The C-19 Index

What It Is

The C-19 Index is an open source, AI-based predictive model that identifies people who are likely to have a heightened vulnerability to severe complications from COVID-19 (commonly referred to as “The Coronavirus”). The C-19 Index is intended to help hospitals, federal / state / local public health agencies and other healthcare organizations in their work to identify, plan for, respond to, and reduce the impact of COVID-19 in their communities.

What It’s NOT

To be absolutely clear – the C-19 Index does NOT predict who will become infected with COVID-19 or geographic locations where the virus might spread. It is meant to identify people with a heightened risk of severe complications should they become infected.

How protecting our most vulnerable people helps fight COVID-19

A percent of people who become infected with COVID-19 will have severe complications, require treatment with mechanical ventilators in intensive care units (ICUs) and possibly die. To prevent this – and prevent overloading the healthcare system – we need to identify those individuals now and find practical solutions to help them “shelter in place” so they don’t need to leave their homes.

The C-19 Vulnerability Survey

Your COVID-19 Vulnerability score may help determine if you or a loved one have a heightened vulnerability to severe complications from COVID-19.  By knowing your vulnerability risk to severe complications, you can learn how to best protect yourself from exposure to COVID-19, and take every measure to protect your health and that of your loved ones.

The C-19 Vulnerability Survey

What It Is

The COVID-19 Vulnerability Survey (C-19 Vulnerability Survey) is a tool for individuals to use that helps them understand whether they or a loved one have a heightened vulnerability to severe illness from COVID-19. By gaining a more complete view into their own vulnerability or that of a loved one, individuals have a tool they can use as they mobilize resources to protect themselves and their families.

What It’s NOT

To be absolutely clear – the C-19 Vulnerability Survey is NOT designed to diagnose whether you have contracted COVID-19 or to predict whether you will contract COVID-19. The survey is designed to use your survey responses to assess your vulnerability to developing serious complications in the event you contractCOVID-19.

The information provided, including the results of the vulnerability survey, is NOT professional health care advice and should not be used to diagnose, treat, prevent, or cure any disease or condition, including COVID-19. Never disregard professional medical advice or delay seeking medical care because of something you have read in this survey or on this website.

How are you using my data?

By taking the survey and receiving your vulnerability score, you are contributing to advance vital research on COVID-19, and helping to provide critical resources to those most affected by the virus.

We respect every individual’s right to privacy. You have the option to allow us to use the information you provide towards furthering research, or to not share your data at all. If you select “Delete My Data”, your data will be erased immediately after we provide your risk score.

If you do decide to share your information with us, we promise to never share your data with anyone else, and you will always have the option to request that we delete your data at a later date.
