WHO warns against spread of polio from Syria to other countries
The World Health Organisation has said the spread of polio to countries previously considered free of the crippling disease is a global health emergency, Bloomberg has reported. Pakistan, Cameroon and Syria pose the greatest risk of exporting the virus to other countries, and should ensure that residents have been vaccinated before they travel, the Geneva-based WHO said. Under the recommendations adopted by WHO Director General Margaret Chan on Monday, the three countries should declare public health emergencies and ensure travellers are vaccinated and provided with documentation proving their status. In the past six months, the virus has spread to Syria, Iraq, Cameroon, Equatorial Guinea, Ethiopia, Israel and Somalia, according to the WHO.
