D: Respiratory tract infection
What is the pathogenesis and disease caused by Reovirus?
P: Fecal-oral. Can be serious for infants.
D: Gastroenteritis
What is the pathogenesis and disease caused by Togavirus?
P: Droplets or vertical. Teratogenic.
D: Rubella, congenital rubella syndrome.

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
What is the pathogenesis and disease caused by Calicivirus?
P: Fecal-oral, food, water, or aerosolization. Seasonal epidemics.
