Explanation:
Polio, or poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus. The virus spreads from person to person and can infect a person's spinal cord, causing paralysis (can't move parts of the body).
Symptoms vary from mild flu-like symptoms to life-threatening paralysis. In less than 1% of cases, polio causes permanent paralysis of the arms, legs or breathing muscles. Between 5% and 10% of people who develop paralytic polio will die. Physical symptoms may emerge 15 years or more after the first polio infection.

Answer:
Polio (poliomyelitis) mainly affects children under 5 years of age.
1 in 200 infections leads to irreversible paralysis. Among those paralysed, 5% to 10% die when their breathing muscles become immobilized.
Cases due to wild poliovirus have decreased by over 99% since 1988, from an estimated 350 000 cases then, to 33 reported cases in 2018.
As long as a single child remains infected, children in all countries are at risk of contracting polio. Failure to eradicate polio from these last remaining strongholds could result in as many as 200 000 new cases every year, within 10 years, all over the world.
In most countries, the global effort has expanded capacities to tackle other infectious diseases by building effective surveillance and immunization systems.
