9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

Tuberculosis (TB) is an infectious disease that usually affects the lungs, though it can affect any organ in the body. It can develop when bacteria spread through droplets in the air. TB can be fatal, but in many cases, TB is preventable and treatable. This report examines the human rights impact of... the prevalence of Tuberculosis (TB) and Multi-drug-resistant tuberculosis (MDR-TB) among the Indigenous San peoples of Namibia. Combining political economy and root-cause methodology, the report explores the socioeconomic factors that make the San vulnerable to TB and limit their access to adequate health services.

Systematic screening for TB disease is the systematic identification of people at risk for TB disease, in a predetermined target group, by assessing symptoms and using tests, examinations or other procedures that can be applied rapidly.
Systematic screening can benefit people who are at risk of get...ting TB, as early detection and start of treatment can improve their outcomes and reduce their costs. It can also benefit entire communities at higher risk for TB, by reducing the prevalence of TB disease and preventing future cases.

To assess the impact of the COVID-19 pandemic on health and HIV expenditure, UNAIDS carried out a modelling study on fiscal space for health and HIV. From a sample of 28 countries, three countries—the Democratic Republic of the Congo, Jamaica, and Lesotho—were selected to capture health and HIV ...expenditure impacts across countries with especially marked differences in burdens of disease (including HIV prevalence), HIV donor dependency, level of economic development, and geographic location. While the three-country sample is too small to permit findings to be generalized to other countries, these analyses are useful for informing UNAIDS’ work to identify some policy positions to minimize the COVID-19 pandemic’s impact on the HIV response.

The number of confirmed COVID-19 cases detected and reported in each country is influenced by
many factors including limited access and/or utilization of healthcare and COVID-19 testing, limited
surveillance, lack of knowledge amongst the population about when to seek testing, an asymptomatic pres...entation, and other unknown issues. This is true in all countries of the world, and not Africa specific, however there are factors unique to Africa which may also affect the way the virus behaves there. COVID-19 prevalence data are critical for planning effective mitigation strategies and understandingthe true impact of the disease and relevant intervention measures in Africa, which might be quite different from regions with a different population age distribution or risk factor profile.

High levels of storage iron may increase malaria susceptibility. This risk has not been investigated in semi-immune adolescents. We investigated whether baseline iron status of nonpregnant adolescent girls living in a high malaria transmission area in Burkina Faso affected malaria risk during the fo...llowing rainy season. For this prospective study, we analysed data from an interim safety survey, conducted six months into a randomised iron supplementation trial. We used logistic regression to model the risk of P. falciparum infection prevalence by microscopy, the pre-specified interim safety outcome, in relation to iron status, nutritional indicators and menarche assessed at recruitment.

Le Gouvernement du Burkina Faso a pris en compte au niveau du deuxième axe stratégique du Plan National de Développement Economique et Social (PNDES) 2016 – 2020 la nécessité de développer des actions allant dans le sens de la mitigation de l’impact du VIH sur les... populations. Deux CSLS successifs couvrant les périodes 2001-2005 et 2006 – 2010 ont été mis en œuvre contribuant de manière significative à baisser et à stabiliser la progression de la pandémie, en ramenant le taux de séroprévalence de 7,17% en 1997 à 0.90% en fin 2014 selon les estimations de l’ONUSIDA. Malgré cette évolution positive, le Burkina Faso demeure en situation d’épidémie généralisée. Ce même rapport mentionne que le nombre de PVVIH est estimé à 110.000, dont 57.000 femmes. 75.000 enfants sont estimés orphelins du fait du Sida. L’EDS IV réalisée en 2010 note que la prévalence en population générale présente des disparités selon le sexe. En effet, les femmes ont une prévalence de 1.2% contre 0.8% chez les hommes d’où un ratio H/F de 1.5 confirmant ainsi la théorie de la féminisation de l’infection pour des raisons à la fois socio-économiques et biologiques. Une étude récente conduite par le SP/CNLS ciblant les travailleuses du sexe (TS) a montré une prévalence au VIH de 16,19%, c’est à dire plus de 16 fois celle en population générale.

Las infecciones de transmisión sexual (ITS) constituyen un importante problema de salud pública en todo el mundo, que afecta a la calidad de vida y se acompaña de importantes niveles de morbilidad y mortalidad. Estas infecciones influyen directamente en la salud infantil y reproductiva porque tra...en consigo infertilidad, cánceres y complicaciones del embarazo. También tienen una influencia indirecta porque facilitan la transmisión por vía sexual del virus de la inmunodeficiencia humana (VIH), pesando así igualmente en la economía de los países y las personas. Cada día, más de un millón de personas contraen una infección de transmisión sexual. Se calcula que en 2012 hubo en el mundo 357 millones de nuevos casos de ITS curables (blenorragia, clamidiasis, sífilis o tricomoniasis) que afectaron a adultos de entre 15 y 49 años de edad, entre ellos 5,6 millones de casos de sífilis. El número de casos prevalentes de sífilis asciende, según las estimaciones, a unos 18 millones.

Fetal alcohol spectrum disorders (FASD) represent a range of physical, mental, and behavioral disabilities caused by alcohol use during pregnancy, or prenatal alcohol exposure (PAE). FASDs are considered to be one of the leading preventable causes of developmental disability. Despite its high preval...ence, FASD is often misdiagnosed or underdiagnosed, making interventions more challenging or delayed.
his publication was initially developed for use in Spanish-speaking countries of the Americas and is intended to serve as a training workbook for providers of various disciplines to learn about the fundamentals of diagnosing FASD and to apply them to several case scenarios. It also discusses ethical implications of diagnosing FASD to the mother and child. Target audiences include physicians, psychologists, allied health professionals, social workers, and other providers that may encounter individuals affected by FASD. It is ideally used as a supplement for in-person training by experts in the fields of dysmorphology, epidemiology, and neuropsychology.

Viral hepatitis is defined as inflammation of the liver cells due to viral infection. The burden of liver disease in South Africa is mostly underestimated as viral hepatitis, in particular chronic infection, is a silent and neglected cause of morbidity and mortality. However, the burden of disease i...s likely substantial given the prevalence of chronic viral hepatitis. This burden is further compounded by the lack of screening and access to care and treatment as well as inadequate disease surveillance, human and financial resources.
The National Guidelines for the Management of Viral Hepatitis were developed, with the purpose to:
inform healthcare workers in the public and private sectors about the disease, its epidemiology in South Africa and current methods of diagnosis and therapy
strengthen the healthcare response to viral hepatitis
empower communicable diseases workers and stakeholders to make informed decisions regarding appropriate and cost effective interventions

Policy brief. HIV testing services (HTS) and anti-retroviral therapy (ART) have been scaled up substantially. It is estimated that, globally, nearly 80% of people with HIV now know their status. With the offer of immediate ART initiation and improved treatment options, access to and uptake of treatm...ent have increased, too. Now, most people with HIV who know their status are obtaining treatment and care.
In response to these changes in the global HIV epidemic, WHO is encouraging countries to use three consecutive reactive tests for an HIV-positive diagnosis as their treatment-adjusted prevalence and national HTS positivity fall below 5% .

Objetivos.
Estimar la carga de tuberculosis (TB) en menores de 15 años y describir las características clínico, epidemiológicas y los resultados del tratamiento antituberculoso en Ecuador.
Métodos.
Se realizó un estudio retrospectivo utilizando los datos del programa nacional de TB de los... años 2015 y 2016. Se estimaron la tasa y el porcentaje de casos de TB infantil y se describieron las características de la enfermedad y el resultado del tratamiento según las categorías de edad: 0-4, 5-9 y 10-14 años.
Resultados.
De los 10 991 casos de TB diagnosticados, 223 (2,03%) fueron menores de 15 años; según la región del país esta carga varió entre 0 y 5,5%. De los 223 casos, en 213 se había registrado el resultado del tratamiento y fueron incluidos en el estudio; 78 (37%) eran menores de 5 años y en 147 (69%) no hubo registro de la investigación de contactos. Sesenta y cinco (68%) de los adolescentes y 40 (51%) de los menores de 5 años tenían diagnóstico de TB pulmonar. La prevalencia de VIH fue 11,5% en los menores 5 años y 6,3% en el grupo de 10-14 años. El tratamiento fue satisfactorio en el 93% de los casos, (curación, 36,6%, tratamiento terminado, 56,8%).
Conclusiones:
Ecuador presenta un alto porcentaje de subdiagnóstico de TB infantil y una carga menor a la esperada, principalmente en menores de 5 años. La alta prevalencia de VIH y la falta de sistematización adecuada de la investigación de contactos en los adolescentes revelan la necesidad de considerar estrategias centradas en la familia y que involucren la capacitación del personal de salud en el manejo del paciente pediátrico centrándose en las necesidades específicas de cada población.
