The Long-term Impact of Infection with Novel Coronavirus (LIINC) study is a collaborative research effort led by the University of California. It aims to understand the long-term effects of COVID-19 on immunity and different organ systems by studying recovered patients.

Adults (18 years+) who have tested positive for COVID-19 (SARS-CoV-2) and are able to attend in-person visits 3-4 times per year at our research center on the San Francisco General Hospital campus are eligible to participate.

Interested individuals will undergo a phone screen, and if eligible, will attend a screening visit to sign consent forms and participate in the Baseline Visit, which includes a detailed questionnaire, a blood draw, and saliva collection. Follow-up visits occur every 4 months and involve a brief questionnaire and a blood test.

Participants will receive $50 for completing the Baseline Visit and $25 for each follow-up visit.

After the initial Baseline Visit, participants are expected to visit the research center every 4 months for follow-up assessments.

During each follow-up visit, participants will complete a brief questionnaire and undergo a blood test to help researchers assess the ongoing effects of COVID-19 on their health.

The study is planned to continue for two years, during which participants may be asked to attend several follow-up visits to track changes in their health post-recovery.
