Answer 1

(i)

All the statements are true except first. The poliomyelitis virus infects central nervous system rather than throat and small intestine. It is transmitted through contaminated food and water. It causes muscle paralysis but in most cases the infection is asymptomatic. The vaccine for treatment contains live attenuated virus or weakened virus.
