Like most people who have grown up in the UK, I used to think of polio as more or less eradicated.
We're in the final round of an epic fight. Now is not the time to flinch - now is the time where together we make history.
For at least 20 of the athletes who competed in the Games in London this year, it is polio which has left them paralysed - a vicious, highly infectious disease that attacks the nervous system and can cause paralysis, if not death. It is children under five who are most vulnerable to infection. But it was possible to watch London 2012's Paralympics Games with a great sense of optimism. These Games were historic, not only for the number of competing athletes and sell-out crowds, but also because they may well have been the last Olympics to take place in a world where a child is at risk of paralysis because of polio.
David Njenga is sitting at home--a dank, claustrophobic room in Rongai--with his wife and two young children. Perhaps ironically
We have a window of opportunity to capitalise on India's achievement and make a real push to protect every child against polio. I want to know that, wherever I travel on this planet of ours, I will never again find a child whose life has been damaged forever by polio.
When given access to their fundamental rights, disabled people can achieve the equality that enables them to make vital contributions to society, improving their lives and the lives of others.
So long as a single child remains infected with polio, the global goal of eradication will not be met. We must also look inwards to put in place critically-needed health system reforms, which will be vital for meeting any development target in Pakistan where social divides are widening at an alarming pace.
