Senegal has become the latest country to seal its border with a west African neighbour to ward off the deadly Ebola virus, as the new UN pointman on the epidemic said preparations must be made for a possible flare-up of the disease.
Senegal's decision to close its land border with Guinea, announced by the interior ministry on Thursday, is part of intensifying efforts to contain the outbreak that has killed 1,350 people since March in Guinea, Liberia, Nigeria and Sierra Leone.
