Unveiling the Future: Identifying Markers of Prolonged COVID Symptoms

A recent study published in Nature used blood tests and machine learning to identify potential biological markers associated with long COVID, a collection of persistent symptoms experienced by individuals for more than six weeks after contracting COVID-19. The study found lower levels of cortisol, distinct differences in certain immune cells, and inflammatory markers in the blood of participants with long COVID symptoms. While more research is needed, these findings could help in diagnosing and treating long COVID, providing validation for those affected and potentially qualifying them for necessary services.
