This brief update on tuberculosis (TB) in the African region covers the state of TB in the WHO African region, strategic priorities and targets and the impact of COVID-19 on essential services. This... is followed by key figures for the region, the role of WHO in country support and, recognizing the importance of diagnosis and drug susceptibility testing, a focus onstrengthening laboratory networks and the regional laboratory and diagnostic objectives. A brief update of the state of the science and how this is funded across the African region is provided, before closing with challenges and opportunities,strategic directions and a brief discussion of funding concerns. Discussions around the drivers of the disease, and issues of the poverty, inequality and stigma that continue to plague those living with TB are fully recognized, but are outside the scope of this report.

Reports of antimicrobial-resistant (AMR) microorganisms are increasing globally, threatening to render existing treatments ineffective against many infectious diseases. In Africa, AMR has already been documented to be a problem for human immunodefic...iency virus (HIV) and the pathogens that cause malaria, tuberculosis (TB), typhoid, cholera, meningitis, gonorrhoea and dysentery. Recognizing the urgent need for action, the 2016 United Nations (UN) General Assembly approved a resolution to ensure sustained and effective global action to address AMR.

The Practical manual on laboratory strengthening, 2022 update provides practical guidance on implementation of WHO recommendations and best practices for TB laboratory strengthening. It is an updated version of the GLI Practical Guide to Laboratory ...Strengthening published in 2017 and provides the latest practical guidance on use of newly recommended diagnostics as well as guidance in key technical areas, including quality assurance and quality management systems, specimen collection and registration, procurement and supply-chain management, diagnostic connectivity, biosafety, data management, human resources, strategic planning, and model algorithms. The key changes are:
inclusion of recent or updated WHO recommendations for tests to diagnose TB and detect drug resistance;
alignment with the latest WHO critical concentrations for phenotypic drug-susceptibility testing (DST) and the new definitions of pre-XDR-TB and XDR-TB;
updated information on building quality-assured TB testing and management capacity using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach (Score-TB package1);
updated information on assessing, analysing and optimising TB diagnostic networks; and
updated information on the use of next-generation sequencing (NGS) to detect mutations associated with drug resistance for surveillance purposes.
The document also provides references to resources and tools relevant for work on laboratory strengthening.

The goal of this addendum is to help management and staff
minimize the risk of TB transmission at facilities in resource limited settings in which a.) HIV-infected persons receive diagnosis, care, treatment,
and/or support, and b.) there is a ...high prevalence of HIV infection, both known
and undiagnosed, in settings such as prisons, jails, other
detention centers, and drug rehabilitation centers.

This study addresses part of the Terms of Reference for a scoping report ‘An analysis of approaches to laboratory capacity strengthening for drug resistant infections in low and middle income coun...tries’. It has been produced as a separate report because it is also very relevant for a second study ‘Supporting Surveillance Capacity for Antimicrobial Resistance: Regional Networks and Educational Resources’. This study compares antimicrobial surveillance systems in three low and middle income countries in order to describe the components of these systems and to understand which surveillance models are best suited to particular contexts. Ghana, Nigeria and Nepal were selected as study countries because they cover different continents and include one ‘fragile’ context (Nigeria). Brief information from Malawi is also included.

Of the 50 antibiotics in the pipeline, 32 target WHO priority pathogens but the majority have only limited benefits when compared to existing antibiotics. Two of these are active against the multi-drug res...istant Gram-negative bacteria, which are spreading rapidly and require urgent solutions.
Gram-negative bacteria, such as Klebsiella pneumoniae and Escherichia coli, can cause severe and often deadly infections that pose a particular threat for people with weak or not yet fully developed immune systems, including newborns, ageing populations, people undergoing surgery and cancer treatment.
The report highlights a worrying gap in activity against the highly resistant NDM-1 (New Delhi metallo-beta-lactamase 1), with only three antibiotics in the pipeline. NDM-1 makes bacteria resistant to a broad range of antibiotics, including those from the carbapenem family, which today are the last line of defence against antibiotic-resistant bacterial infections.

Barbados currently has a rudimentary framework and capacity to address the issue of antimicrobial resistance. There however needs to be coordination of efforts and improvement in areas where gaps have been identified.Actions required include improved antibiotic stewardship in healthcare settings, pr...evention of the spread of drug-resistant organisms//bacteria, elimination of the use of medically-important antibiotics for growth promotion in food animals, and expanded surveillance for drug-resistant bacteria in humans and animals.
The National Action Plan will provide the roadmap to guide Barbados in the effort to address the urgent and serious threat of AMR and will be organized around three goals for collaborative action.

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st century. The situation is deteriorating in many countries, particularly because of the synergy with t...he HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

The international community sits at the tipping pointof a post-‐antibiotic era, where common bacterial infections are no longer treatable with the antibiotic armamentarium that exists. In South Africa, t...he identification of the first case of pan-‐resistant Klebsiella pneumoniae(Brink et al, J Clin Microbiol. 2013;51(1):369-‐72) marks a watershed moment and highlights ourtip of the antibiotic resistance ‘iceberg’ in this country. Multi-‐drug resistant (MDR)-‐bacterial infections, predominantly in Gram-‐negative bacteria such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosaand Acinetobacter baumanniiare now commonplace in South African hospitals. Whilst a number of expensive new antibiotics for Gram-‐positive bacterial infections have been manufactured recently (some of which are licenced for usein South Africa), no new antibiotics active against Gram-‐negative infections are expected in the next 10-‐15years. Hence what we have now, needs conserving

Review of International, Regional and National Policies and Legal Frameworks that Promote Migrants and Mobile Populations' Access to Health and Malaria Services in the Greater Mekong Subregion (Cambodia, Lao People's Democratic Republic, Myanmar, Thailand and Viet Nam)
Migrants and mobile popul...ations face many obstacles in accessing equitable essential health care services due to factors such as living and working conditions, education level, gender, irregular migration status, language and cultural barriers, anti-migrant sentiments, and lack of migrant-inclusive health policies among others. Despite significant progress having been made in the context of malaria control in the Greater Mekong Subregion (GMS), human movements can impact malaria transmission patterns and potentially introduce drug-resistant parasites. This legal framework review therefore serves as a guidance document on approaches to address malaria and malaria elimination for migrant and mobile populations (MMPs) in five countries of the GMS.

Antimicrobial resistance (AMR) is an important public health concern shared by developed and developing countries. In developing countries the burden of infectious diseases is greater and exacerbated by limited access to, and availability and affordability of, antimicrobials required to treat infect...ions caused by AMR organisms. With drugs not listed on the essential drugs list (EDL), problems of increased morbidity, costs of extended hospitalisation and mortality are extremely serious. The problem of susceptibility to and spread of infections caused by multidrug-resistant (MDR) infectious agents is fuelled by factors such as limited access to clean water and sanitation to ensure personal hygiene, malnutrition, and the HIV/TB epidemic.
