Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this research is to gather information to answer questions about the Coronavirus Disease 2019 (COVID-19) which is caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. This study will collect information and biological specimens from participants who have been tested for the SARS-CoV-2 infection. By doing this study, the investigators hope to learn important new information about SARS-CoV-2 infections and the potentially severe outcomes of COVID-19 to find better ways to manage and treat it in the future. The investigators also hope to learn what makes some people more susceptible to infection to help better inform Veterans on how to reduce their risk of infection. This study also involves the development and maintenance of a participant registry, a data repository, and a biorepository for future research.
