MONROVIA, Liberia (AP) — A new case of Ebola has been confirmed in Liberia, the World Health Organization said Friday, a setback for the country which had been declared free from Ebola transmissions in January.

Health authorities at the Redemption Hospital in the densely-populated New Kru Town suburbs of Monrovia said a 30-year-old woman died of Ebola.

The woman died Thursday night, said the head of Liberia’s Ebola response, Tolbert Nyenswah.

“She died on arrival and a swab was taken, analyzed in the lab and was confirmed,” Nyenswah said. “We are investigating the source.”
