Huaiyangshan banyangvirus

Huaiyangshan banyangvirus is a species of virus in the genus Banyangvirus, family Phenuiviridae, and order Bunyavirales. It is known to cause severe fever with thrombocytopenia syndrome (SFTS), a tick-borne infectious disease that can be fatal in humans.

Taxonomy

Huaiyangshan banyangvirus is a member of the Banyangvirus genus, which is part of the Phenuiviridae family. This family belongs to the order Bunyavirales, which comprises nine families of RNA viruses. The Banyangvirus genus includes several other species of viruses, such as the Heartland virus and the Severe fever with thrombocytopenia syndrome virus (SFTSV).

Transmission and Disease

Huaiyangshan banyangvirus is primarily transmitted to humans through tick bites, particularly from the Haemaphysalis longicornis tick. It can also be transmitted through contact with the blood or body fluids of an infected person.

The virus causes severe fever with thrombocytopenia syndrome (SFTS), a disease characterized by high fever, gastrointestinal symptoms, thrombocytopenia (low platelet count), and leukocytopenia (low white blood cell count). In severe cases, it can lead to multi-organ failure.

Diagnosis and Treatment

Diagnosis of Huaiyangshan banyangvirus infection is typically confirmed through laboratory testing, including polymerase chain reaction (PCR) and serologic testing.

Treatment for SFTS caused by Huaiyangshan banyangvirus is primarily supportive, as there is currently no specific antiviral treatment available. Management of the disease involves treating the symptoms and complications, and may include hospitalization, intravenous fluids, and treatment for pain and fever.

Prevention

Prevention of Huaiyangshan banyangvirus infection primarily involves avoiding tick bites through the use of insect repellents, wearing long sleeves and pants, and performing regular tick checks after being in tick-infested areas.
