The promise of precision health is to transform a healthcare system that is today based on treating sickness to harnessing a range of technologies to predict and prevent illness. Health 2.0’s Technology for Precision Health Summit in San Francisco October 24 will explore the state of precision health and what’s needed to make it a reality. We spoke to Linda Molnar, chair of the summit, about precision health, what gaps in the healthcare continuum need to be addressed to create a healthcare system geared toward prediction and prevention, and how companies will make a business out of this.
