A Save The Children aid worker was confirmed as having Ebola in Glasgow yesterday, before being moved to London this morning.
The woman, an NHS health worker, was working in Sierra Leone and had taken a flight to Casablanca before landing at Heathrow where her temperature was taken.
It was normal, so she was allowed to carry on to Glasgow, where she became feverish.
She was then put into an isolated ward at a Glasgow hospital, before being flown and taken by ambulance to a specialist unit at a London hospital earlier today.
The risk to the public's health is said to be 'very low'.
With this new outbreak of Ebola in the UK, we give you a round-up of some of the questions you may be looking for answers to.
How do you catch Ebola?
Health experts say that you need to have direct touch with an infected person's bodily fluids such as vomit, diarrhoea or blood and then touch your own body such as your nose or mouth.
Before someone has symptoms, they are not infectious – but it is only when they become very ill with vomiting and diarrhoea that the risk is substantially higher of getting the virus.
If they are only feverish, they do not have much virus in their blood and the risk of passing it on is 'low'.
Can I get it from gym equipment that has an infected person's sweat on it?
Experts have said this is 'not a significant risk', as a person would have to be critically ill to have enough virus in their sweat to possibly infection someone.
What about saliva or sneezes?
Again, the person would have to be bedridden and very ill to spread it this way, and the sneeze would have to be directly on someone else's eyes, nose or mouth.
But it is not a respiratory virus like a cold or flu.
Is it an airborne disease?
No, you cannot get it by breathing in air particles and there is no evidence to suggest that it will become so in the future. You are most likely to get Ebola from caring for a sick person and getting in contact with their bodily fluids.
