A suspected case of Ebola has been reported at a hospital in Sweden.
Staff who have been in contact with the patient are also being looked after, the regional authority said.
Test results are expected on Friday night and officials have stressed that the disease may not be Ebola, and that for now it is “only a matter of suspicion”.
Symptoms of Ebola – including fever and stomach pain – may take three weeks to appear after contact with the deadly virus, which has killed hundreds of people in the Democratic Republic of Congo in recent months.
Of 585 people reported to have been infected there in the last six months, 356 have died.
The epidemic is now surpassed by the outbreak that crippled western Africa between 2013 and 2016, during which more than 28,000 cases were confirmed.
