This document highlights 10 well established Risk Communication and Community Engagement (RCCE) principles that have proven their power. Together they put communities at the heart of the roll out of new vaccines, treatments and tests and promote trust, the critical ingredient for al...l community action. Informed, engaged and empowered communities are the bedrock for the arrival of new vaccines, treatments and tests that will be introduced to reduce the spread of COVID-19 and save lives. With communities fully engaged and actively participating through the full cycle of planning, delivery and assessment for biomedical tools, demand for these tools can be increased, leading to widespread and effective uptake and use

Neglected tropical diseases tend to cluster in the same poor populations, and to make progress with their control, they will have to be dealt with in an integrated manner. Peptide microarrays may be a solution to tese problems, where diagnosis for co-infection can be detected simultaneously using th...e one tool.

To test for ethnic discrimination in access to outpatient health care services, we carry out
an email-correspondence study in Germany. We approach 3,224 physician offices in the 79
largest cities in Germany with fictitious appointment requests and randomized patients’
characteristics. We find t...hat patients’ ethnicity, as signaled by distinct Turkish versus Ger-
man names, does not affect whether they receive an appointment or wait time. In contrast,
patients with private insurance are 31 percent more likely to receive an appointment. Hold-
ing a private insurance also increases the likelihood of receiving a response and reduces the
wait time. This suggests that physicians use leeway to prioritize privately insured patients
to enhance their earnings, but they do not discriminate persons of Turkish origin based
on taste. Still, their behavior creates means-based barriers for economically disadvantaged
groups.

This guidance addresses rationale, risk-based scenarios, practical considerations prior to adoption of the self-testing products, quality assurance, safety and ethical considerations, and data management considerations for COVID-19 self-testing. The Africa CDC recommends the use of rapid antigen sel...f-testing within two key scenarios. The first includes testing for case identification within scenarios with a high risk of infection, including symptomatic cases and contacts of a confirmed case. The second scenario involves general screening within scenarios of low or unknown risk exposure allowing for self-care such as before gatherings with at-risk individuals and prior to participation in events involving members of different households. Within these scenarios, a positive test result indicates likelihood of current infection, while a negative test result indicates a lower risk of active infection, though it does not rule out infection altogether. All positive cases should be managed following the national COVID-19 management protocol of Member States.ssur

This document updates recommendations for HIV testing by laboratories in the United States and offers approaches for reporting test results to persons ordering HIV tests and to public health authorities. The recommended algorithm is a sequence of tests used in combination to improve the accuracy of ...the laboratory diagnosis of HIV based on testing of serum or plasma specimens. The updated recommendations also include tests for HIV antigens and HIV nucleic acid because studies from populations at high risk for HIV demonstrate that antibody testing alone might miss a considerable percentage of HIV infections detectable by virologic tests

FIND and Standard Diagnostics (SD) have developed a lateral flow rapid diagnostic test (RDT) to screen for
T.b. gambiense HAT that is cheap and easy to use. The tests are packed individually and are stable at 40°C for
up to 25 months; they are performed on fresh blood obtained from a finger prick..., and no instrument or electricity is required. The RDT detects host antibodies to infection in populations that are at risk, or in suspect individuals. Positive cases are subjected to further confirmatory methods to identify HAT patients.

Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Policy brief.
HIV self-testing (HIVST) is a convenient and confidential option for HIV testing. In 2016 WHO recommended HIVST as a safe, accurate and effective way to reach people who may not test otherwise, including people from key populations, men and young people. Lay users can perform HIVST r...eliably and accurately and achieve performance comparable to that of trained health-care workers.
Globally, many countries have developed HIVST policies, and implementation is growing rapidly. This policy brief highlights new guidance to optimize HIVST implementation, including effective service delivery models, linkage to care and support tools.

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.

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.

Interium guidance, 25 June 2021Timely and accurate diagnostic testing is an essential tool in preventing and controlling the spread of COVID-19. This document describes recommendations for national testing strategies and the use of PCR and rapid antigen tests in different transmission scenarios of t...he COVID-19 outbreak, including how testing might be rationalized in low resource settings. All testing should be followed by a strong public health response including isolating those who test positive and providing them care, contact tracing and quarantine of contacts.
