Health officials are investigating whether Ebola patients in Nigeria and Kenya may have crossed paths at Uganda's Entebbe International Airport earlier this month, reports citing the Africa Centres for Disease Control and Prevention (Africa CDC) said on Thursday.

Both patients travelled through Entebbe on 3 October, and investigators are examining whether they could have been exposed through shared equipment or other contact, Africa CDC head of emergency preparedness and response Dr Wessam Mankoula said, stressing this was one possible scenario and no link had been established.

Nigeria is battling its first Ebola case in more than a decade, while Kenya has confirmed nine infections, including one death, according to the reports. The Nigerian patient, a 42-year-old Ugandan-born woman who lives in Abuja, is receiving treatment in isolation and is showing signs of improvement, the World Health Organization said, according to the reports.

The Kenyan man had travelled from the Democratic Republic of Congo through Uganda before arriving in Nairobi on 3 October, the reports said. He later died, becoming Kenya's first recorded Ebola death in the current outbreak.

Nigeria's Centre for Disease Control and Prevention is conducting genomic sequencing to help establish whether the infection is linked to other cases, and WHO officials said the Nigerian patient's source of exposure is still not known and her travel history is still being pieced together.
