Step-by-step explanation:
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person. I believe this is a virus because virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
my recommendation for polio prevention is Poliomyelitis vaccine should be given at 2, 4, and 12 to 18 months and 4 to 6 years of age, for a total of four doses at or before school entry. For children who receive OPV only, the third dose may be given as early as 6 months of age in accordance with prior recommendations.
