A Nigerian woman who arrived in Abu Dhabi on a transit flight and who may have been infected with the Ebola virus has died, health officials in the United Arab Emirates said.
A statement carried by the state news agency WAM said the 35-year-old was travelling from Nigeria to India for treatment of advanced metastatic cancer.
Her health deteriorated while in transit at Abu Dhabi's main airport and, as medics were trying to resuscitate her, they found signs that suggested a possible Ebola virus infection.
The woman's husband and the five medics who treated her are being isolated pending test results.
An Ebola outbreak has killed more than 1,100 people, mostly in the three West African countries of Guinea, Liberia and Sierra Leone, according to WHO figures. Four people have died after contracting the disease in Nigeria, Africa's most populous country.
The Ebola virus is typically transmitted through direct person-to-person contact or through contact with bodily secretions from an infected person. The WHO considers the risk to passengers travelling on a flight with an infected person to be "very low".
Abu Dhabi is the capital and largest of seven sheikdoms that make up the United Arab Emirates. The country has grown into a major long-haul aviation hub. It is home to Dubai-based Emirates, the Middle East's largest airline, and Abu Dhabi-based Etihad Airways.
Emirates earlier this month became the first carrier to halt flights to Guinea because of concerns about the spread of the Ebola virus there.
