A number of people in Scotland have been diagnosed as having the Zika virus, but the government there stressed that it "does not pose a public health risk".
The Scottish government said that an undisclosed number of cases had been found.
More than 50 people across the UK have been treated for the infection, which is associated with a birth defect called microcephaly.
Microcephaly results in children being born with abnormally small heads and brain damage.
The Zika virus has sparked a major health alert in South America and fear of the virus has led a number of competitors to opt out of this year's Olympic Games in Brazil.
While pregnant women are being advised to postpone non-essential travel to disease hotspots, the NHS stressed that for "most people it is a very mild infection and isn't harmful".
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."
Since the Zika epidemic began in 2015, nearly 5,000 cases of microcephaly have been recorded in affected regions.
On 1 February this year the World Health Organisation declared the epidemic an international public health emergency.
Worldwide concern has centred on northeast Brazil but more than 20 other countries have now been affected.
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.
Florida yesterday began aerial spraying to kill mosquitoes in a Miami neighborhood with the first US spread of the Zika virus.
Miami-Dade County authorities sprayed droplets of an insecticide called Naled, marking their first aerial mission since local transmission of Zika was confirmed in an area of about a square mile around the Wynwood arts district near downtown Miami.
The impact immediately appeared to be more successful than earlier mosquito control techniques, said Dr Tom Frieden, director of the US Centers for Disease Control and Prevention.
"They had very high kill rates in the mosquito traps there," he said at a news conference.
He explained that the aerial spraying inserts insecticides into places that cannot be reached by fogging trucks or ground crew spraying chemicals from backpack units.
Authorities sought to quell any concerns about safety from the chemical when sprayed appropriately, noting Naled has long been used in controlling mosquitoes in Miami-Dade County and around Florida.
Florida health authorities have identified 15 Zika cases spread by local mosquitoes and expect there may be more.
