Inevitably after events such as earthquakes and tsunamis, there is an immediate response by the aid agencies as relief operations get underway to try and restore basic infrastructure and provide the basic fundamental items that are necessary for survival and subsequent recovery.

The threat of disease increases hugely due to the large numbers of people living close together, often in squalid conditions, and without proper sanitation.
