A nurse newly diagnosed in Dallas with Ebola took a flight from Cleveland the day before she showed symptoms, US health officials have confirmed. The US Centers for Disease Control and Prevention (CDC) is seeking to interview 132 passengers who flew on Frontier flight 1143 on 13 October.

The nurse, the second to contract the disease in the US, reported symptoms of Ebola on 14 October. She had treated a Liberian national who died in Dallas on 8 October.

Thomas Eric Duncan, the first person to be diagnosed in the US with Ebola, started showing symptoms of the disease just days after he arrived in Texas from Liberia, where he contracted the disease.

The two US female nurses known to be infected with Ebola treated him at Texas Health Presbyterian Hospital in Dallas.
