Scots have been diagnosed with Zika virus which has caused a health emergency across South America.
The Scottish Government stressed the disease “does not pose a public health risk” – but said an unknown number of cases had been identified.
Fear of infection has led a number of competitors to opt out of this year’s Olympic Games in Brazil, including top British golfer Rory McIlroy.
The Zika virus is associated with a birth defect called microcephaly, which results in children being born with abnormally small heads and brain damage.
More than 50 people across the UK have been treated after contracting the condition, which the NHS said in most cases “is a very mild infection and isn’t harmful”.
The virus is spread by a type of mosquito not found in the UK and it cannot be caught through person-to-person or airborne contact.
But experts have also warned that the disease can be transmitted sexually.
A Scottish Government spokesman said: “We can assure the public that Zika does not pose a public health risk in Scotland, and of the cases identified in the UK a very small number have been found in Scotland.
“The mosquito that spreads the virus is not found in the UK, and in any case would not be able to establish in Scotland because of our climate. Zika cannot be spread through person-to-person or airborne contact.”
He added: “We have already informed the at-risk groups about the risks and how to protect themselves through Health Protection Scotland’s travel advice.
“We continue to closely monitor developments in our understanding of the Zika virus as treatments and testing regimes develop.”
Since the Zika epidemic began in 2015, nearly 5,000 cases of microcephaly have been recorded in affected regions.
On February 1 the World Health Organisation declared the epidemic an international public health emergency.
Worldwide concern has centred on north-east Brazil but more than 20 other countries have now been affected. Pregnant women have been advised to avoid non-essential travel to disease hotspots.
So far more than 1,650 Zika infections have been reported in the US – four patients in Florida who have tested positive for the virus appear to be the first cases not linked to travel outside the US mainland.
