Fort Sherman virus
Fort Sherman virus is a single-stranded, negative sense, tri-segmented RNA virus. The virus is closely related to Cache Valley virus. There are multiple strains of the virus, each with individual characteristics including the Panama, Brazil, and Argentina strains. Of the three strains, the Panama strain is the only reassortment of them. Research suggests reassortment during the genealogy of the Panama strain. This was found while analyzing the M segment of the virus in which the Brazil and Argentina strains closely matched while the Panama strain matched closely with CVV. The L and S segments matched closely for all three strains.
