Structural communication links identified for human (A) and swine (B) influenza surveillance in Alberta. Information is usually shared from left to right: from laboratories, through the Provincial Surveillance Initiative system, back to the patients and referring physicians, as well as surveillance groups within the provincial government. Some information (anonymized) also flows to the federal government: from veterinarians, laboratories, and abattoirs to Swine Health Intelligence Networks (e.g., CWSHIN and CSHIN) to governments (provincial and federal). There is also publicly available information shared by the Community for Emerging and Zoonotic Diseases to various stakeholders (from right to left). Dashed lines: samples; Full lines: data; Dotted lines: results/summaries. Blue: field stakeholders; Yellow: laboratories; Purple: intelligence; Red: government.
