A coronavirus "variant of concern" first detected in Brazil has now been found in the UK.
Three cases have been detected in England and separately three in Scotland.
In England, officials are still trying to track down one of those who tested positive for the new variant.
Meanwhile the three Scottish residents had flown to Scotland from Brazil via Paris and London, the Scottish government said.
Experts believe this variant, first detected in travellers to Japan from Manaus in northern Brazil in January, could be more contagious.
In England, the first two cases were from the same household in south Gloucestershire, with a history of travel to Brazil, but the third is not linked, Public Health England (PHE) said.
The whereabouts of that third person are still not known, as PHE says they did not complete their test registration card so follow-up details are unavailable.
Officials are asking anyone who took a test on 12 or 13 February and who has not received a result or has an uncompleted test registration card to come forward immediately.
With regards the three cases in Scotland, the government said other passengers, who were on the same flight from London to Aberdeen, are now being contacted.
