The number of Ebola cases in Africa has surpassed 1,800 cases, according to the World Health Organization.
More than 900 of those patients have died.
A top WHO official says there are ways to stop the virus.
Dr. Keiji Fukuda, assistant director general for health security at the WHO, says international authorities need to raise their response to the crisis.
He also blames the spread on weak health facilities in the underdeveloped nations.
A WHO panel will discuss today on the ethics of using experimental drugs on patients.
Ebola has no cure, but an experimental serum was given to two Americans early last week.
Both patients gave consent to receive the drug, ZMapp, which has never been tested in humans before.
Their conditions are reportedly improving.
Medical ethicists, scientific experts and others affected by the outbreak will discuss the use of unlicensed medicines during the WHO teleconference Monday.
Ebola cases have now been found in Guinea, Sierra Leone, Liberia and Nigeria.
On Sunday, Ivory Coast banned flights to and from those countries affected by Ebola.
Emirates this month became the first major international airline to suspend flights from Guinea.
British Airways stopped its flights to Sierra Leone and Liberia last Tuesday.
