"New Study Identifies 12 Key Symptoms Defining Long COVID"

A study by the National Institutes of Health (NIH) found that about 10% of people experience long COVID after an Omicron infection, a lower estimate than earlier in the pandemic. The study identified a dozen symptoms that most distinguish long COVID, including fatigue, brain fog, and heart palpitations. The researchers assigned scores to the symptoms to establish a threshold that could help ensure similar patients are enrolled in studies of possible long COVID treatments. However, doctors shouldn't use the list to diagnose someone with long COVID, as patients may have other symptoms not on the list.
