Lassa Fever: a rodent-human interaction

This resource examines the sites of interactions between humans and the multimammate mouse, Mastomys natalensis. It presents findings such as new arenaviruses in other African rodents and in snakes, that  argue preferably toward the host-switching concept. The recent emergence in Sierra Leone, the absence of virus positive Mastomys between the two endemic zones and poor virus diversity in the Mano River area also point in the direction of a unique import of Lassa virus from Nigeria to Sierra Leone during the 19th century. This resource also discusses the hypothesis of human displacements through the Atlantic slave trade and its abolition in 1807.

The process and practice of diagnosis: Innovations in diagnostics for Lassa fever in Sierra Leone

Chapter 5 of Annie Wilkinson’s PhD thesis, provides a detailed description of health seeking behaviours for Lassa Fever in rural Sierra Leone. In this context, people interpreted and managed Lassa Fever in light of their familiarity with a wide range of other diseases, some of which were viewed as dangerous and others less so; in contexts where sickness, health and treatment were marked by uncertainty; and where hospitals were not necessarily perceived to be sites of good care.  An important insight is that people differentiated ‘big sick’ or ‘hospital sick’ from an ordinary or ‘small’ sick and it was partly on the basis of this distinction that people would choose to access care.

Emerging disease or emerging diagnosis?: Lassa fever and Ebola in Sierra Leone

This article looks beyond Ebola in 2014 to the history of efforts to control VHFs in the Mano River and challenges the idea that there was a vacuum of knowledge. Highlighted instead are politics of knowledge which have run through global health and which have prioritized particular forms of knowledge and ways of dealing with disease. Ethnographic research on the emergence of Lassa and the subsequent emergence of Ebola in West Africa is presented, focusing on the development of technologies and institutions to detect and manage both viruses.
