Researchers have identified a previously unknown virus, thought to be transmitted by ticks or other insects, that led to the death of a farmer in Kansas (USA) during the summer of 2014. The first symptoms were fever, low red and white blood cell counts, elevated liver enzymes and loss of appetite. The illness was fast-moving and severe, causing lung and kidney failure, and shock. The man, previously healthy, died after about only 10 days in the hospital.
The newly discovered infectious agent has been named the Bourbon virus, which has been named after Bourbon County, part of Kansas City, where the patient had lived. Laboratory tests finally determined that the virus belongs to the ever expanding family of Orthomyxoviruses.
What this discovery demonstrates is that the Orthomyxoviruses, a family that also harbours the Influenza viruses, is seemingly expanding at a hightened pace. The Bourbon Virus is deadly, even for healthy individuals.
The Bourbon Virus belongs to the Thogotoviruses and that makes it a direct relative of the influenza viruses because all are part of the larger family of Orthomyxoviruses. The genus Togotoviruses has nine known distinct members: Thogoto Virus, Dhori Virus, Araguari Virus, Batken Virus, Jos Virus, Upolu Virus, Aransas Bay Virus, Bourbon Virus and Sinu Virus.
