What this research studies

Many people experience lingering health issues after a COVID-19 infection, often called Long COVID or PASC. This project uses health information from seven hospital systems across the U.S. to learn more about these long-lasting symptoms. We want to identify different patterns of symptoms that appear over time and understand what causes them. The goal is to create models that can help predict which patients might develop Long COVID and how their condition might change.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals who have experienced COVID-19 infection and are now dealing with persistent symptoms, often referred to as Long COVID or PASC.

Not a fit: Patients who have not had COVID-19 or are not experiencing lingering symptoms after their acute infection would not directly benefit from this particular research.

Why it matters

Potential benefit: If successful, this work could help doctors better identify, understand, and eventually treat patients suffering from Long COVID by predicting who is at risk and how their symptoms might evolve.

How similar studies have performed: While the understanding of Long COVID is still developing, this approach of using large-scale electronic health records to identify symptom patterns has shown promise in other complex conditions.
