Air passengers arriving at Heathrow Airport from Africa are being transferred to Northwick Park Hospital if they show early signs of Ebola.
Anyone who needs to be placed under observation or require further tests will be treated at the medical centre in Watford Road, Sudbury.
However passengers who are deemed to be high risk or show definite traits of the potentially fatal virus will be sent to The Royal Free Hospital.
The hospital in Hampstead is the only one in the country which has two beds dedicated to treating Ebola victims.
Tina Benson, director of operations at Northwick Park Hospital, said: “Patients screened at Heathrow Airport who require further tests and observation are transferred to Northwick Park Hospital.
“There is not a walk-in service at the hospital, patients who are worried about symptoms should call NHS 111.”
British nurse Pauline Cafferkey is currently being treated at The Royal Free after she contracted the disease while volunteering in Sierra Leone.
She is in a critical condition.
