The document discusses the rabies virus. It belongs to the order Mononegavirales and family Rhabdoviridae. Rabies virus is bullet-shaped and contains a single-stranded RNA genome that encodes for 5 proteins. These proteins and the genomic RNA determine the structure of the virus particle. The virus infects the central nervous system of mammals and is usually transmitted through bites from rabid animals. Common symptoms include fever, headache, and later delirium. Diagnosis can be made using direct fluorescent antibody tests or immunohistochemistry. Treatment after symptoms have appeared is generally only supportive as rabies is nearly always fatal. Prevention focuses on vaccinating domestic animals and avoiding contact with wild animals.
