Healthcare providers, medical labs, and other entities report conditions to public health departments, varying by jurisdiction. Case notifications for national notifiable conditions are voluntarily submitted to CDC. NNDSS data are provisional and subject to change until reconciled with state and territorial providers. Weekly cumulative counts may increase or decrease as updates occur. Finalized annual data often differ from provisional counts. CDC aggregates data for national notifiable diseases and conditions on a weekly and annual basis. To see specific surveillance Case Definitions for this disease, go to: https://ndc.services.cdc.gov/
