Human African trypanosomiasis (HAT), also called sleeping sickness, is a parasitic infection that almost invariably progresses to death, unless treatment is provided. HAT caused devastating epidemics during the 20th century. Thanks to ...sustained and coordinated efforts during the past 15 years the number of reported cases has fallen to a historic low. Fewer than 3,000 cases were reported in 2015, and the disease is targeted for elimination by the World Health Organization. Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

The Leprosy Programme and Transmission Assessment (LPTA) is an activity that is carried out by internal teams towards the end of Phase 1 (see Leprosy Elimination Framework in the Annex) when a subnational jurisdiction (typically second-tier) reaches the milestone for interruption of transmission, i....e., zero autochthonous child cases for a consecutive period of five years. It also needs to be done at the end of Phase 2, when the second milestone of elimination of leprosy disease has been reached. An LPTA will be carried out to document that all relevant programme criteria have been met and examine trends of epidemiological indicators in such jurisdiction to confirm that the milestone has been achieved. The LPTA includes assessment of health facilities that provide leprosy services. LPTA comprises of review of epidemiological data, health facility assessment and data validation and verification of the programme criteria through observation during a field visit. The evidence collected in this way in subnational health administrative units is compiled in a Leprosy Elimination Dossier to be submitted to WHO when the country reaches the milestone for elimination of disease in the country as whole. Countries that have not detected any new leprosy cases in the past three years or more can use the LPTA at national level prior to or as part of the verification process. Countries likely to be among the first to apply for verification may have had no new cases detected for more than 10 years.

This facilitator’s manual is designed to support the implementation of the Dengue Clinical Management training course. The guide contains specific instructions for the facilitator and provides:
- a detailed description of the clinical course of dengue illness, which reflects the dynamic and sys...temic nature of dengue that has crucial bearing on the patient’s management;
- a detailed description of the basic pathophysiological changes of severe dengue (i.e. plasma leakage and hypovolaemia/shock) and guidance on the recognition of these changes and appropriate action of management;
- a brief discussion on WHO classification (1997) and its limitations;
- guidance on the differential diagnoses that can be confused with dengue or vice versa; they were described according to the stage of disease;
- a more focused guide on the disease monitoring in accordance with the dynamic changes as the disease progresses;
- emphasis on the importance of monitoring the plasma leakage (haemodynamic status of the patient, clinical signs of plasma leakage and haematocrit);
- a clearer algorithm for fluid management in cases of severe dengue; and
- emphasis on the importance of recognizing or suspecting significant occult bleed. Keep the facilitator’s manual with you each day as you prepare and deliver the information. Use it as a reference when delivering classroom presentations, but avoid reading directly from it during sessions.

Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

Snakebite envenoming is a neglected tropical disease (NTD) that is responsible for enormous suffering, disability and premature death on every continent. As over 5.8 billion people are at risk of encountering a venomous snake, it is not surprising but no less tragic that almost 7400 people every
da...y are bitten by snakes, and 220–380 men, women and children die as a result, adding up to about 2.7 million cases of envenoming and 8100–138 000 deaths a year.

Yaws, a neglected tropical disease (NTD) of the skin caused by the bacterium Treponema pallidum subspecies pertenue, is targeted in the latest WHO NTD Roadmap for eradication by 2030. In January, 2022, WHO published a manual that outlines the key activities that Ministries of Health in endemic count...ries should undertake to achieve this goal. The aim of the manual is to provide guidance on surveillance and evaluation of yaws as programmes progress towards eradication. However, yaws eradication in Africa faces several challenges.

In 1997, the Fiftieth World Health Assembly adopted resolution WHA50.29 on the elimination of
lymphatic filariasis as a public health problem. Preliminary guidance from WHO printed in 2011 referred to “verification” as the official process by which the achievements of the Global Programme to El...iminate Lymphatic Filariasis (GPELF) would be confirmed. For the sake of harmonization, the terminology now used for elimination of lymphatic filariasis as a public health problem is “validation”. In 2015, the WHO Strategic and Technical Advisory Group for Neglected Tropical Diseases endorsed standardized processes for confirming and acknowledging success for all neglected tropical diseases targeted for eradication, elimination of transmission, or elimination as a public health problem.

eLife 2020;9:e52072. The Triatominae are vectors for Trypanosoma cruzi, the aetiological agent of the neglected tropical Chagas disease. Their distribution stretches across Latin America, with some species occurring outside of the Americas. In particular, the cosmopolitan vector, Triatoma rubrofasci...ata, has already been detected in many Asian and African countries. We applied an ensemble forecasting niche modelling approach to project the climatic suitability of 11 triatomine species under current climate conditions on a global scale. Our results revealed potential hotspots of triatomine species diversity in tropical and subtropical regions between 21 ̊N and 24 ̊S latitude. We also determined the climatic suitability of two temperate species (T. infestans, T. sordida) in Europe, western Australia and New Zealand. Triatoma rubrofasciata has been projected to find climatically suitable conditions in large parts of coastal areas throughout Latin America, Africa and Southeast Asia, emphasising the importance of an international vector surveillance program in these regions.
