Medical tests have shown a patient treated in isolation at Sweden's Uppsala University Hospital for suspected Ebola is not infected with the virus, local authorities have said.
The man had been in Burundi for about three weeks and had exhibited classic symptoms of haemorrhagic fever, including vomiting blood, the hospital's chief medical officer said earlier.
Symptoms of the highly contagious and often deadly virus can take up to three weeks to appear.
There is no known Ebola outbreak in Burundi, but it borders the Democratic Republic of Congo, which has been fighting an outbreak for almost six months.
The disease has killed 356 of the 585 people known to have been infected.
The epidemic in a volatile part of Congo is the second worst ever, according to the World Health Organization.
The largest outbreak was one in 2013-2016 in West Africa, where more than 28,000 cases were confirmed.
The emergency clinic in the Swedish town of Enkoping, where the patient was first admitted, was closed and staff who had been in contact with him were being looked after.
