National Daily Health Survey

For Novel Coronavirus (COVID-19)

Our goal is to learn and predict which geographical areas will be most impacted by coronavirus based on how you are feeling.  This information will be used to inform local and national responses, such as redirecting medical resources or improving policies and public guidance.  Given the 9-10 day delay between onset of symptoms and hospitalization, and the 20% hospitalization rate of patients, tools like this will be necessary to truly track and fight the spread.

Your involvement will hopefully help save lives. As a country, we are all in this together!

Stanford Medicine is currently experiencing a high volume of survey responses.  As we work to
bring this tool to a national audience, please continue to try the link in the event that you
experience a technical issue. Your daily response is very important to this initiative!

How does it work?

We will ask you a series of short questions, which will be displayed just like most messaging applications.  The first day you participate, this should take about 2-3 minutes, with the assessment each day after taking only about 1 minute.

The more information we gather, the better our understanding of Novel Coronavirus will be, so we ask:

• Respond daily. With your permission, we can send you a daily email prompt
• Share the link on social media

The information will be used, along with local test results, to predict surges and severity of Novel Coronavirus by region to guide health officials on when shelter in place orders could be safely lifted. 

This is a research study. You will be asked to agree to participate after reading the consent form. 

If you have questions about the tool or would like to get involved, please contact the team at
