(CNN) -- A nurse in Nigeria. A businessman in Saudi Arabia. A Spanish priest in Liberia.
With the World Health Organization announcing Wednesday that 932 deaths had been reported or confirmed as a result of Ebola hemorrhagic fever, Saudi Arabia joined the list of countries with suspected cases.
"This is the biggest and most complex Ebola outbreak in history," Dr. Tom Frieden, director of the U.S. Centers for Disease Control and Prevention, said.
Nearly all of those deaths have been in Liberia, Sierra Leone and Guinea, where more than 1,700 cases have been reported, according to WHO. The agency said 108 new cases were reported between Saturday and Monday in those countries and Nigeria.
Liberian President Ellen Johnson Sirleaf has declared a state of emergency for 90 days because of the deadly outbreak, her office announced Wednesday.
