The recommendations in these guidelines promote the use of simple, non-invasive diagnostic tests to assess the stage of liver disease and eligibility for treatment; prioritize treatment for those with most advanced liver disease and at greatest risk of mortality; and recommend the preferred use of n...ucleos(t)ide analogues with a high barrier to drug resistance (tenofovir and entecavir, and entecavir in children aged 2–11 years) for first- and second-line treatment. Recommendations for the treatment of HBV/HIV-coinfected persons are based on the WHO 2013 Consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection, which will be updated in 2015.

WHO recommends replacing western blotting and line immunoassays with simpler tests in HIV testing services. These simpler tests include rapid diagnostic tests (RDTs) that can be used at the point-of-care, and enzyme immunoassays (EIAs).
These tests get results to the client faster, produce accura...te results more often, cost less, can be performed by various cadres of health providers, and can thus facilitate greater access and uptake of HIV testing services among those who need it most.

6 July 2021. Three new nucleic acid amplification test (NAAT) classes are endorsed by WHO and included.
The latest operational handbook includes the new classes recommended by WHO. It aims at facilitating the implementation of the WHO recommendations by the Member States, technical partners, and ot...hers involved in managing patients with TB and DR-TB. The operational handbook provides practical information on existing and new tests recommended by WHO, step-by-step advice on implementing and scale-up testing to achieve local and national impact and lastly, model diagnostic algorithms, which are updated to incorporate the latest recommendations. An overview of budgetary considerations and information sheets on each of the newly recommended tests is provided.

Sequencing enabled the world to rapidly identify SARS-CoV-2 and develop diagnostic tests and other tools for outbreak management. Continued genome sequencing supports the monitoring of the disease’s spread and evolution of the virus. Accelerated integration of genome sequencing int...o the practices of the global health community is required if we want to be better prepared for the future threats. This document provides guidance for laboratories on maximizing the impact of SARS-CoV-2 sequencing now and other emerging pathogens in the future.

Recommendations for national testing strategies for SARS-CoV-2 and diagnostic capabilities
The Updated guidelines on Management of tuberculosis in children and adolescents include new recommendations that cover diagnostic approaches for TB, shorter treatment for children with non-severe drug-susceptible TB, a new option for the treatment of TB meningitis, the use of bedaquiline and delama...nid in young children with multidrug- and rifampicin-resistant TB and decentralized and family-centred, integrated models of care for TB case detection and prevention in children and adolescents.

In 2009, WHO’s Second International Conference on Buruli Ulcer Control and Research resolved to strengthen the capacity of national laboratories to confirm cases of the disease, but advised that “efforts are still needed to develop simple diagnostic tools usable in the field as well as disabilit...y prevention methods”.
In 2013, WHO and the Foundation for Innovative New Diagnostics convened a meeting of Buruli ulcer experts in Geneva, Switzerland (9) at which two priority unmet needs in diagnosis were identified:
a diagnostic test for early detection of Buruli ulcer in symptomatic patients with sufficient positive predictive value to put patients on appropriate treatment; and
a screening test at the primary health care or community level for symptomatic patients with ulcer

Childhood cancer is curable for the vast majority of children when essential diagnostic, therapeutic and supportive care services are accessible. However, profound inequalities in outcomes exist within and between countries with as few as 20% or 30% of children living in low- and middle-income count...ries surviving.
The Global Initiative for Childhood Cancer Overview document presents the CureAll approach to support governments, partners and communities achieve the best possible cancer care for all children. This approach, summarized as four pillars of action supported by three enablers, will improve the care for children with cancer around the world.

The guidance notes describe key actions that policy-makers at national and subnational levels can take in relation to: diagnostic testing for COVID-19, clinical management of COVID-19, meeting targets for vaccination against COVID-19, maintaining infection control measures for COVID-19 in health-car...e settings, building confidence through risk communication and community involvement, and ensuring that all health-care workers are aware of the risks of COVID-19.
This guidance note focuses on the following areas: COVID-19 diagnostic testing, clinical management of COVID-19, achieving COVID-19 vaccination targets, maintaining COVID-19 infection control measures in health-care settings, building confidence through risk communication and community engagement, and managing COVID-19 infodemia. This guidance note focuses on risk communication and community engagement in the context of COVID-19.

For the molecular diagnosis of Chagas disease by real-time PCR (polymerase chain reaction), optimization of diagnostic accuracy is desirable. The detection limit of real-time PCR assays for the diagnosis of Trypanosoma cruzi in human serum is affected by various influences including the choice of th...e nucleic acid extraction assay. In this study, three nucleic acid extraction assays were compared regarding their influence on the sensitivity of a T. cruzi-specific real-time PCR with 62 reference sera containing T. cruzi target DNA (deoxyribonucleotide acid). More than 95% of the positive sera were correctly identified after all three nucleic acid extraction strategies with a detection rate ranging from 96.8% (60/62) for the worst assay to 100% (62/62) for the best one. A matched pairs analysis for the comparison of the cycle threshold (Ct) values obtained with the 59 reference samples with positive real-time PCR results after all three nucleic acid extraction schemes indicated differences in a range of about 3 Ct steps. Summarized, all three compared nucleic acid extraction schemes were basically suitable for T. cruzi-specific PCR from serum with some minor differences. However, in the case of low quantities of circulating parasite DNA in the serum of a patient with Chagas disease, even minor effects can make a difference in the individual diagnosis.

The development of this target product profile (TPP) was led by the WHO Department of Control of Ne-
glected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to
identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG)
was... formed, and different subgroups were created to advise on specific NTDs, including a subgroup
working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of in-
dependent experts included leading scientists, public health officials and endemic-country end-user rep-
resentatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of
the available products and of the development pipeline was conducted, and the salient areas with unmet
needs were identified

One of the main limitations to accessing hearing aids is the lack of diagnostic and rehabilitative services, especially at primary and secondary levels of care. This is due to the small number of specialists in ear and hearing care, and to their poor territorial distribution which is more evident in... low- and middle-income countries
