About these data
In the United States, Oropouche virus disease is not currently a nationally notifiable condition. Cases are voluntarily reported to CDC by state and territorial health departments using standard interim case definitions. Arboviral surveillance data are reported to CDC through ArboNET, the national disease surveillance system.
Reports of Oropouche disease cases in other countries are provided by their respective public health agencies. Since surveillance practices vary greatly among countries, CDC does not always have accurate information on Oropouche virus transmission risk.
