A coronavirus mutation that originated in Spanish farm workers has spread rapidly through Europe and now accounts for most UK cases, a new study suggests.
The variant, called 20A.EU1, is known to have spread from farm workers to local populations in Spain in June and July.
People returning from holidays in Spain over the summer are believed to have played a key role in spreading the strain across Europe.
The study found that in Wales and Scotland the variant accounted for around 80% of cases in mid-September, whereas frequencies in England were around 50% at that time.

Seems that international travel has had a major influence on covid rates. Not unreasonable to ask if anything in the people/processes involved encourages super-spreader events.
