Risk Assessment for COVID-19
These categories are interim and subject to change. Please check often the CDC.gov website. This website is not intended to be kept current.
These categories may not cover all potential exposure scenarios. They should not replace an individual assessment of risk for the purpose of clinical decision making or individualized public health management.
State and local authorities have primary jurisdiction for isolation and other public health orders within their respective jurisdictions. Federal public health authority primarily extends to international arrivals at ports of entry and to preventing interstate communicable disease threats. Please follow all authorities’ guidelines and orders.
