# School Influenza A Heatmap

A guide to reading the heatmap: 

Each week, two samples are collected from the school’s manhole and analyzed for Influenza A. The Influenza A analysis results for each school for each week is represented by a square on the heatmap. If a square is red, then Influenza A was detected in both samples from that school on that date, and the results are designated as Positive. If a square is green, then Influenza A was not detected in the two samples from that school on that date, and the results are designated as Negative. If a square is yellow, then Influenza A was detected in one sample from the school but not in the other sample, and the results are designated as Inconclusive. Lastly, if a square is white, then the school’s wastewater was not sampled that week.
