A woman tested for Ebola at the Royal Cornwall Hospital in Truro is expected to be discharged later today after doctors gave her the all-clear.
She had been kept in isolation at the hospital in Treliske, awaiting test results.
She was one of three woman who had recently returned from a country affected by Ebola, showing suspected symptoms of the disease.
A Scottish female patient became unwell after working to assist people in an area plagued by the outbreak.
The woman was expected to arrive at Aberdeen Royal hospital for tests and has been described by health workers as "low risk".
Meanwhile, questions have been raised over screening at UK airports after it emerged Ebola patient Pauline Cafferkey had her temperature checked seven times at Heathrow Airport before boarding a flight from London to Glasgow earlier this week.
The 39-year-old, who was allowed to travel on the British Airways flight on Sunday night, is now being kept in isolation at the Royal Free Hospital in north London.
Health officials are now desperately trying to trace up to 100 passengers who were on flight BA 1478 with Cafferkey.
Consultant psychiatrist Martin Deahl, who sat next to Cafferkey on the flight to Heathrow, described the screening at the airport as "chaotic".
"We got to Heathrow, off the plane just like any other passenger, and then got to UK Border Agency staff who checked the passports," he told the Telegraph.
"At that point we were identified as having come from Sierra Leone and escorted by a Border Agency officer to a suite of rooms just off that arrivals hall and where we waited to have our so-called health check."
