Kenya confirms second Ebola case as relative of country's first victim

Kenya has confirmed a second case of Ebola, 10 days after a businessman died of the virus after he had travelled to the East African nation from the Democratic Republic of Congo.

The new patient, a 39-year-old man, is a close relative of the first case and was already in quarantine when he fell ill on Tuesday, Kenya's health ministry said.

The incubation period for Ebola ranges from two to 21 days, meaning those exposed to the virus may not become ill for several weeks.

Detecting his illness early had improved his chances of recovery and limited the chance of him passing the virus on to others, the ministry said, as it urged the public to "stay calm but vigilant".

"Both cases are linked, and there is no evidence of spread in the wider community," the ministry added.
