Answers
Explanation:
The purpose of this document is to provide infection control guidance to help prevent the transmission
of acute infectious respiratory diseases during health care, with emphasis on acute respiratory diseases
that may constitute a public health emergency of international concern as defined in the International
Health Regulations (2005; Annex 1). Managers of health-care facilities may also consider using this
guidance to assist them in preparation for epidemics and pandemics.
This document is intended to be used by government planners, health-care facility administrators,
infection control professionals, occupational health specialists, other professionals involved in patient
care and direct care providers.
The infection control advice provided in the guidelines is based on available information on the main
routes of transmission of pathogens, and is intended to provide guidance for continuous and
sustainable improvement in safety of health care. These guidelines are designed to offer Member
States a conceptual framework for individual adaptation according to local regulations, settings, needs
and resources. Health-care facilities are encouraged to review the recommendations and to adapt them
accordingly.
The guidelines were developed after performing a systematic review of the scientific literature (in
English) identified through PubMed (US National Library of Medicine) and the Cochrane Library,
and secondary papers (in English, and also in Chinese, French, Portuguese and Spanish) identified
from existing relevant guidelines. International and national infection control guidelines and infection
control textbooks were also consulted. The document has undergone internal and external peer
reviews. The Guideline Steering Group1
evaluated the comments suggested by the reviewers
providing guidance when opinions differed, and oversaw the incorporation of amendments and
finalization of the document.
Pilot tests of the guidelines will be conducted in 2007 and 2008 in each of the six WHO Regions to
help provide local data on clarity of the document and generate information on resources required to
carry out the recommendations, feasibility, and validity of the interventions concerned. The pilot tests
may also help provide information for implementation and dissemination strategies. The guidelines
will be reviewed and updated after the conclusion of the pilot tests.
As in many other areas, the knowledge on modes of transmission of respiratory diseases is evolving
rapidly. In addition, case surveillance and case and contact investigation are critical in defining and
identifying changes in the epidemiology of human infections and will continue to inform infection
control recommendations. Modifications to these guidelines will be made, as necessary, as additional
information becomes available.
