DAKAR, Senegal — Médecins Sans Frontières/Doctors Without Borders (MSF) says it has pulled out of Lofa County in Liberia where there have been no reported Ebola cases in the past six weeks.

Lofa, on the border with Sierra Leone and Guinea, was once a hot spot of Ebola and the medical group said Thursday that when it took over a treatment unit there in August up to 130 people were turning up each day. On Wednesday, the World Health Organization said the area has not recorded a case for six straight weeks.

MSF said Thursday that it has either completed or handed over all projects in Lofa to the Health Ministry or other aid groups. Its treatment centre is closed but another group will reopen it as a care centre.
