Sangassou orthohantavirus (SANGV) is single-stranded, negative-sense RNA virus species of the genus Orthohantavirus in the Bunyavirales order. It was first isolated in an African wood mouse ( Hylomyscus simus) in the forest in Guinea, West Africa in 2010. It is named for the village near where the mouse was trapped. It is the first indigenous Murinae-associated African hantavirus to be discovered. [2]
Genome
The virus genome consists of three segments of negative-stranded RNA; the large (L) segment encodes the viral RNA-dependent RNA polymerase, the medium (M) segment encodes the envelope glycoproteins Gn and Gc (cotranslationally cleaved from a glycoprotein precursor), and the small (S) segment encodes the nucleocapsid (N) protein. [2]
Renal syndrome
In rodents, hantavirus produces a chronic infection with no adverse sequelae. In humans, hantavirus produces two major clinical syndromes: hemorrhagic fever or pulmonary syndrome. European, Asian, and African rodent-borne hantaviruses cause hemorrhagic fever. The pulmonary syndrome, caused by the species Sin Nombre orthohantavirus, has not been found anywhere other than the United States[ dubious ] where deer mice are the natural hosts. It was discovered in 1993 during an outbreak in the Four Corners region of the southwestern United States. [3] [4]
Reservoirs
Natural reservoirs for this hantavirus species include the slit faced bat, moles, and shrews. Rodent-borne hantaviruses form three major evolutionary clades corresponding to the subfamilies of their rodent hosts. HTNV, SEOV, and DOBV are examples of Murinae-associated hantaviruses. PUUV and Tula orthohantavirus (TULV) belong to the Arvicolinae-associated hantaviruses, and SNV and ANDV are representatives of Neotominae- and Sigmodontinae-associated hantaviruses. [2] [5]
