The Royal Cornwall Hospital has told ITV West Country that the patient being tested for Ebola at the hospital had been in West Africa.
It is understood that the patient - who is NOT a health care worker - recently returned from a country affected by an outbreak of the virus. They were placed in the hospital's isolation ward last night.
The results of tests are not expected for at least 24 hours but the hospital says it's just one of a number of checks being carried out.
