contact and animal infection were not well understood by most market actors. As bushmeat markets are an important disease interface, as seen with CoVID19, risk mitigation measures in markets and bushmeat alternative strategies are discussed.
