This document provides detailed guidance on laboratory testing for suspected diphtheria cases during significant outbreaks or in low-resource settings. It aims to supplement and build on other existing WHO guidance documents on surveillance standards, diagnostics and research on Corynebacterium by p...roviding key considerations for laboratories that allow the rationalization and optimization of testing during outbreaks. The recommendations given here have been prepared by WHO in consultation with, and reviewed by, global experts with experience in laboratory analysis of Corynebacterium species and in outbreak settings, or with expertise in developing new technologies for diphtheria research and diagnosis. Unless otherwise stated, the considerations provided apply to diphtheria outbreaks caused by toxin-producing C. diphtheriae with a classical respiratory diphtheria presentation.

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

Despite progress in improving antiretroviral therapy (ART) for people with HIV in Malawi, the burden of HIV infections and HIV treatment outcomes among key populations is suboptimal. Client-centered differentiated service delivery approaches may facilitate addressing HIV prevention and treatment nee...ds of key populations in Malawi.
Methods
De-identified program data routinely collected as part of the LINKAGES project–Malawi were assembled from October 2017 to September 2019. HIV case finding was compared across different testing modalities for each population. Poisson regression was used to estimate the association between testing modalities and ART initiation.
Results
Of the 18 397 people included in analyses, 10 627 (58%) were female sex workers (FSWs), 2219 (12%) were men who have sex with men (MSM), and 4970 (27%) were clients of FSWs. HIV case finding varied by modality and population, with index testing and enhanced peer outreach demonstrating high yield despite reaching relatively few individuals. FSWs who tested positive through risk network referral testing were more likely to initiate ART within 30 days compared with those who tested positive through clinic-based testing (adjusted risk ratio [aRR], 1.50; 95% CI, 1.23–1.82). For MSM, index testing (aRR, 1.45; 95% CI, 1.06–2.00) and testing through a drop-in center (aRR, 1.82; 95% CI, 1.19–2.78) were associated with 30-day ART initiation.
Conclusions
These data suggest that differentiated HIV testing and outreach approaches tailored to the needs of different key populations may facilitate improved ART initiation in Malawi. Achieving 0 new infections by 2030 suggests the need to adapt treatment strategies given individual and structural barriers to treatment for key populations with HIV in high-prevalence settings.

This manual has been designed to be used in conjunction with two earlier WHO publications, "Basic tests for pharmaceutical substances" (1986) and "Basic tests for pharmaceutical dosage forms" (1991). Most of the pharmaceutical substances and dosage forms covered are included in the WHO Model List of... Essential Drugs. The present volume describes procedures for testing a further 23 pharmaceutical substances and 58 pharmaceutical dosage forms and also for testing 4 medicinal plant materials.

Dengue testing guidance according to days of symptom onset.
Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

Multivariable logistic regression models were constructed to estimate the proportion completing same-visit HIV testing, comparing between those with and without TB symptoms.

In Myanmar, men who have sex with men (MSM) experience high risk of HIV infection. However, access to HIV testing and prevention services remains a challenge among this marginalized population. The objective of this study was to est...imate population prevalence and correlates of prior HIV testing among young MSM (YMSM) and informs the development of HIV testing and intervention programmes that respond to the specific needs of this population.
