The Comeback Of Polio Is A Public Health Emergency
It is, says the World Health Organization, “an extraordinary event.” Polio is spreading to a degree that constitutes a public health emergency.
The global drive to wipe out the virus had driven the number of polio cases down from 300,000 in the late 1980s to just 417 cases last year. The World Health Organization has set a goal of wiping out polio by 2018.

Bruce Aylward, the head of WHO’s polio program, says if the international spread isn’t halted, the virus could easily re-establish itself, particularly in conflict-torn countries like the Central African Republic and South Sudan. The unrest makes it difficult to sustain vaccination efforts, and poor sanitary conditions cause the disease to spread.
Although polio mainly afflicts children under 6, a WHO emergency committee has stated that adults are to blame. The committee noted that there is “increasing evidence that adult travelers [from Pakistan, Syria and Cameroon] contributed” to the polio surge.

In addition, WHO is calling for the three countries to continue efforts to inoculate their children.
