- POLIO IN THE WORLD, JANUARY-APRIL 2012
Polio this week - As of 09 May 2012
In the first four months of 2012, the lowest number of cases globally over a four-month period has been recorded over the past ten years, with 53 cases from four countries (the bulk of which – 95% – from the three remaining endemic countries). Only three cases have occurred from a non-endemic country (all from Chad, and none since February). At this time last year, 12 countries had reported 145 cases. More than 50% of this year’s cases are from Nigeria, which now constitutes the Global epicenter of polio transmission.
