![Sensitivity of detecting various numbers of additional counts, by using initial versus best algorithms for hospital emergency department chief complaint data, for selected BioSense data. Red line shows the initial algorithm (minimum SD = 0.2, 7-day baseline, count method, unstratified baseline), and black line shows the best algorithm (minimum SD = 1.0, 28-day baseline, rate method, unstratified baseline).](/eid/images/08-0616-F2.jpg)
