The World Health Organization (WHO) has said 11 countries in South-East Asia were polio-free. Its website said: "This is the fourth of six WHO regions…marking an important step towards global eradication of polio – a highly infectious virus." Around 80 per cent of the world is now polio-free. One newly-certified country is India. In 2009, it had half of the world's polio cases. It hasn't seen a single case of polio for the last three years.
Polio is incurable. It attacks the nervous system and can paralyse in hours. It can result in death. A WHO doctor said it was a "momentous victory for the millions of health workers" who helped rid polio from the region. She said it showed how working together could help future generations. She warned against becoming lazy in the fight against the disease. She said polio was still a global risk and that Asia's polio-free status was still "fragile".
Back to the polio lesson.
