WHO, the United States Centers for Disease Control and Prevention and the European Centre for Disease Prevention and Control have developed a new Zika virus classification scheme. The classification serves to categorize the presence of and potential for vector-borne ZIKV transmission and to inform public health recommendations. Based on the defined criteria and expert review, some countries, territories and subnational areas were reclassified and some were classified for the first time.
In line with WHO’s transition to a sustained programme to address the long-term nature of the disease and its consequences, this is the final WHO Zika situation report. WHO will continue to publish the Zika classification table (Table 1) on a regular basis as well as periodic situation analysis.
