  • In Madagascar, a circulating vaccine-derived poliovirus type 1 (cVDPV1) has been confirmed. The virus was isolated from one case of acute flaccid paralysis (AFP) with onset of paralysis on 29 September, and from three healthy contacts. An estimated more than 25% of children remain under-immunized against polio in the country. Madagascar was previously affected by a cVDPV2 outbreak in 2001/2002 (resulting in five cases) and in 2005 (resulting in three cases). Emergency outbreak response is being finalized, with campaigns to be held in December and January.

As does the risk of a mass polio outbreak

28 March 2013 - The harvest has come and gone but the Sahel region of west and central Africa remains in crisis. OCHA estimates that more than 10 million people will remain food insecure throughout 2013, including 1.4 million children under five suffering from acute malnutrition. At the same time, insecurity in Mali is pushing people to flee their homes and their country; and for those that remain (particularly in the North), the price of food is rapidly rising.

Intense virus transmission in northern Nigeria, large-scale population movements and lack of funds make for dangerous situation

West Africa just comes off the heels in stopping a multi-country polio outbreak that affected 12 countries from 2009 to 2011, caused 281 cases and cost US$94 million to control. But the threat of a renewed outbreak now looms as large as ever.

09 May 2012 description

Polio transmission is heating up in northwestern Nigeria just as populations move back along traditional stock routes and into areas now affected by conflict, such as Mali.

In Nigeria, authorities are focusing on making sure vaccination activities are well-implemented in the northwest of the country, particularly in Sokoto and Zamfara states. It is from this area that poliovirus has in the past spread into west Africa, causing outbreaks in previously polio-free areas. This risk is currently magnified by the security situation in Mali, and associated population movements.
