Orthohantaviruses are enveloped, segmented negative-sense RNA viruses in the order Bunyavirales (genus Orthohantavirus) whose three genome segments encode an RNA polymerase, two surface glycoproteins and a nucleocapsid protein and which cause hantavirus pulmonary syndrome in the Americas and hemorrhagic fever with renal syndrome in Europe and Asia. These viruses coevolve with specific rodent reservoirs and infect humans primarily through inhalation of aerosolized excreta. There are several factors to consider including clinical syndromes, diagnostic methods, treatment options and prevention measures that can critically influence your next steps, so see below for more details.

Orthohantavirus Gn and Gc spikes orchestrate entry into human cells by first engaging receptors such as β3 integrins, protocadherin-1, and glycosaminoglycans through their Gn tip, followed by pH-triggered conformational changes in the Gc base that drive membrane fusion and release of the viral genome. These glycoproteins assemble into tetrameric spikes that determine host range, immune recognition, and are key targets for antiviral and vaccine development. There are several important factors to consider. See the complete information below for details on receptor binding, endocytosis pathways, pH-dependent fusion, immune responses, and implications for diagnostics, treatments, and vaccine design.

Most hantaviruses cannot spread between people because they are adapted to rodent hosts, yield too low a viral load in human secretions, and lack efficient human-to-human transmission mechanisms.
