Study Notes
Bunyavirus Characteristics
- Has a negative sense RNA genome
- Enveloped virus that obtains its envelope from the Golgi body of host cells
- Segmented genome with three circular segments
Hantavirus
- Transmitted through rodents, particularly Deer mouse, and their urine and pellets
- Can cause death
- Causes pulmonary edema via capillary leak and prerenal azotemia
- Characterized by hemorrhagic fever, fever, and sweating
- Hantavirus (Sin Nombre virus) spreads through rodent urine or feces aerosol, causing pulmonary syndrome
- Symptoms of pulmonary syndrome include cough, tachycardia, pulmonary edema and effusion, and hypotension
Other Bunyaviruses
- Rift Valley Fever, transmitted by Aedes mosquito, causes seizures, encephalitis, and can affect school children
