What is the pathogenesis and disease caused by Rhabdovirus?
P: Animal bite (saliva). Invariably fatal without post-exposure prophylaxis.
D: Encephalitis
What is the pathogenesis and disease caused by Picornavirus?
P: Droplets or fecal-oral. Diverse family of viruses causing a wide range of diseases.
D: Respiratory tract infections, hand-foot-mouth disease, conjunctivitis, CNS infections, myocarditis
