Banna virus

Banna virus (BAV) is a virus that belongs to the genus Seadornavirus, within the family Reoviridae. It was first isolated in 1987 from patients with encephalitis and febrile illness in the Xishuangbanna Dai Autonomous Prefecture in Yunnan province, China.

Overview

BAV is a double-stranded RNA virus and is known to be transmitted by mosquitoes. It has been detected in a wide range of mosquito species, including Culex tritaeniorhynchus, Culex pipiens pallens, and Anopheles sinensis. The virus has been isolated from humans, pigs, and mosquitoes in China, Indonesia, and Vietnam.

Clinical Presentation

The clinical presentation of BAV infection in humans is not well defined. However, it has been associated with febrile illness, encephalitis, and meningitis. The severity of the disease can range from mild to severe, and in some cases, it can be fatal.

Diagnosis

Diagnosis of BAV infection is typically made by serology or polymerase chain reaction (PCR) testing. Serology involves detecting antibodies against the virus in the patient's blood, while PCR involves detecting the presence of the virus's genetic material.

Treatment and Prevention

There is currently no specific treatment or vaccine for BAV. Management of the disease is primarily supportive, focusing on relieving symptoms and preventing complications. Prevention strategies include controlling mosquito populations and avoiding mosquito bites.
