In countries with poorly developed infrastructure and few health resources, the effects of natural or man-made disasters on persons with disabilities are particularly devastating. Although foreign aid may be forthcoming, it is often short-lived, whereas disabilities and many other consequences are long-term problems. In countries where rehabilitation facilities are inadequate, a sudden increase in the number of persons with newly acquired disabilities creates overwhelming pressures on the health and social sectors. Rehabilitation programmes therefore need to be started as soon as possible, although this is rarely achieved because of inadequate rehabilitation facilities.
