Anti-polio drive in Egypt after Pakistan-link virus found
An emergency polio vaccination programme is to be carried out in the Egyptian capital, Cairo, after samples of the virus were found in sewage.
The World Health Organisation (WHO) says the strain of virus matches one found in southern Pakistan.
No-one in Cairo has shown any symptoms of the disease and there have been no cases of polio in Egypt since 2004.
