A man who became the second confirmed Ebola case in the Congolese city of Goma has died, an official said on Wednesday.

The city of more than two million people had its first confirmed case earlier this month, with the second-deadliest Ebola outbreak in history declared a rare global health emergency days after the first Goma case was announced.

The Ebola response coordinator, Jean-Jacques Muyembe, who confirmed the death on Wednesday morning, a day after the case was announced, said there appeared to be no link between the case and the previous one in Goma announced two and a half weeks ago.

The man arrived in Goma on July 13 from a mining area in northeastern Ituri Province, but it was not clear what he did after he started showing symptoms on July 22, officials said. He was isolated at an Ebola treatment center on Tuesday.
