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, caused by particular serovars of Chlamydia trachomatis, is the leading
infectious cause of blindness. Infection is transmitted within ocular and nasal secretions that are passed from person to person on fingers, fomites (such as clothing) and eye-seeking flies (particularly Musca sorbens)....
Ophthalmic infection is associated with an inflammatory conjunctivitis known as “active trachoma”. Repeated episodes of active trachoma can scar the eyelids. In some individuals this leads to trachomatous trichiasis (TT), in which one or more eyelashes on the upper
eyelid touch the eye. TT is extremely painful. It can be corrected surgically, but, if left untreated, may lead to corneal opacification, resulting in vision impairment and blindness.

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.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

Lymphatic filariasis (LF) infection if untreated results in fluid accumulation in the limbs or breasts (lymphedema) or genitalia (hydrocele) that is painful and causes great discomfort. Morbidity management and disability prevention (MMDP) strategies such as surgery for hydrocele, treatment of acute... attacks and management of lymphedema are necessary for the management of the advanced stages of LF. However, very few countries including Zambia, have adequate information on the health beliefs and health seeking behavior of communities living in endemic areas towards MMDP services for LF. This study sought to explore community and health provider perspectives towards MMDP services for LF in a highly endemic region, Luangwa District, Zambia, between February and April 2019.

To support its R&D activities on Chagas disease, DNDi launched the Chagas Clinical Research Platform (CCRP). The platform brings together partners, experts, and stakeholders to provide support for evaluation and development of new treatments for Chagas disease. The patient-centred platform aims to f...acilitate clinical research, provide a forum for technical discussions, develop a critical mass of expertise, and strengthen institutional research capacities. In addition, it identifies and reviews priority needs, works towards standardization of methodology to assess drug efficacy and reviews alternatives for using current approved drugs (new schemes, doses, combination) and special scenarios (resistance).

About six to seven million people worldwide, mostly in Latin America, are estimated to be infected with
Trypanosoma cruzi, the parasite that causes Chagas disease (WHO data from 2021). Chagas disease is
found mainly in endemic areas of 21 Latin American countries. Chagas disease was once entirely
...
confined to rural areas but in the last decades, due to population movements, most infected people live
in urban settings and the disease has spread to other continents. The burden of disease is due to its
chronic progression with people still suffering years later after initial infection.

Urogenital schistosomiasis is a common neglected tropical disease in many rural communities in African countries, with patches of infection in the Eastern Mediterranean Region. Globally, an estimated 239 million people are currently infected, with burden estimated at more than 3.5 million disability...-adjusted life years (DALYs). In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

Schistosomiasis is widely recognized as a disease that is socially determined. An understanding of the social and behavioural factors linked to disease transmission and control should play a vital role in designing policies and strategies for schistosomiasis prevention and control. To this must be a...dded the awareness that schistosomiasis is also a disease of poverty. It still survives in poverty-stricken, remote areas where there is little or no safe water or sanitation, and health care is scarce or non-existent. For a variety of complex reasons, many of which are addressed in this book, the disease is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural China. This concern for human behaviour in an environment of poverty echoes the concerns of the new research priority for “diseases of poverty” identified by the Special Programme for Research & Training in Tropical Diseases.

Epidemiological Update
Dengue
7 February 2020
Situation summary
In the Region of the Americas, between epidemiological week (EW) 1 and EW 521 of 2019, a total of 3,139,335 cases of dengue have been reported (321.58 cases per 100,000 population), including 1,538 deaths. Of the total cases, 1,367,...353 (43.6%) were laboratory-confirmed and 28,169 (0.9%) were classified as severe dengue. The case-fatality rate was 0.049%.

Schistosomiasis is an acute and chronic parasitic disease caused by blood flukes (trematode
worms) of the genus Schistosoma. At least 249 million people required preventive treatment in
2012. Preventive treatment, which should be repeated over a number of years, will reduce and
prevent morbidity.
The aim of this toolkit is to guide countries on how to best estimate their current burden of dengue by combining existing data from dengue surveillance systems with on-going research efforts to measure the community burden
of dengue.
This sourcebook aims to detail why health needs to be part of urban and territorial planning and how to make this happen. It brings together two vital elements we need to build habitable cities on a habitable planet: 1) Processes to guide the development of human settlements – in this document ref...erred to as “urban and territorial planning (UTP)”; and 2) concern for human health, well-being and health equity at all levels – from local to global, and from human to planetary health.
This sourcebook identifies a comprehensive selection of existing resources and tools to support the incorporation of health into UTP, including advocacy frameworks, entry points and guidance, as well as tools and illustrative case studies. It does not provide prescriptions for specific scenarios – these should be determined by context, people and available resources.
