The correlation of the HealthMap Flu Trends estimates with the observed CDC ILI rates is 0.99 for 2013-2015. Additional data sources lead to an error reduction of about 40% when compared to the estimates of the model that only incorporates CDC historical information. Conclusions: While the advantages of participatory surveillance, compared to traditional surveillance, include its timeliness, lower costs, and broader reach, it is limited by a lack of control over the characteristics of the population sample. Modeling and simulation can help overcome this limitation as well as provide real-time and long-term forecasting of influenza activity in data-poor parts of the world. %M 29092812 %R 10.2196/publichealth.7344 %U http://publichealth.www.mybigtv.com/2017/4/e83/ %U https://doi.org/10.2196/publichealth.7344 %U http://www.ncbi.nlm.nih.gov/pubmed/29092812
