A doctor who contracted the deadly disease of Ebola in Sierra Leone has died at the Nebraska Medical Center in the United States, the hospital said Monday.

Martin Salia, a native of Sierra Leone and a U.S. legal permanent resident, has passed away as a result of advanced symptoms of the disease, the hospital said in a statement.

"It is with an extremely heavy heart that we share this news," Phil Smith, medical director of the Biocontainment Unit at the Nebraska Medical Center said.

"Dr. Salia was extremely critical when he arrived here, and unfortunately, despite our best efforts, we weren't able to save him."

Salia was suffering from advanced symptoms of Ebola when he arrived at the hospital Saturday, which included kidney and respiratory failure, the hospital said.

He was placed on dialysis, a ventilator and multiple medications to support his organ systems in an effort to help his body fight the disease.

He also received a dose of convalescent plasma and ZMapp therapy was initiated on Saturday.
