====Hosts====
*Horses and Man
*Reservoir host: birds, mosquitoes
====Pathogenesis====
*Virus oscillates between definitive and reservoir populations
*'''Aseptic encephalitis''' with concurrent '''fatalities'''
====Epidemiology====
*Virus originated in Africa
*Two versions seem to exist:
**Old world '''avirulent''' strain
**New world '''virulent''' mutant
*Entrance to US via mosquitoes was followed by a rapid sweeping spread across the country with deaths of horses and birds
*UK birds show antibody but no reported deaths
====Diagnosis====
*Virus isolation
*RT-PCR on CSF
====Control====
*Vector control (mosquitoes): drain standing water, sprays, etc
