International Health Regulations (IHR)
The International Health Regulations are an international legal instrument that covers measures for preventing the transnational spread of infectious diseases. The newly adopted IHR (2005) has as purpose and scope “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”. This page provides a detailed description and information on progress of its implementation, plus relevant links.(24/Jun/2008)

Manual for Indoor Residual Spraying: Application of Residual Sprays for Vector Control (3rd ed.)
The objective of this handbook is to ensure the safe and correct application of a residual insecticide to indoor surfaces on which vectors may rest. Indoor residual spraying is extensively used, especially for malaria and Chagas disease vector control. However, vector control programmes frequently lack well-trained field staff to apply the insecticides and to maintain the application equipment. With good skills and quality application equipment, hazards to human health and the environment, as well as financial losses, can be avoided. It can be used as a model to develop training materials in the countries.(31/Dec/2006)

Public Health Pesticide Management Practices by WHO Member States: Report of a Survey, 2003–2004
Survey objectives were to study key features of public health pesticide management practices by WHO Member States; assist national and international organizations in developing activities to address weaknesses in their management practices; and serve as a baseline for monitoring progress in such activities. In the Americas, 14 countries responded comprising 55% of the at-risk population for major vector-borne diseases: Bolivia, Brazil, Chile, Costa Rica, Cuba, Ecuador, El Salvador, Guatemala, Guyana, Panama, Paraguay. The Caribbean Epidemiology Centre / CAREC assisted with data collection and validation.(31/May/2005)

Safety of Pyrethroids for Public Health Use
Pyrethroids are widely used in public health because of their relative safety for humans, high insecticidal potency at low dosages and rapid knock-down effects. WHO has assessed the safety and efficacy of pyrethroids for different applications in vector control, as well as in disinsection of aircrafts. The purpose of this document is to critically review current knowledge on the safety of pyrethroids and whether existing WHO recommendations for pyrethroid applications should be revised or modified. (This review does not consider the use of pyrethroids in space spraying and vapour applications, e.g. in mosquito coils and aerosols.)(31/May/2005)
