A teenager is in isolation at the north’s biggest hospital after contracting meningitis following a massive scouting event in Japan.
The child, whose details have not been released, was among a group of about 30 from the Highlands who went on the trip to the Far East.
They are being treated at Raigmore Hospital in Inverness.
A second child has also been confirmed as having the illness and is understood to be recovering at home.
Both are aged between 14-18 years old and are from troops based in north.
Officials from Health Protection Scotland (HPS) are contacting scouts in the party who travelled to Japan to give them antibiotics in order to prevent the condition being transmitted.
And advice will be sent to all troops in Scotland who attended the event telling them to contact their doctor for advice if any of them become unwell
The Highland teenagers were among 150 Scottish boys and girls and 100 adults who flew to Japan for the 12-day event, which took place in Kirara-hama and was attended by tens of thousands of children from across the globe.
The Highland youngsters returned to Scotland at the weekend.
Last night, one mother of a teenager who was at the event declined to comment about the meningitis scare, although she confirmed her daughter was not affected.
Others said that they had not been told about the outbreak.
One man said that the jamboree was “a fantastic event” and a “great experience” for the children.
A HPS spokesman said: “Health Protection Scotland is aware of two cases of meningococcal disease in the north of Scotland.
“Both cases are scouts who recently travelled to Japan to attend an International Scout Jamboree.
“Both cases attended their local hospitals, were treated and are recovering well.
“All close contacts have been identified and are being prescribed antibiotics and immunisation as a precautionary measure.
A Scouts Scotland spokeswoman said: “We are very sorry to hear that two scouts have fallen ill with cases of meningococcal disease.
“As soon as we were alerted we have been working with Health Protection Scotland and local scouting leaders to ensure that the young people and parents are fully informed and supported.”
Meningitis is a serious but relatively rare illness.
Symptoms can include fever, severe headache, neck stiffness, vomiting, dislike of bright lights and drowsiness.
A skin rash of small red or purple spots may appear suddenly and does not fade when pressed.
The risk of developing the illness after having contact with someone who has contracted it is low.
Close contacts are identified by health protection specialists and offered antibiotics to eliminate the bacteria in case they are carriers.
The jamboree included a visit to Hiroshima Peace Memorial Park and the Peace Museum as part of the 70th anniversary of a nuclear bomb being dropped on the city at the end of World War II.
Other activities included watersports and learning about Japanese culture.
