A British nurse has Ebola and is in the London Hospital. Ms Cafferkey was working in Sierra Leone with the charity Save the Children.
She flew home from Sierra Leone in December and she was not ill when she arrived in the UK. She was checked in Sierra Leone and at Heathrow Airport for signs of Ebola. She was fine until she returned home to Glasgow, Scotland. It can take up to 21 days for a person to show symptoms that they have Ebola.
Ms Cafferkey is the second person to have Ebola in the UK. In September another nurse, William Pooley, was diagnosed with Ebola. He recovered completely within a few days. Professor Hugh Pennington, an expert in Ebola, says that people respond to Ebola in different ways.
Ebola has killed 7,800 people, mainly in West Africa since it broke out one year ago.
