Most people who contract SARs-COV-2 virus are either asymptomatic or experience mild to moderate illness. The symptoms tend to subside within 2–3 weeks after symptom onset. However, some people, even after testing negative for the virus, continue experiencing lingering symptoms for over 4 weeks and beyond.
Keeping all of these in mind, the Therapies for long COVID (TLC) study group, at the University of Birmingham in the United Kingdom, has come up with certain predictors of long COVID.
The study group looked into 27 previously published studies on long COVID to find out about the most common symptoms and also to learn about some possible indicators of long-term risks.
The team of researchers found that fatigue, difficulty breathing, muscle pain, joint pain, headaches, and altered sense of smell and taste were among the most prevalent symptoms during the illness. Apart from that, they also learnt that patients dealt with sleep disorders and cognitive problems like inability to focus, issues with memories, etc.
