A hospital patient has the lethal Ebola virus, doctors suspect.
Medics at Skåne University Hospital in Lund, Sweden, are investigating after the patient showed symptoms of the vile fever.
"There are confirmed cases of Ebola in the area where the person has been staying," Maria Josephson, director of operations at the infection clinic, said.
The person, whose age, gender or other details have not been identified, visited the clinic on Monday.
But they quickly fell ill with a high temperature and other feverish symptoms.
They are now waiting for test results.
The Ebola virus disease - previously called Ebola haemorrhagic fever - is a viral infection that occurs in humans and primates.
It was first detected in regions close to the River Ebola in the Democratic Republic of Congo, which gave the disease its name.
To date, scientists have identified five strains of Ebola - four of which are known to cause disease in humans.
In June, a five-year-old died after the world's "second biggest outbreak" reached Uganda.
Reports say the boy had travelled across the border with his mother and father on Sunday.
His mother had returned to Congo to nurse her father, who died of the disease, the health minister Jane Aceng said at the time.
More than 2,000 people have died in the latest outbreak over the last 10 months - making it the second biggest in history.
Most people who contract the disease will die from their symptoms with a terrifying 67% fatality rate being reported.
