Ten people linked to Kenya's first-ever Ebola case quarantined as screening concerns grow
Those placed at the Ebola isolation facility are under constant observation
Ten people who came into contact with a man who died of Ebola in Kenya have been quarantined, health officials in the East African nation say.
They are also trying to trace 57 other contacts of the Kenyan patient after he travelled from the Democratic Republic of Congo, dying in hospital in Nairobi on Monday.
This is the East African nation's first-ever Ebola case and there is now growing concern about the country's screening measures.
The Africa Centres for Disease Control and Prevention chief has told the BBC that despite being sick for a month, the patient passed through multiple cities in DR Congo, driving to Uganda and eventually flying to Kenya without his sickness being detected.
"We know that he left Buta, a city in [northern] DR Congo, to drive to Kisangani. And from Kisangani, he took a flight to Beni. From Beni, he drove to Uganda. And from Uganda, he took a flight to Nairobi," Jean Kaseya told the BBC's Focus on Africa programme.
"What are symptoms he was presenting? Why was he not detected?" he asked.
The Ebola virus spreads through contact with infected bodily fluids such as blood or vomit.
The current outbreak in DR Congo, which began in May, has been caused by the Bundibugyo species of Ebola, which is relatively rare, with no approved vaccine or treatment - though trials are under way.
Kaseya said the Africa CDC was investigating the case, alongside the Congolese authorities. A team from the organisation was also due to meet the Kenyan health authorities.
