Similar to other parts of the world, the prevalence of type 2 diabetes mellitus (T2DM) in the Asia-Pacific Region has rapidly increased during the last few decades. The purposes of this pilot study were to determine the feasibility and the effects of a capacity building program for Village Health Vo...lunteers (VHVs) to support self-management in a T2DM high risk population from a rural subdistrict in Northeast Thailand. Both quantitative and qualitative data were collected using surveys, focus group discussions, and in-depth interviews. Data were analyzed and used to develop a 12-week capacity building program for VHVs. This program was then implemented on 60 subjects at high risk of T2DM in the selected community. According to the paired t-test and Wilcoxon-signed rank test, VHVs had higher scores on knowledge and self-efficacy of T2DM prevention after a 12 week intervention (p =.03 and p =.02, respectively). Study participants at risk for T2DM also had a significant increase in T2DM knowledge and self-management (p <.001). Implementation of the capacity building program for VHVs in Northeast Thailand was feasible. The key successes were strong community bonding, community empowerment, and support from family and public health nurses. Effects of the program should be examined with those in other Asia-Pacific countries.

This report aims to estimate the economic cost of providing regular access to healthcare for migrants in an irregular situation, compared with the cost of providing treatment in emergency cases only. Two specific medical conditions – hypertension and prenatal care – were selected as examples, an...d their associated costs were calculated using an economic model. This model was then applied to three EU Member States: Germany, Greece and Sweden. The testing suggests that providing access to regular preventive healthcare for migrants in an irregular situation
would be cost-saving for governments.

The COVID-19 pandemic has led to large increases in healthcare waste, straining under resourced healthcare facilities and exacerbating environmental impacts from solid waste. This report quantifies the additional COVID-19 healthcare waste generated, describes current healthcare waste management syst...ems and their deficiencies, and summarizes emerging best practices and solutions to reduce the impact of waste on human and environmental health. The recommendations included in the report build on actions in the WHO manifesto for a healthy recovery from COVID-19: prescriptions and actionables for a healthy and green recovery. They target the global, national and facility levels to promote a “win–win” scenario for COVID-19 PPE use, testing and vaccinations that are safe and support environmental sustainability.

Access to safe blood and blood products is recognized as one of the key requirements for delivery of modern health care in the journey towards health for all. The foundation of safe and sustainable blood supplies depends on the collection of blood from voluntary non-remunerated and low-risk donors. ...Data from the WHO Global Database for Blood Safety (GDBS) brings out several inadequacies related to the supply and safety of blood and blood products. These inadequacies include a number of variations in safe blood practices across the world, including the quantity of blood donated (voluntary and replacement types), quality and adequate testing of the donated blood (immunohaematology [IH] and transfusion-transmitted infections [TTIs]), rational use of blood and blood components such as appropriate patient blood management protocols. These variations are very high in countries of the South-East Asian Region and most of them are either low- or middle-income countries (LMICs).

Little is known about asthma control in the rising number of African children who suffer from this condition. The Achieving Control of Asthma in Children in Africa (ACACIA) study is an observational study collecting evidence about paediatric asthma in urban areas of Ghana, Malawi, Nigeria, South Afr...ica, Uganda and Zimbabwe. The primary objectives are: (1) to identify 3000 children aged between 12 years and 14 years with asthma symptoms; and (2) to assess their asthma control, current treatment, knowledge of and attitudes to asthma and barriers to achieving good control. Secondary objective is to develop interventions addressing identified barriers to good symptom control.
Each centre will undertake screening to identify 500 school children with asthma symptoms using questions from the Global Asthma Network’s questionnaire. Children identified to have asthma symptoms will fill in a digital survey, including: Asthma Control Test, questions on medication usage and adherence, medical care, the Brief-Illness Perception questionnaire and environmental factors. Exhaled nitric oxide testing and prebronchodilator and postbronchodilator spirometry will be performed. A subgroup of children will participate in focus group discussions. Results will be analysed using descriptive statistics and comparative analysis. Informed by these results, we will assess the feasibility of potential interventions, including the adaption of a UK-based theatre performance about asthma attitudes and digital solutions to improve asthma management.

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.

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.

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.

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.
