Nigeria has just been removed from the list of polio endemic countries in the world, a polio endemic country is where polio disease is always or regularly present. The milestone was achieved due to Nigeria going more than one year without a case of wild (naturally occurring) polio.
The announcement was made by the World Health Organization in New York at a meeting of the Global Polio eradication Initiative (GPEI).
However to be declared a polio free country, Nigeria must not have a case of wild polio for three full years.
Polio (A.K.A. Poliomyelitis) is an extremely contagious and debilitating disease caused by the polio virus. It occasionally causes death but the infection leads to paralysis, death results if the respiratory muscles are paralyzed. Polio is only found in human and spreads from person to person through food, water and hands contaminated by faeces (stool) containing the virus. Uncovered food can also be contaminated by flies carrying faces containing the virus. The virus attacks the brain and the spinal cord.
