World facing polio health emergency

The WHO has stated the spread of polio is an international public health emergency. The polio outbreaks in Asia, Middle East and Africa. It pose the greatest risk of further wild poliovirus exportations in 2014. The situation is extraordinary event needing an international cooperation. People who travel abroad need to vaccinate. Polio mainly affects children under five years old. The virus is infected through contaminated food and water, and capable of causing death within hours. I think an international response is essential so that we prevent the polio virus from spreading all over the world.
