International audience Hantaviruses (family Hantaviridae, genus Ortho-hantavirus) are RNA viruses transmitted by aero-solized excreta from infected rodents and shrews. In humans, they cause hemorrhagic fever with renal syndrome (more often observed in Asia and Europe) and cardiopulmonary syndrome (more common in the Americas) (1). Only 1 case has been confirmed in Africa, in the Central African Republic in 1987 (2). However, studies from 2006 through 2013 have discovered new hantaviruses in autochthonous African rodents, moles, and bats (3,4). In addition, serologic evidence in humans and rodents in Africa suggest local circulation (5). For example, a study in rural areas of Senegal found 11.5% of rodents and 16.6% of humans had antibodies against hantaviruses (3). More recently, serologic evidence of hantaviruses was reported in domestic and peridomestic rodents from some regions in Senegal (6). Southeastern Senegal has become a major trade area because of urbanization and substantial improvement of its road and rail networks in the late 1990s (7). Within a few years, these changes led to the rapid spread of a major invasive rodent species, the black rat (Rattus rattus [family Murinae]), which is a reservoir for Seoul orthohantavirus (SEOV) (4,5,7). To assess the prevalence of hantaviruses in rodents, we screened for hantaviruses in R. rattus rats and commensal or peridomestic co-existing rodents in 2012–2013, approximately 15 years after the 1998 opening of a tarred road in eastern Senegal.
