Tensaw virus is a virus in the genus Orthobunyavirus of the Bunyamwera arbovirus group, family Bunyaviridae.[1][2] It is named for the river bordering the area in south Alabama where the prototype strain was discovered.[1] It is abbreviated TEN, TENV, and TSV in the scientific literature.[1]
Ecology
Tensaw virus has been isolated from mosquitoes in southwest Alabama, southeast Georgia, and central and south Florida.[3][4] Host mosquitoes include Anopheles crucians, Psorophora ciliata, Psorophora confinnis, Anopheles quadrimaculatus, Aedes atlanticus, Aedes mitchellae, Culex nigripalpus, and Mansonia perturbans.[1][3][5]
Disease
The virus produces clinical disease and death in suckling and adult mice but not in hamsters, guinea pigs, or rabbits.[1] Antibodies or virus have been detected in dogs, raccoons, cattle, and humans, but no evidence of infection has been found in sentinel chickens or wild birds.[3]
Serum samples from humans in south Florida have tested positive for neutralizing antibodies to Tensaw virus,[2][6] but clinical disease from Tensaw virus infection in humans had not been reliably demonstrated as of 2006.[7]
Evidence that Bunyamwera serogroup viruses in North America are associated with congenital defects such as macrocephaly and/or microcephaly in humans suggests the possibility that Tensaw virus and other viruses of the family Bunyaviridae may have teratogenic potential in humans.[8]
