Sponsor: University of California, San Francisco
Conditions: Long Covid
Countries: United States
The purpose of this study is to better understand the biological changes associated with Long COVID and to identify laboratory tests (biomarkers) that may help diagnose the condition and measure how it changes over time. Researchers will enroll people with Long COVID as well as people who have fully recovered after COVID-19 infection. Participants will provide health information and biological samples, such as blood, saliva, stool, and, for some participants, tissue biopsies. These samples will be used to study the biological processes involved in Long COVID and to support the development of new diagnostic tests that may improve future research, clinical trials, and patient care.
Sex: ALL

Healthy volunteers: Yes
Study type: OBSERVATIONAL
Inclusion Criteria: * Willing and able to provide written informed consent, and * Age \>/= 18 years, and * Either: History of a SARS-CoV-2 infection resulting in Long COVID symptoms, confirmed by the investigator, or Exposure to SARS-CoV-2 without establishment of Long COVID. * Enrolled or willing to enroll and complete at least 1 visit in the UCSF Long-term Impact of Infection with Novel Coronavirus (LIINC). * Enrolled or willing to be referred for a gut biopsy procedure under related IRB-approved protocols. Exclusion Criteria: * Self-reported or documented chronic anemia with hemoglobin \< 9 g/dL. Anemia during a preceding acute illness will not be exclusionary. * Serious medical or psychiatric illness that, in the opinion of the site investigator, would interfere with the ability to adhere to study requirements or to give informed consent. * Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data.
