Document Summary
Ex: large amt. of main capsid proteins (vp6) versus small amount of vp1s virion assembly: vp7 and nsp4 syn. Prevention and treatment of rotavirus infection: rehydrate pt. w/ solution of salt and sugar, gatorade/sports drinks not good irritate intestinal tract, 2 vaccines rotateq and rotarix. Other dsrna viruses: family cystoviridae, naked virions w/ icosahedral symmetry, always enclosed within virus protein structures in order not to triggered host antiviral mechanisms. Poliomyelitis now present only in north & central. Rapid identification/surveillance important: disappearance, 57,000 cases in 1952 in us less than 100 cases in 1961. Coxsackie viruses: isolated in 1948 in coxsackie, cause range of medical conditions, myocarditis (heart disease), meningitis, rashes. Rhinoviruses: most common agents causing upper resp. tract infections in humans, account for 50% of common colds, replicate in epithelium of upper resp. tract, where temp. is around. 33-35 degrees: many can replicate at 37 degrees responsible for lower resp. tract disease, more than 100 are known.
