We've often said on this site that nature always will find new ways to infect animals (and humans) and to evolve and mutate viruses within the larger family of Orthomyxoviruses. Influenza viruses constitute just a small part of that extended family.
Recently, a novel insect-specific Orthomyxovirus, designated Sinu virus, has been detected in mosquitoes that were collected around Sinú in northwestern Colombia.
Genetic testing showed that Sinu Virus appears to be most closely related to viruses in the genus Thogotovirus.
Togotoviruses has now been expanded to nine distinct members: Thogoto Virus, Dhori Virus, Araguari Virus, Batken Virus, Jos Virus, Upolu Virus, Aransas Bay Virus, Bourbon Virus and Sinu Virus.
