**human receptor: nAChR, NCAM, p75NTR - all developed only in nerve cells
==responsible animals==
*''Lyssavirus'' circulates within a same animal species
**sometimes transmitted to other species - "spillover" phenomenon
*can infect all warm-blooded animals
==pathophysiology==
*retrograde fast axonal transport CNS 15-100mm/day
*spread from CNS to peripheral nerve
*incubation 4-13 weeks, occasionally up to 6 years
*despite catastrophic clinical outcome, histopathological changes in CNS are quite mild
**macroscopically unremarkable
**microscopically minimal changes characterized by perivascular cuffing of mild degeneration of neuron, microglial activation
==transmission route to human==
*99.99% animal bites
*aerosol inhalation
**in cave where infected bats live
*organ transplantation
*unrecognized exposure
**ingestion of infected dog meat
**butchering of infected dog
