The United Nations secretary general, Ban Ki-moon, plans to visit the three West African countries that have been hit the hardest by the Ebola outbreak, according to a senior United Nations official.
Mr. Ban is to make the announcement at a year-end news conference on Wednesday. The director general of the World Health Organization, Margaret Chan, and his special envoy on Ebola, Dr. David Nabarro, are to accompany him to West Africa.
The trip, which is to begin later this week, seems designed to send a message of solidarity with the three affected countries: Guinea, Liberia and Sierra Leone.
