The World Health Organisation says a new, highly contagious strain of coronavirus is no more likely to cause complications.
The strain is sweeping across southern England, prompting a number of European countries to cut off travel with the UK.
It has been detected in other nations, including in Australia’s hotel quarantine system.
W-H-O director general Tedros Adhanom Ghebreyesus says they are monitoring the situation.
“The UK has reported that this new variant transmits more easily, but there is no evidence so far that it’s more likely to cause severe diseases or mortality. The WHO is working with scientists to understand how these genetic changes affect how the virus behaves”, said Mr Ghebreyesus.
The public has been urged not to become complacent.
