I'm sure you've heard stories of people who've had Covid-19 but who continue to have symptoms. Unfortunately, we still know very little about Covid-19, the disease caused by the SARS-CoV-2 virus. While most people who suffer from Covid-19 experience symptoms for up to four weeks, there is increasing evidence that some people experience these symptoms much longer. Nature calls this post-acute Covid-19. We call it long Covid or long-haul Covid. These continuing symptoms are likely to include fatigue, difficulty breathing, chest pain, brain fog and joint pain.
You might be tempted to say these symptoms are psychosomatic. But Nature notes that survivors of other coronavirus infections have also suffered from persistent symptoms.
Three studies have been conducted in the U.S., Europe and China.
The US study was a telephone survey of 1,250 patients from 38 hospitals in Michigan. Nearly a third reported persistent symptoms 60 days after discharge.
The most detailed study comes from Wuhan, which conducted an in-person evaluation of 1,733 patients at six months after discharge. Seventy-six per cent were demonstrating at least one symptom. The most common complaint was fatigue or overall weakness.
