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.

Le présent guide de formation sur la prise en charge globale des personnes vivant avec le VIH est désormais à la disposition des personnels paramédicaux, des écoles et structures de formation de ces personnels dans la région africaine francophone. Il a été conçu par des experts africains et... français rompus à la formation et engagés depuis de nombreuses années dans la lutte contre le VIH. Il a été testé, amendé et corrigé par un collège de paramédicaux. Il allie clarté, simplicité et intègre l’ensemble des standards internationaux en matière de prise en charge globale, tout en restant proche des réalités concrètes de l’exercice professionnel sur le terrain africain. Il constitue, j’en suis convaincu, un outil de grande qualité au service des professionnels de santé paramédicaux et devrait s’imposer rapidement comme un référentiel francophone incontournable pour la prise en charge globale des personnes vivant avec le VIH.

Soil-transmitted helminths (STH) affect 1.45 billion people worldwide, and high intensity infections are associated with anemia, undernutrition and impaired cognition, particularly among children. Mathematical models suggest it may be possible to interrupt the transmission of STH in a community by e...xpanding mass drug administration (MDA) from targeted high-risk groups (primarily school-aged children and women of child-bearing age) to all community members with high coverage. The DeWorm3 Project will test the feasibility of this approach to interrupting the transmission of STH using a series of cluster randomized trials in Benin, India and Malawi. Each study area (population 80,000) will be divided into 40 clusters and randomized to community-wide or standard-of-care targeted MDA for three years. Two years following the final round of MDA, prevalence of STH will be compared between arms and transmission interruption assessed in each cluster. The DeWorm3 trials will provide stakeholders with information regarding the potential to switch from STH control to a more ambitious and sustainable strategy.

Yaws is targeted for eradication by 2030, using a strategy based on mass drug administration (MDA) with azithromycin. New diagnostics are needed to aid eradication. Serology is currently the mainstay for yaws diagnosis; however, inaccuracies associated with current serological tests makes it difficu...lt to fully assess the need for and impact of eradication campaigns using these tools. Under the recommendation of the WHO Diagnostic Technical Advisory Group (DTAG) for Neglected Tropical Diseases(NTDs), a working group was assembled and tasked with agreeing on priority use cases for developing target product profiles (TPPs) for new diagnostics tools.

1st edition.
Unitaid’s report describes a slate of new devices that can more efficiently identify dangerously ill children so that they can be treated immediately. These tools make it easier to recognize danger signs, and support integrated approaches to reducing childhood deaths from the three ...greatest childhood killers: malaria, pneumonia and diarrhoea.
The report also highlights tests that can determine whether or not a child has an illness that can be treated with antibiotics. Viral infections are a common cause of childhood fevers, but cannot be cured with antibiotics. Although many children seeking care at clinics have fever, three-quarters by some estimates, only a small fraction of those have an illness that can be treated with an antimalarial or antibiotic drug

Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after exposure to a probable or confirmed case of SARS-CoV-2 i...nfection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

Policy considerations
for the WHO European Region
This document provides key considerations for Member States to help them to decide on the modulation
of large-scale restrictive public health measures
(i.e. movement restrictions and large-scale physical distancing), while at the... same time strengthening core public health service capacities (to identify, isolate,
test and treat every patient and quarantine contacts) together with personal protective measures (hand hygiene and respiratory etiquette) and individual physical distancing (>1 metre distance). The transition should be informed by national, subnational or even community-level risk assessments as the transmission of COVID-19 is typically not homogeneous within a country.

About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance.

Overwhelming evidence shows that a range of health concerns—mental illness, substance dependence, HIV/AIDS, and noncommunicable diseases—affect prisoners disproportionately. But, while incarceration poses risks to health—including inadequate nutrition and exposure to violence—prisons also pr...esent important opportunities to promote health and risk reduction that need to be tapped.
Some recommended remedies:
Health ministries, not ministries of justice, should manage health care responsibilities
Ensure that testing is available, but not mandatory, for infectious diseases
Make prison health part of the broader public health agenda

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

Vaccines are powerful weapons in the fight against pandemic viruses as shown by responses to both the 2009 H1N1 influenza and the COVID-19 pandemics. However, planning for accessing, allocating and deploying vaccines in a pandemic situation is a complex endeavour, beset with multiple challenges at a...ll levels – local, regional and global. The World Health Organization (WHO) and its partners have prepared this revised guidance document to assist countries update their national deployment and vaccination plans (NDVPs) by leveraging global learnings from past pandemic responses, including the recent COVID-19 vaccination effort. The development and testing of a NDVP would not only advance pandemic preparedness efforts but would also have benefits in terms of increasing national capabilities to manage other health emergencies which require emergency vaccination campaigns.

All young people, including those with special needs and from the most vulnerable groups, have the right to quality health care services. Unfortunately, this right is not a reality, particularly in the case of sexual and reproductive health services. Many youth in need of sexual and reproductive hea...lth care may either decline or be denied access to health services for a variety of reasons: Providers are often biased and do not feel comfortable serving youth who are sexually active; youth do not feel comfortable accessing existing services because they are not "youth-friendly" and may not meet their needs; and, often, community members do not feel that youth should have access to sexual and reproductive health services.
To address provider and site bias toward serving youth, EngenderHealth created a training curriculum intended to sensitize all staff at a health care facility on the provision of youth-friendly services. The curriculum was created as a result of the participatory work that we have been doing with youth in Nepal to address the needs of all levels of providers at different service-delivery settings. The curriculum has been field-tested and used in Nepal, Russia, Mongolia, and the United States.
Youth-Friendly Services allows staff to reflect upon and assess their own beliefs about adolescent sexuality while ensuring that those values and attitudes do not compromise the basic sexual and reproductive health rights to which youth are entitled. The curriculum also helps providers understand cross-cultural principles of adolescent development and health needs specific to youth. Once participant knowledge, attitudes, and skills are improved, sites conduct a self-assessment on the youth-friendliness of their services and create an action plan for specific improvements.

2nd edition. Children with TB comprise about 10-12% of the total TB cases diagnosed in the country. This burden is likely to be higher given the challenges in diagnosing TB in children. The symptoms of TB in children mimic those of other childhood diseases. Children do not readily expectorate and th...ey have pauci-bacillary TB hence some will be missed using bacteriological tests. The government has however introduced GeneXpert molecular testing that is more sensitive than microscopy in detecting TB. Health care workers therefore need a reference guide to obtaining sputum from children for testing. Treatment of TB in children has been reviewed and now includes Ethambutol. There are now improved paediatric friendly TB medicines for treatment of TB in children and health care workers need a reference guide to enable them accurately dispense the TB medicine to children. Malnutrition is a common predisposing factor for TB in children. On the other hand, TB predisposes children to malnutrition or worsens an existing state of malnutrition. Nutrition care and support forms an integral part of treatment for a child with TB disease.
