  CDC is closely monitoring these variants of concern (VOC). These variants have mutations in the virus genome that alter the characteristics and cause the virus to act differently in ways that are significant to public health (e.g., causes more severe disease, spreads more easily between humans, requires different treatments, changes the effectiveness of current vaccines).
  
  The map above displays reported data on three VOCs, B.1.1.7, B.1.351, and P.1. Variants B.1.427 and B.1.429 have recently been classified as VOCs but are currently not featured on this map. Additional data is available o n Variant Proportions in the US.
