There is little solid scientific knowledge about how influenza, the common cold and stomach flu spread and how to protect against them because the necessary research has not been done, according to researchers at Interdisciplinary Scientific Research, a research and consulting firm in Seattle. As a result, in rigorous evaluations, strategies recommended by medical experts to avoid these illnesses have not consistently reduced rates of illness.

Interdisciplinary Scientific Research launched the Health Tracking Network in April 2011 with the following goals:

1) Identify factors related to common illnesses.
2) Promote members' health by enabling them to track their personal health, fitness, and other variables easily.
3) Generate donations to charities chosen by members.
4) Provide researchers access to a high-quality sample of respondents for scientific survey questions at low cost.
