Another 200 problems have been identified as symptoms of the long-term version of Covid.

For some people, coronavirus can cause symptoms that last weeks or months after the infection has gone.

This is sometimes called post-Covid-19 syndrome or "long Covid".

The problem is continuing to cause serious issues worldwide for many who felt they were in the clear once said to have been recovered.

And now another 200 problems as diverse as hallucinations, inability to yawn or cry and decreased penis or testicle size have been identified as symptoms.

A new study by a team of researchers at University College London (UCL) who have all got or had long Covid themselves suggests long Covid may be causing more symptoms than previously thought.

The UCL study used data from 3,762 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 programme for anyone who thinks they have long Covid.

These are some of the symptoms of long Covid identified in the new study from UCL…


Blood clots, fainting, high or low blood pressure, bulging or inflamed veins, fast heart rate.


Itchiness, brittle or discoloured nails, rashes, peeling skin.
