Optimizing Provider Recruitment for Influenza Surveillance Networks

Figure 5

Augmenting an existing ILINet.

This compares theoretical upper bounds (dashed lines) to the performance of a submodular optimized ILINet built by first subsampling the zip codes of providers actually enrolled in Texas' 2008 ILINet (green) and then adding additional providers from elsewhere in the state (gray). The error bands indicate the middle 90% of resulting values, and reflect variation stemming from inconsistent provider reporting rates and informational noise.
