Improving Polio Vaccination Coverage in Nigeria Through the

AbstractMethodsResultsDiscussionNotesIn 1988, the World Health Assembly launched the Global Polio Eradication Initiative (GPEI), and in 2012 declared the completion of polio eradication a programmatic emergency for global public health. The virus is still endemic in 3 countries: Pakistan, Afghanistan, and Nigeria. Experts generally agree that Nigeria is a key battleground in the war against polio. Although the country made impressive gains in 2010, reducing the number of cases of wild poliovirus (WPV) infection to 21, from 500 in 2009, the number of polio cases in Nigeria rose dramatically over the next 2 years, totaling 97 and 122 in 2011 and 2012, respectively. Security issues, religious and sectarian opposition, a decentralized government lacking a strong federal arm, widespread corruption, poor literacy rates, and extreme poverty are all acknowledged to be factors in Nigeriarecent lack of progress. These social, economic, and political issues, however, are complex and will likely not be resolved in the foreseea...Get price
