The CDC-APHL Influenza Virologic Surveillance Right Size project was launched in 2010 to systematically define the rationale, vital capabilities, and optimal "right size" for influenza virologic surveillance. This website provides the resulting Roadmap and other valuable information and tools. 

The first edi​tion of the roadmap was published in 2013 and consolidated requirements for all components of virologic surveillance in one document, and provided tools to assess and improve the precision of the system to support disease surveillance, response and control efforts and policy decisions. A second edition of the roadmap was published in 2022. 

The Influenza Virologic Surveillance Right Size Roadmap​​ 2nd Edition aims to identify shifts in the availability and use of different data sources through a careful reevaluation and redesign of the original roadmap. It provides updated information, narrows the target audience to public health laboratory and influenza program staff, and attempts to clarify and simplify its messages, particularly around sample size goals. The second edition clearly outlines sample size goals by state​. ​Use the link above to download the entire roadmap, including appendices.
