Geneva, Switzerland, WHO, 2013.  p. (WHO/HTM/NTD/WHOPES/2013.3)Guidelines for testing long-lasting insecticidal nets (LNs) were first published by WHO in 2005. The revised guidelines were reviewed by a WHOPES informal consultation on innovative public health pesticide products, held at WHO headquarters on 22-26 October 2012. Industry was invited to attend the first 2 days of the meeting to exchange information and provide their views, after which their comments were further reviewed by a group of WHO-appointed experts, who finalized the guidelines by consensus. The purpose of this document is to provide specific, standardized procedures and guidelines for testing LNs for personal protection and malaria vector control. It is intended to harmonize testing procedures in order to generate data for registration and labelling of such products by national authorities and provide a framework for industry in developing novel LN products. This document replaces the previous guidelines, published by WHOPES in 2005. (Excerpts)
Geneva, Switzerland, WHO, 2010.  p.The World Health Organization Guidelines for the treatment of malaria provides evidence-based and up-to-date recommendations for countries on malaria diagnosis and treatment which help countries formulate their policies and strategies. In scope, the Guidelines cover the diagnosis and treatment of uncomplicated and severe malaria caused by all types of malaria, including in special groups (young children, pregnant women, HIV / AIDS), in travellers (from non-malaria endemic regions) and in epidemics and complex emergency situations. The first edition of the Guidelines for the treatment of malaria were published in 2006. The second edition introduces a new 5th ACT to the four already recommended for the treatment of uncomplicated malaria. Furthermore, the Guidelines recommend a parasitological confirmation of diagnosis in all patients suspected of having malaria before treating. The move towards universal diagnostic testing of malaria is a critical step forward in the fight against malaria as it will allow for the targeted use of ACTs for those who actually have malaria. This will help to reduce the emergence and spread of drug resistance. It will also help identify patients who do not have malaria, so that alternative diagnoses can be made and appropriate treatment provided. The new Guidelines will therefore help improve the management of not only malaria, but other childhood febrile illnesses.
Antiretroviral resistance patterns and HIV-1 subtype in mother-infant pairs after the administration of combination short-course zidovudine plus single-dose nevirapine for the prevention of mother-to-child transmission of HIV.
Clinical Infectious Diseases. 2009 Jul 15; 49(2):299-305.BACKGROUND: World Health Organization guidelines for prevention of mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) recommend administration of zidovudine and single-dose nevirapine (NVP) for HIV-1-infected women who are not receiving treatment for their own health or if complex regimens are not available. This study assessed antiretroviral resistance patterns among HIV-infected women and infants receiving single-dose NVP in Thailand, where the predominant circulating HIV-1 strains are CRF01_AE recombinants and where the minority are subtype B. METHODS: Venous blood samples were obtained from (1) HIV-infected women who received zidovudine from 34 weeks' gestation and single-dose NVP plus oral zidovudine during labor and (2) HIV-infected infants who received single-dose NVP after birth plus zidovudine for 4 weeks after delivery. HIV-1 drug resistance testing was performed using the TruGene assay (Bayer HealthCare). RESULTS: Most mothers and infants were infected with CRF01_AE. NVP resistance was detected in 34 (18%) of 190 women and 2 (20%) of 10 infants. There was a significantly higher proportion of NVP mutations in women with delivery viral loads of >50,000 copies/mL (adjusted odds ratio, 8.5; 95% confidence interval, 2.2-32.8, [Formula: see text] for linear trend) and in those with subtype B rather than CRF01_AE infections (38% vs. 16%; adjusted odds ratio, 3.6; 95% confidence interval, 1.1-11.8; P = .038). CONCLUSIONS: The lower frequency of NVP mutations among mothers infected with subtype CRF01_AE, compared with mothers infected with subtype B, suggests that individuals infected with subtype CRF01_AE may be less susceptible to the induction of NVP resistance than are individuals infected with subtype B.
Geneva, Switzerland, World Health Organization [WHO], Stop TB Department, 2006.  p. (WHO/HTM/TB/2006.361)The emergence of resistance to drugs used to treat tuberculosis (TB), and particularly multidrug-resistant TB (MDR-TB), has become a significant public health problem in a number of countries and an obstacle to effective global TB control. In many other countries, the extent of drug resistance is unknown and the management of patients with MDR-TB is inadequate. In countries where drug resistance has been identified, specific measures need to be taken within TB control programmes to address the problem through appropriate management of patients and adoption of strategies to prevent the propagation and dissemination of drug-resistant TB, including MDR-TB. These guidelines offer updated recommendations for TB control programmes and medical workers in middle- and low-income countries faced with drug-resistant forms of TB, especially MDR-TB. They replace two previous publications by the World Health Organization (WHO) on drug-resistant TB. Taking account of important developments in recent years, the new guidelines aim to disseminate consistent, up-to-date recommendations for national TB control programmes and medical practitioners on the diagnosis and management of drug-resistant TB in a variety of geographical, political, economic and social settings. The guidelines can be adapted to suit diverse local circumstances because they are structured around a flexible framework approach, combining a consistent core of principles and requirements with various alternatives that can be tailored to the specific local situation.

Instructions for applying to the Green Light Committee for access to second-line anti-tuberculosis drugs.
[Geneva, Switzerland], World Health Organization [WHO], 2006. 15 p. (WHO/HTM/TB/2006.369)Controlling multi-drug resistant tuberculosis (MDR-TB) is one of the six components of the WHO Stop TB strategy. Although prevention must be the highest priority for TB control programmes, many countries have patients with drug-resistant TB who must be treated too. Such countries should take specific measures to gradually incorporate appropriate strategies for treatment of this form of tuberculosis into their programmes and prevent propagation of drug-resistant TB. Misuse of second-line anti-TB drugs results in further resistance to these same second-line drugs, creating incurable forms of tuberculosis. It is imperative that second-line anti-TB drugs are used wisely. The WHO Guidelines For The Programmatic Management of Drug Resistant Tuberculosis (herein after referred to as the Guidelines) provide recommendations for appropriate management of drug-resistant TB so as not to generate further drug resistance. To help programmes develop and implement develop and implement strategies for the management of drug resistant TB, the Green Light Committee for Access to Second-line Anti-tuberculosis Drugs (GLC) was created by WHO and its partners in January 2000.

Scaling up antiretroviral therapy in resource-limited settings. Guidelines for a public health approach. Executive summary.
Geneva, Switzerland, WHO, Department of HIV / AIDS, 2002 Apr. 31 p.Currently, fewer than five per cent of those who require ARV treatment can access these medicines in resource limited settings. WHO believes that at least three million people needing care should be able to get medicines by 2005—a more than ten-fold increase. These guidelines are intended to support and facilitate the proper management and scale-up of ART in the years to come by proposing a public health approach to achieve these goals. The key tenets of this approach are: 1) Scaling up of antiretroviral treatment programmes to meet the needs of people living with HIV/AIDS in resource-limited settings; 2) Standardization and simplification of ARV regimens to support the efficient implementation of treatment programmes; 3) Ensuring that ARV treatment programmes are based on the best scientific evidence, in order to avoid the use of substandard treatment protocols which compromise the treatment outcome of individual clients and create the potential for emergence of drug resistant virus.

Scaling up antiretroviral therapy in resource-limited settings. Guidelines for a public health approach.
Geneva, Switzerland, WHO, Department of HIV / AIDS, 2002. 163 p.These guidelines are part of the World Health Organization’s commitment to the global scale-up of antiretroviral therapy. Their development involved international consultative meetings throughout 2001, in which more than 200 clinicians, scientists, government representatives, representatives of civil society and people living with HIV/AIDS from more than 60 countries participated. The recommendations included in this document are largely based on a review of evidence and reflect the best current practices. Where the body of evidence was not conclusive, expert consensus was used as a basis for recommendations. We hope that this guidance will help Member countries as they work towards meeting the global target of having three million people on antiretroviral therapy by 2005. (excerpt)
Geneva, Switzerland, WHO, 2003. 79 p.The purposes of the HDRST include: 1) to work with the National AIDS Committee to consider the specific public health uses of HIV drug resistance surveillance in the country, and to assess feasibility of surveillance; 2) to develop an appropriate time line for resistance surveillance activities, in coordination with other important implementation plans such as expanding HIV treatment; 3) to assess the country's capacity for HIV drug resistance surveillance, to decide on the populations and groups to be targeted, and to identify additional resources and activities needed; 4) to perform HIV drug resistance threshold surveys to assess when the frequency of resistance in persons newly diagnosed with HIV has reached the 5% threshold indicating a need for resistance surveillance; 5) to implement, when appropriate, HIV drug resistance surveillance; 6) to collaborate with the National AIDS Committee and the national treatment programme; to explore the feasibility of treatment programme monitoring by adding a resistance monitoring component to other year-end programme monitoring activities; 7) after routine surveillance is established, to consider implementing other special studies for in-depth evaluation of certain aspects of drug resistance within the country; 8) to insure implementation of all activities in accordance with international ethical standards designed to promote the well- being and health of individuals and communities; 9) to insure the dissemination of results in order to promote and support the public health of the country.

Geneva, Switzerland, WHO, 2003. vii, 91 p.Sexually transmitted infections (STIs) are among the most common causes of illness in the world and have far-reaching health, social and economic consequences for many countries. The emergence and spread of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) have had a major impact on the management and control of STIs. At the same time, resistance of several sexually transmitted pathogens to antimicrobial agents has increased, adding to therapeutic problems. In 1991, WHO published recommendations for the comprehensive management of patients with STIs within the broader context of control, prevention and care programmes for STI and HIV infection. WHO convened an Advisory Group Meeting on Sexually Transmitted Diseases Treatment in May 1999 to review and update treatment recommendations in the light of recent developments. In November 2001, an expert consultation on improving the management of STIs was convened by WHO in Geneva. The consultation focused on the syndromes of genital ulcers and vaginal discharge. The former because of the observed increase of herpes simplex virus type 2 (HSV2) as the main cause of genital ulcers in developing countries, and the latter for its continued complexity and controversy as an entry point for managing cervical gonococcal and chlamydial infections. Recommendations from the consultation have led to the revisions included in this publication, covering the two areas of syndromic management of genital ulcer disease and vaginal discharge. (excerpt)
Scaling up antiretroviral therapy in resource-limited settings: treatment guidelines for a public health approach. Rev. ed.
Geneva, Switzerland, WHO, 2003. 67 p.Currently, fewer than 5% of people in developing countries who need ART can access the medicines in question. WHO believes that at least 3 million people needing care should be able to get the medicines by 2005. This represents almost a tenfold increase. These treatment guidelines are intended to support and facilitate the proper management and scale-up of ART in the years to come by proposing a public health approach to achieve the goals. The key tenets of this approach are as follows. 1) Scaling-up of antiretroviral treatment programmes with a view to universal access, i.e. all persons requiring treatment as indicated by medical criteria should have access to it. 2) Standardization and simplification of ARV regimens so as to support the efficient implementation of treatment programmes in resource-limited settings. 3) Ensuring that ARV treatment programmes are based on scientific evidence in order to avoid the use of substandard protocols that compromise the outcomes of individual patients and create a potential for the emergence of drug-resistant virus. However, it is also important to consider the realities with respect to the availability of human resources, health system infrastructures and socioeconomic contexts so that clear and realistic recommendations can be made.
