CDC Director Frieden testifies on ebola outbreak
Frieden said that weak systems of healthcare and challenges health workers face in West Africa contributed to the spread of the outbreak.
"The effort to control the outbreak in some places is complicated by fear of the disease and distrust of outsiders," Frieden said. "Security is tenuous and unstable, especially in remote isolated rural areas."
Frieden said that the CDC and its must partners must provide a surge of resources and expertise to help end the outbreak as there is no known cure for the disease. The director said that responding appropriately to active cases and preventing future ones should be the goal of the CDC and others.
Frieden also said that ebola does not pose a significant threat to the U.S. because many factors, including how the disease is transmitted and a difference of customs, mitigate the danger.
Ebola was first detected in 1976 in what is now the Democratic Republic of Congo. The current outbreak in West Africa is the biggest and most complex ever documented.
