Polio
"An infectious waterborne disease, polio can spread rapidly through human faeces.
It can affect people of any age, but children under five are the most vulnerable
– comprising about 50 per cent of all cases. The virus invades the nervous
system and can cause irreversible paralysis within hours, mostly in the legs,
and without any sign of prior illness. " (Unicef)
