Somalia has recorded its first wild poliovirus case since 2007, the WHO announced on May 11, Nature’s “News Blog” reports. “Genetic testing to determine the virus’s origin is underway and should be complete this week, according to a WHO representative,” the blog writes. Polio immunization campaigns have not taken place in some parts of Somalia because of conflict, the blog notes, adding the country plans to vaccinate 350,000 children in one region beginning May 14 and a nationwide campaign is being discussed, according to the WHO (Callaway, 5/13).
