The World Health Organization warned Tuesday that the agency now expects tens of thousands of people will be infected with the Ebola virus before the current epidemic is contained, and it called for nations to commit far more resources to combating the outbreak, which is ravaging the poor African nations of Liberia, Sierra Leone and Guinea.
The dire new prediction came as the United States pledged to send 3,000 American service members to West Africa to lead the response to the crisis. The U.S. troops will help build new treatment centers in Liberia, where sick patients have been turned away from crowded facilities, and train as many as 500 new health care workers a week to help meet a shortage of volunteers.
Still, U.N. officials said they see no end to the crisis, which is growing at a rate they hadn’t foreseen just two weeks ago.
Bruce Aylward, WHO’s assistant director, said the U.N. agency’s prediction then that 20,000 people would be sickened now appears woefully optimistic. That’s a frightening prospect for a disease that currently is claiming the lives of nearly 50 percent of those who fall ill.
“This health crisis we face is unparalleled in modern times. The gravity of the situation is difficult to get across with just a few numbers,” said Aylward, a Canadian physician and epidemiologist. With the number of cases, 4,985, and deaths, 2,461, doubling in the past 14 days, “you start to get a sense of the rapid escalation we’re seeing of the virus from what was a linear increase in cases to now an almost exponential increase,” he said.
“The reality here is we don’t know where the numbers are going on this,” he said. “When I said we needed a capacity to manage 20,000 cases, that seemed like a lot. That does not seem like a lot today.”
On Tuesday, President Barack Obama announced the new U.S. efforts during a visit to the Centers for Disease Control and Prevention in Atlanta. He said the U.S. mission would include a U.S.-led command center in Monrovia, Liberia’s capital, and 17 new Ebola treatment centers, each able to treat as many as 100 patients.
Obama called the effort the largest medical mission the United States had ever launched and said that while the chance of an Ebola outbreak in the United States is extremely low, the West Africa outbreak was a global problem that would threaten U.S. strategic interests if the economies of the countries affected by the epidemic collapse.
“The scenes we are witnessing in Liberia are gut wrenching,” Obama said. “The world has a responsibility to act, to step up and to do more. The United States of America intends to do more.”
