Sweden - UN Secretary General Ban Ki-moon said he will leave Wednesday for a visit to Ebola-hit countries to take stock of international efforts to beat back the deadly epidemic.
"I want to see the response for myself and show solidarity for those affected," Ban told a news conference at UN headquarters.
Ban will travel to Guinea, Liberia, Sierra Leone and Mali, where the United Nations is leading the response to the health crisis. He will also go to Ghana, where the UN Ebola mission is headquartered.
The visit comes a year after the outbreak began in Guinea and follows sharp criticism from non-governmental organizations that UN agencies like the World Health Organization were too slow to respond.

Ban has said that more aid is needed to fight Ebola but declared that the outbreak could be brought under control in 2015 if the international mobilization is kept up.
The UN Security Council has declared the Ebola outbreak a threat to international security and peace, and US Ambassador Samantha Power paid a visit to West Africa in October.
More than 6,800 people have died from the Ebola virus, almost all of them in West Africa, and there have been close to 18,500 cases of infection.
