I don't think West Africa lacks bed linen or plastic sheeting, mg. The entire region is, however, pitifully short of sound infrastructure (e.g., roads for transport trucks to roll on) and competent, credible public authorities with the influence and resources rquired to do what's needful.

Sending stuff (that isn't requested drugs and other medical supplies) to the epidemic zone just results in stacks of goods lying around in port cities. The Red Cross usually asks for money -- lots of it -- so the people on the ground can buy from local sources.
