The woman in south-west Kenya who is being tested for Ebola went to hospital with a fever, headache, joint pains, sore throat and she was vomiting.
She had been treated for malaria in a smaller hospital but her condition was getting worse.
She was re-tested for malaria and the results were negative. It's at that point that the health workers referred her to the Kericho County Referral Hospital, which has an isolation unit.
She later developed diarrhoea but I'm told her condition is now improving.
The private clinic referred her "out of caution" since she had travelled to the border with Uganda.
But it's important to note that the area she visited was in the east of Uganda. The outbreak that was confirmed last week was in the west of the country, bordering the Democratic Republic of Congo.
Her blood samples have been taken to Nairobi to be tested for Ebola.
