Africa to be declared polio-free. The World Health Organization (WHO) is set to certify on Tuesday that the African continent is free from wild polio, four years after the last cases appeared in northeastern Nigeria.

How did people get polio?
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. Polio is more common in infants and young children and occurs under conditions of poor hygiene.
How was polio cured?
Once the virus that causes polio has infected a person, there is no treatment that will cure polio. Early diagnosis and supportive treatments such as bed rest, pain control, good nutrition, and physical therapy to prevent deformities from occurring over time can help reduce the long-term symptoms due to muscle loss.

Why does Pakistan still have polio?
By 1991, only 83 percent of Pakistani children had been vaccinated. Research by the Center for Disease Control (CDC) in April 1998 cited a failure to vaccinate, vaccine failure, and inadequate immunization strategies as causes for the continued incidences of polio in this time.
Is the world polio free?

WHO declares Africa polio free?
A global initiative was started in 1988 with the aim of eradicating the spread of wild poliovirus. To be certified polio-free, a region has to have gone 3 years without the virus being isolated from a person with paralysis, and in Africa this was from a person in Nigeria in 2016.
When was Australia declared polio-free?
2000Australia, along with the Western Pacific Region, was declared polio-free in 2000.
