Health officials are telling Capital a woman from Cardiff - who may have been exposed to Ebola - has been given the "all clear"
The woman put herself into voluntary self isolation after she came back from a trip to Western Africa three weeks ago.
The maximum incubation period for the Ebola virus is 21 days - that's now passed and she is no longer at risk.
What is Ebola? Ebola is a life-threatening virus.
You can get it from coming into contact with animals or other people's blood that is infected.
It then can lead to internal and external bleeding along with vomiting and diarrhoea.
It's reported that out of every ten people on average five to nine die.
The virus has killed hundreds in Liberia, Sierra Leone, Nigeria and Guinea.
Public Health Wales are keen to point out there is no cases of Ebola in Wales at the moment.
But their officials are on alert because of the outbreak in Sierra Leone, Liberia and Guinea.
They say they're remaining vigilant to any unexplained illness in people who have travelled from the area.
It was thought a man from Donegal in Ireland may have died from Ebola.
The 43 year old father of one was found dead after recently coming back from West Africa.
Tests have now been carried out which show he didn't have the virus.
