Outbreak in Lao
'In October, a child paralysed by cVDPV type 1 was confirmed in Lao PDR. Soon, three more people with paralysis were confirmed as the virus spread. An outbreak response was quickly mobilised to vaccinate all children under the age of 15 with the oral polio vaccine. In 2015, outbreaks of cVDPV have been found in Guinea, Madagascar, Nigeria and Ukraine as well as in Lao PDR, occurring because vaccination levels have been low for extended periods of time.'
