Bats provide many ecosystem services and have intrinsic value. They also act as host reservoirs for some viruses. Several studies have linked zoonotic diseases to bats, raising questions about the risks bats pose, especially to people living close to bat roosts. Through a series of case studies undertaken in three communities, the purpose of this paper is to explore the various ways in which framings and perceptions of bats can influence a potential spillover of bat-borne viruses to humans in Ghana. It assesses the social, cultural and economic factors that drive human-bat interactions and posits that understanding the socio-economic contexts in which human-bat interactions occur is key to the success of future communication strategies.
Primary data collection methods included participatory landscape mappings, transect walks, focus group discussions and questionnaire surveys. Perceptions of bats vary and are influenced by personal beliefs, the perceived economic benefits derived from bats and the location of bat roosts.
An Ebola outbreak of unprecedented scope emerged in West Africa in December 2013 and presently continues unabated in the countries of Guinea, Sierra Leone, and Liberia. Ebola is not new to Africa, and outbreaks have been confirmed as far back as 1976. The current West African Ebola outbreak is the largest ever recorded and differs dramatically from prior outbreaks in its duration, number of people affected, and geographic extent. The emergence of this deadly disease in West Africa invites many questions, foremost among these:why now, and why in West Africa? Here, we review the sociological, ecological, and environmental drivers that might have influenced the emergence of Ebola in this region of Africa and its spread throughout the region. Containment of the West African Ebola outbreak is the most pressing, immediate need. A comprehensive assessment of the drivers of Ebola emergence and sustained human-to-human transmission is also needed in order to prepare other countries for importation or emergence of this disease.
Rift Valley fever (RVF) is an important neglected, emerging, mosquito-borne disease with severe negative impact on human and animal health. Mosquitoes in the Aedes genus have been considered as the reservoir, as well as vectors, since their transovarially infected eggs withstand desiccation and larvae hatch when in contact with water. However, different mosquito species serve as epizootic/epidemic vectors of RVF, creating a complex epidemiologic pattern in East Africa. The recent RVF outbreaks in Somalia (2006–2007), Kenya (2006–2007), Tanzania (2007), and Sudan (2007–2008) showed extension to districts, which were not involved before.
These outbreaks also demonstrated the changing epidemiology of the disease from being originally associated with livestock, to a seemingly highly virulent form infecting humans and causing considerably high-fatality rates. The amount of rainfall is considered to be the main factor initiating RVF outbreaks. The interaction between rainfall and local environment,
Outbreak narratives have justified rapid and sometimes draconian international policy responses and control measures. Yet there is a variety of other ways of framing haemorrhagic fevers. There present different views concerning who is at risk, and how? Is the ‘system’ of interacting social-disease ecological processes a local or a global one, and how do scales intersect? Should haemorrhagic fevers be understood in terms of short-term outbreaks, or as part of more ‘structural’, long-term social-disease-ecological interactions?
What of the perspectives of people living with the diseases in African settings? And what of uncertainties about disease dynamics, over longer as well as short time scales? This paper contrasts global outbreak narratives with three others which consider haemorrhagic fevers as deadly local disease events, in terms of culture and context, and in terms of long-term social and environmental dynamics. It considers the pathways of disease response associated with each,
