Screening for Coronavirus Antibodies in Neighborhoods (SCAN)

Homepage

About the Study

We are studying how many people have developed antibodies to the COVID-19 virus.  We want to include people from the many neighborhoods that make up our community.  Research is important and can help our city and its many neighborhoods.  We believe the safety of people who take part in our research is the most important thing. This study was reviewed by an independent committee who has the mission to protect rights and wellbeing of people who take part in research. If you have any specific worries or questions about being in SCAN, please contact us.

SCAN is trying to find out how many people in specific areas were exposed COVID-19.   COVID-19 is an infection caused by a virus.  Normally the body develops antibodies to help fight off viruses.  We are measuring how many people have antibodies to COVID-19.  The SCAN Study will help us learn if these antibodies protect people against re-infection.  We will do this by asking questions about your health.  We will also measure how much antibodies are in your blood.  Many people seem to develop antibodies to COVID-19 without ever having been sick.

We will test the blood spots you provide us to see if you have COVID-19 antibodies, how long the antibodies last, and if the antibodies can protect you against re-infection. Antibodies usually come in the blood a few weeks after a virus like COVID-19.  Some people get antibodies sooner than others, and we are learning that many people develop antibodies without ever having symptoms of COVID-19. Having antibodies might mean you are protected from future infection by COVID-19. We hope to learn about this by asking about your health.

We will store leftover blood spots. We may use them in future research at Northwestern or other places unless you withdraw from the study. We will use your survey responses to learn if certain communities are more likely to have antibodies. Your data may help us learn what protects people or puts them more at risk for COVID-19. 

The law requires us to report positive cases to local health departments. Our reports will include your name, date of birth, and address as well as the test results.
