The aim of this handbook is to provide network members and other laboratories involved in the diagnosis of tuberculosis, with an agreed list of key diagnostic methods and their protocols in various areas of TB diagnosis, ranging from microbiological diagnosis of active TB to the diagnosis of latent ...TB infection. This handbook offers a single source of reference by compiling all methods, with a strong focus on standard (reference) and evidence-based methods. In so doing, it will also contribute to the improvement of disease surveillance data for Europe.

Polymerase Chain Reaction (PCR) has significantly helped in early diagnosis and commencement of specific interventions for diseases control. It also plays a critical role in understanding the disease epidemiology and unraveling the transmission dynamics of the disease. This manual intends to p...rovide primary guidelines to assist health lab personnel in developing countries to establish a PCR diagnostic facility for efficient support to patient care as well as public health actions.

The modules (1-12) are based on materials originally developed by FIND, KNCV and Cepheid, and are in PowerPoint format for country customization. Depending on the audience, modules may be selected and adapted according to need (e.g. basic users, supervisors, clinicians). Topics covered include: Over...view of TB and diagnostics, biosafety, specimen collection, procurement, installation, Xpert MTB/RIF technology, results interpretation, reporting, troubleshooting, maintenance, a clinical guide, and quality assurance.

This document provides countries with recommendations for structuring a public health entomology laboratory network. The document will help countries to identify their areas of need and determine how the entomology network can be strengthened, especially in the context of a decentralized health syst...em. The recommendations also consider the different degrees of development and different entomological research needed to support disease prevention and control activities.

Taeniasis and cysticercosis caused by the parasite T. solium affect vulnerable populations,
mainly in Latin America, sub-Saharan Africa and Asia, where pigs (the intermediate host) roam
free and poor sanitation allows pigs access to human faeces.
This study addresses part of the Terms of Reference for a scoping report ‘An analysis of approaches to laboratory capacity strengthening for drug resistant infections in low and middle income countries’. It has been produced as a separate report because it is also very relevant for a second stud...y ‘Supporting Surveillance Capacity for Antimicrobial Resistance: Regional Networks and Educational Resources’. This study compares antimicrobial surveillance systems in three low and middle income countries in order to describe the components of these systems and to understand which surveillance models are best suited to particular contexts. Ghana, Nigeria and Nepal were selected as study countries because they cover different continents and include one ‘fragile’ context (Nigeria). Brief information from Malawi is also included.

Schistosoma haematobium is a parasitic digenetic trematode responsible for schistosomiasis (also known as bilharzia). The disease is caused by penetration of the skin by the parasite, spread by intermediate host molluscs in stagnant waters, and can be treated by administration of praziquantel. Schis...tosomiasis is considered to be an important but neglected tropical disease.

This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

This is the ninth paper in our series, “Community Health Workers at the Dawn of a New Era”. Community health workers (CHWs) are in an intermediary position between the health system and the community. While this position provides CHWs with a good platform to improve community health, a major cha...llenge in large-scale CHW programmes is the need for CHWs to establish and maintain benefcial relationships with both sets of actors, who may have diferent expectations and needs. This paper focuses on the quality of CHW relationships with actors at the local level of the national health system and with communities.
