Guinea, Liberia and Sierra Leone are battling the Ebola virus, which has killed 932 people in those countries. The epidemic has also spread to Nigeria.
"The possible consequences of further international spread are particularly serious in view of the virulence of the virus, the intensive community and health facility transmission patterns, and the weak health systems in the currently affected and most at-risk countries," the World health Organization said Friday, after two days of emergency meetings.
The United Nations health agency described it as the worst outbreak in the four-decade history of tracking the disease.
"A coordinated international response is deemed essential to stop and reverse the international spread of Ebola," WHO said.
Liberian President Ellen Johnson-Sirleaf said the fast-spreading disease has overwhelmed her nation's health care system.
"The scope and scale of the epidemic ... now exceed the capacity and statutory responsibility of any one government agency or ministry," she said.
She declared a 90-day state of emergency this week, which will allow her government to set up a series of measures to prevent the spread of the disease.
As the nation struggles to contain the epidemic, the United States ordered relatives of its embassy employees to leave Liberia. The U.S. Embassy is in the capital of Monrovia -- one of the areas hardest-hit by the epidemic.
Washington said it's sending experts to Liberia, including 12 specialists from the Centers for Disease Control and Prevention, and a 13-member disaster assistance response team from the United States Agency for International Development.
