The earthquake that struck the central coast of Peru on 15 August 2007 was a disaster that mobilized international humanitarian assistance to address the needs of the affected people in the regions of Huancavelica, Ica, and Lima. It also was an opportunity to prove the effectiveness of regulations and procedures to facilitate the entry and distribution of donations and medical goods during a major emergency. In the first month after the earthquake, the national government approved new regulations that aimed to reduce waiting time while reducing the number of requisites required by customs. More than 5,500 tons of international donations arrived in Peru in a short period of time. Many donated medicines arrived unsorted, without an international non-proprietary (generic) name on the label, and some medicines did not have any relationship with the diseases that would appear in the aftermath of the event.
