A new report released today claims there were at least 12 different strains of coronavirus spreading through the UK in March.
The UK government-funded study came to that conclusion after genetic scientists analysed the DNA of the killer virus in 260 infected people from all over the UK.
Their research discovered 12 unique lines of the killer bug, one of which has only ever been found in Britain suggesting it mutated on UK soil.
But the Covid-19 Genomics UK Consortium (COG-UK) said the 'substantially higher' number of strains identified could be a result of under-sampling in the UK, Mail Online reports.
