Countries in West Africa will in the next three days begin a drive in a move to eradicate polio. In all, about twenty million children are expected to be vaccinated during this period. Hundreds of thousands of volunteers have been mobilised in eight countries to help administer the oral vaccine.

The United Nations Children's Fund is working with the various health ministries to try to rid Africa of the highly contagious and incurable virus. It spreads easily in densely populated countries with poor sanitation, according to a BBC report.
Rumours
Great strides have been made in the fight against polo in recent years, but the virus which causes paralysis has not been eradicated in West Africa partly because previous efforts at vaccination have been met with suspicion by some religious leaders in Nigeria.
The battle against polio received a major set-back in 2003 when a vaccination programme in northern Nigeria had to be abandoned after rumours spread that the polio vaccine caused Aids and was part of a western plot to sterilise Muslim girls.
As a result the virus then spread and re-infected 23 countries which had earlier been declared polio free.
Ghana had recorded no new cases of polio for five years until just a few months ago when eight cases were identified - the children between the ages and one and four were all paralysed.
The ongoing effort to eradicate polio is not cheap - in Ghana alone $2.5m (£1.7m) will be spent over the next three days.
