Countries, partners, and donors are committed to
the global elimination of blinding trachoma by 2020.
Achieving this public health milestone requires more
than funding; it requires health personnel with the
right mix of skills, and well supported and managed
health systems. Mass drug administra...tion (MDA)
with Zithromax®, the Pfizer, Inc. donated antibiotic,
is a key component of the SAFE strategy, endorsed
by the World Health Organization. There is growing
recognition that improving all aspects of MDA, from
planning to training, recording to reporting, and
receipt of drug to distribution (the supply chain), will
be necessary if MDA programmes are going to reduce
the community burden of Chlamydia trachomatis, and
eliminate trachoma as a cause of blindness by 2020.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

The sixteenth meeting of the Strategic and Technical Advisory Group for Neglected Tropical Diseases (STAG-NTD) was held as a hybrid meeting, 27–28 September 2022.
Dr Ren Minghui, Assistant Director-General, Universal Health Coverage/Communicable and Noncommunicable Diseases, welcomed participan...ts to the meeting. He said the World Health Organization’s Department of Control of Neglected Tropical Diseases (WHO/NTD) was in a state of transition. Following the death of the late esteemed Director Dr Mwelecele Ntuli Malecela earlier in the year, Dr Gautam Biswas had taken over as Acting Director but would soon retire; the appointment of a new Director was under way. Owing to rotation of STAG-NTD members, this would be the last meeting for some and the first meeting for several new participants. The work however would continue with the same commitment. Discussions over the next two days would focus on critical issues regarding recovery of NTD services following the disruptions caused by coronavirus disease (COVID-19), which had impacted many health services worldwide. He looked forward to receiving the advice and guidance of STAG-N

Trachoma is an eye infection that for thousands of years caused many people to go blind across all continents. As the result of development and targeted interventions, trachoma is now limited to an estimated 57 countries, often affecting the poorest
populations of the world. Today, more than 2 mill...ion people are either blind or suffer from a very painful disability as the result of trachoma.

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 la...test 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.

WHO needs US$2.54 billion to provide life-saving assistance to millions of people around the world facing health emergencies. WHO’s Health Emergency Appeal is a consolidation of WHO’s priorities and financial requirements for 2023 to carry out health interventions in emergency and humanitarian r...esponses. The number of people in need of humanitarian relief has increased by almost a quarter compared to 2022, to a record 339 million. WHO is responding to an unprecedented number of intersecting health emergencies: climate change-related disasters such as flooding in Pakistan and food insecurity across the Sahel in the greater Horn of Africa; the war in Ukraine; and the health impact of conflict in Yemen, Afghanistan, Syria and north eastern Ethiopia – all of these emergencies overlapping with the health system disruptions caused by the COVID-19 pandemic and outbreaks of measles, cholera, and other killers. Contributions to the appeal can be fully flexible, flexible across a region, or flexible within a country appeal.

The World Health Organization (WHO) and the global community of countries, partners, donors, technical experts, scientists and field implementation teams continue to work towards the ultimate goal of a world free of the burden of neglected tropical diseases (NTDs). This work is described in the NTD ...road map 2021–2030, WHO’s blueprint to drive global efforts in the fight against NTDs in the context of the United Nations Sustainable Development Goals. These goals encompass a vision of a world population for whom equality of opportunity and of health are fundamental.
Within this context, and during the two years since the launch of the road map (2021–2022), progress has been made. Nevertheless, hindrances towards achieving the targets for 2030 have arisen and work to overcome these obstacles continues. These endeavours have also revealed the scale of the task still facing the global NTD community.
Disruption as a result of the COVID-19 pandemic has continued to afflict longstanding and new programmes alike, while other entrenched issues have re-emerged in new and challenging ways. The global NTD community is also confronted with a changing, multi-dimensional funding landscape as donors reassess priorities and adapt to new ways of working, as well as a challenging and unpredictable international context. As a result, progress in controlling, eliminating or eradicating NTDs has not been as far-reaching as expected.

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Chagas disease (CD), caused by the parasite Trypanosoma cruzi, affects ~6–7 million people worldwide. Significant limitations still exist in our understanding of CD. Harnessing individual participant data (IPD) from studies could support more in-depth analyses to address the many outstanding resea...rch questions. This systematic review aims to describe the characteristics and treatment practices of clinical studies in CD and assess the breadth and availability of research data for the potential establishment of a data-sharing platform.

Dracunculiasis (Guinea worm disease), caused by the parasite Dracunculus medinensis, is traditionally acquired by drinking water containing copepods (water fleas) infected with D. medinensis larvae, but in recent years also appears increasingly to be transmitted by eating fish or other aquatic anima...ls. The worm typically emerges through the skin on a lower limb of the host 1 year after infection, causing pain and disability.

Countries are making progress toward the global goal of 95% of people living with HIV knowing their status by 2025. However, considerable gaps remain in achieving these goals globally. Men in high HIV burden settings and men from key populations in all settings are consistently less likely to know t...heir HIV status than women. Globally, 78% of men ages 15 years and older who are living with HIV are aware of their HIV status, compared with 86% of women with HIV of these ages.
Offering HIV testing services, including HIV self-testing, at formal and informal workplaces has emerged as an effective, acceptable and feasible approach for reaching men. A 2018 World Health Organization (WHO) and International Labour Organization (ILO) policy brief provides key guiding principles for HIVST implementation at workplaces. Building on the 2018 policy brief, this brief captures early experience with HIVST implementation at workplaces and discusses emerging approaches of sustainable financing that can be adapted for HIV self-testing at workplaces.
The primary audiences for this policy brief are ministries of health and labour, national HIV programmes, employers’ organizations, workers’ organizations (labour unions), enterprises, implementing partners, including civil society organizations, and health insurance agencies.

More than one million people each year become infected by parasites that cause the disease cutaneous leishmaniasis (CL). This disease manifests as one or more skin lesions or ulcers that are slow to heal with variable response rates to drug treatments. Thus far, little attention has been paid to how... the cultural effects of gender shape perceptions and experiences of CL. This review aims to bring together and analyse existing studies which use qualitative data to explore these differences. These studies offered insights into our specific research questions.

This perspective draws on the record of ancient pathogengenomes and microbiomes illuminating patterns of infectious disease over the course of the Holocene in order toaddress the following question. How did major changes inliving circumstances involving the transition to and intensification of farmi...ng alter pathogens and their distributions? Answers to this question via ancient DNA researchprovide a rapidly expanding picture of pathogen evolution and in concert with archaeological and historical data, give a temporal and behavioral context for heath in the past that is relevant for challenges facing the world today, including the rise of novel pathogens.
