Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals who have tested positive for COVID-19 or other respiratory viruses and have either recovered or may have been exposed to COVID-19.

Probably not a fit

Patients under 6 months old or those with severe anemia or low platelet counts may not benefit from this study.

What this trial studies

This observational study aims to collect SARS-CoV-2 secretions and serum from patients to understand the natural history of COVID-19 infections and characterize post-COVID morbidity. It focuses on analyzing immune responses, virus genome sequencing, cytokine responses, and virus shedding in both acutely infected and convalescent patients. The study will establish a data registry to track viral sequences and clinical courses, helping to identify predictors of severe outcomes and optimize treatment strategies for high-risk populations.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies and better management of COVID-19 and its long-term effects.

How similar studies have gone: Other studies have shown success in characterizing immune responses and viral shedding in COVID-19, making this approach both relevant and potentially impactful.
