- Thousands of people in Iceland gave swabs to test for COVID-19
- Researchers sequenced the genome of the virus to look for mutations
- They found 40 which could be traced to three different countries – Austria, Italy and England. Seven people went to a football match in England
- Genetic sequencing allows scientists to trace where the virus has travelled

Scientists in Iceland claim they have found 40 mutations of the coronavirus, which has left the world gripped in fear.
The mutations were discovered by analysing swabs of COVID-19 patients in Iceland, where almost 600 cases have been reported so far.
Using genetic sequencing, the researchers identified how many mutations the virus had accumulated.
These genetic variants can act as the fingerprints of the virus to indicate where in the world it originated.
The Icelandic scientists were able to trace the coronavirus back to three European countries – Austria, Italy – the epicentre of the outbreak – and England.
Seven infected people all went to the same, undisclosed football match in England, the team claim.
