What is it about?
COVID-19 is less deadly now, but long COVID still harms many people. This research found a common gene and blood markers that can predict who is at higher risk, enabling early testing and personal care to prevent severe illness and long-term symptoms.

Why is it important?
Our results suggest that about 10–15% of COVID patients, that harbor a common genetic feature, could benefit from a simple blood test. This test measures specific molecules in the blood and can help doctors make better treatment choices early on.
Perspectives
We are excited to share this clinical tool with the community of COVID patients and doctors, because we see how worried COVID patients are about facing long-term health issue due to COVID, and how important it is for doctors to have the right tools for making the best choices for their patients.
