MOGADISHU: Africa has marked one year since the last case of recorded polio, with the United Nations celebrating Wednesday a key step towards eradicating the disease.
The last recorded case on the continent was in Somalia on August 11, 2014, although health officials must wait two more years before declaring the continent free from the highly infectious, crippling virus.
The UN children´s agency UNICEF, which plays a key role in polio vaccinations, called it an "extraordinary achievement" but warned it was "not an end point".
Success depends on the continuation of vaccination campaigns and close monitoring of possible cases, it said.
"We have had no new cases for a year despite all the challenges in the country," UNICEF´s chief for Somalia Steven Lauwerier told AFP on Wednesday.
"We never want to see another Somali child being paralysed by this preventable virus. That means we need to continue to support the vaccination campaigns to ensure polio is completely eradicated."
Nigeria marked one year since its last recorded case of polio in July. It is one of only three countries -- along with Pakistan and Afghanistan -- where the virus remains endemic.
Nigerian health ministry spokesman Dan Nwomen said Wednesday said the anniversary was "welcome" but stressed the "momentum should be sustained" through improved immunisation campaigns.
"Globally, we are on the verge of totally eradicating a disease for only the second time in history," UNICEF polio chief Peter Crowley said, referring to the elimination of smallpox.
