WHO technical notes on drinking-water, sanitation and hygiene in emergencies

WHO prepared these notes to assist those working immediately or shortly after an emergency to plan appropriate responses to the urgent and medium-term water and sanitation needs of affected populations.The notes are relevant to a wide range or emergency situations, including both natural and conflict-induced disasters. They are suitable for field technicians, engineers and hygiene promotors, as well as staff from agency headquarters. The English version of the Notes can be downloaded from the WHO web site.


Guidelines for Temporary Shelter

This Basic Guide enables professionals and experts working in different health areas to address, in a timely manner, the needs inherent to caring for a displaced or refugee population during a crisis. The Basic Guide is designed as a set of questions to give an idea of the appropriate actions or response principles required for these situations.


Sanitary Guidelines for Camps and Settlements

"Sanitation" is defined in this guide as all activities involved in proper water supply management and excreta and solid waste disposal.

Mounting a sanitation system in shelters and camps must not only involve the use of simple engineering techniques but consider social and cultural factors at the site of the intervention as well as the costs.


Rodents in Disasters

Rodents are mammals of the order Rodentia, with rats and mice belonging to the suborder Myomorpha. Members of the Muridae family are the dominant species in every region of the world, due to their ability to adapt to and exploit new situations. Commensal rats and mice, that is those that live at the expense of humans, invade their dwellings, eat their food, upset their comfort, and frequently transmit diseases to them, belong to this family. Three species of commensal rodents are the most widely distributed: the Norwegian rat, Rattus norvegicus; the roof rat, Rattus rattus; and the common mouse, Mus musculus.
