Possible symptoms of long COVID

A persistent dry cough and loss of taste and smell are two of the most common symptoms associated with COVID-19, but now another 200 problems as diverse as hallucinations, inability to yawn or cry and decreased penis or testicle size have been identified as symptoms of the long-term version of the virus, dubbed long COVID.

A study by a team of researchers at University College London (UCL), who all have or had long COVID themselves suggests it may be causing more symptoms than previously thought. The study’s first author, Hannah Davis, explains: “The entire team is made up of long COVID patients, which is what makes us unique and allowed us to identify even the less publicly known symptoms that long COVID patients experience.

“Most people don’t realise how multi-systemic long COVID symptoms are, and how most patients experience dozens of symptoms across multiple organ systems.”

Ms Davis, who’s had bad cognitive dysfunction, memory loss, and postural tachycardia (super-high heart rate after standing) as a result of long COVID, says there’s currently no biomarker (a molecule that confirms the presence of a particular virus or disease) for the condition.

But until one is found, she stresses: “Long COVID is actually surprisingly recognisable given the large number of new symptoms patients experience, the multi-systemic nature of these symptoms, and the recognisable symptoms – such as post-exertional malaise – that aren’t common in other illnesses.”

The UCL study used data from 3762 people from 56 countries and identified 203 long COVID symptoms in 10 organ systems. It found the most common symptoms were fatigue, post-exertional malaise (the worsening of symptoms after physical or mental exertion), and cognitive dysfunction (brain fog). The authors are now calling for a national screening program for anyone who thinks they have long COVID.

And while this study did not estimate how common the condition is overall, Imperial College London’s React-2 study published in June suggested more than two million people in England may have had long COVID, with about a third of people who had coronavirus reporting symptoms lasting at least 12 weeks. The most common persistent symptoms flagged in that study included tiredness, shortness of breath, muscle aches and difficulty sleeping.
