electing the appropriate control chemical and the means of application, together with advice on planning an implementation programme.

This work is intended to help development workers and planners to identify and assess the risks of vector-borne diseases in a camp and to plan and implement cost-effective ways of controlling them. The main vector-borne diseases are described, the importance of identifying the particular disease, and of considering methods of control is emphasized.

This publication is intended to contribute to prevention and control of the morbidity and mortality associated with dengue and to serve as an authoritative reference source for health workers and researchers. These guidelines are not intended to replace national guidelines but to assist in the development of national or regional guidelines. They are expected to remain valid for five years (until 2014), although developments in research could change their validity.--Publisher's description.

This field manual is intended to help health professionals and public health coordinators working in emergency situations prevent, detect and control the major communicable diseases encountered by affected populations. The manual is the result of collaboration among a number of WHO departments and several external partner agencies in reviewing existing guidelines on communicable disease control and adapting them to emergency situations. The manual deals with the fundamental principles of communicable disease control in emergencies, which are: Rapid assessment to identify the communicable disease threats faced by the emergency-affected population, including those with epidemic potential, and define the health status of the population by conducting a rapid assessment; Prevention to prevent communicable disease by maintaining a healthy physical environment and good general living conditions; Surveillance to set up or strengthen disease surveillance system with an early warning mechanism to ensure the early reporting of cases to monitor disease trends, and to facilitate prompt detection and response to outbreaks; outbreak control to ensure outbreaks are rapidly detected and controlled through adequate preparedness (i.e. stockpiles, standard treatment protocols and staff training) and rapid response (i.e.confirmation, investigation and implementation of control measures); and disease management to diagnose and treat cases promptly with trained staff using effective treatment and standard protocols at all health facilities.

In response to the call of the 48th World Health Assembly for a substantial revision of the International Health Regulations, this new edition of the Regulations will enter into force on June 15, 2007. The purpose and scope of the Regulations are "to prevent, protect against, control and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, and which avoid unnecessary interference with international traffic and trade." The Regulations also cover certificates applicable to international travel and transport, and requirements for international ports, airports and ground crossings.
