The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

Improvements in water sanitation and hygiene (WASH) and wastewater management in all sectors are critical elements of preventing infections and reducing the spread of antimicrobial resistance (AMR) as identified in the Global Action Plan to combat AMR. Yet, at present, WASH and wastewater management... actors and improvement actions are under-represented in AMR multi-stakeholder platforms and national action plans (NAPs). This WHO/FAO/OIE technical brief on WASH and wastewater management to reduce the spread of AMR provides a summary of evidence and rationale for WASH and wastewater actions within AMR NAPs and sector specific policy to combat AMR. Evidence and actions are presented in the domains of; coordination and leadership, households and communities, health care facilities, animal and plant production, manufacturing of antimicrobials, and surveillance and research.

This document provides a decision-making framework for implementation of mass treatment interventions, active case-finding campaigns and population-based surveys for neglected tropical diseases in the context of the COVID-19 pandemic. A two-step approach is proposed: a risk–benefit assessment, to ...decide if the planned activity should proceed; and an examination of a list of precautionary measures that should be applied with the aim of decreasing the risk of transmission of COVID-19 associated with the activity, and strengthening the capacity of the health system to manage any residual risk. This guidance note is intended to health authorities, NTD programme managers and their supporting partners.

This paper explores access to water, sanitation, and health in pastoral communities in northern Tanzania. It argues that the concept of gender, used on its own, is not enough to understand the complexities of sanitation, hygiene, water, and health. It explores pastoralists’ views and perspectives ...on what is ‘clean’, ‘safe’, and ‘healthy’, and their need to access water and create sanitary arrangements that work for them, given the absence of state provision of modern water, sanitation, and hygiene (WASH) infrastructure. Although Tanzania is committed to enhancing its citizens’ access to WASH services, pastoral sanitation and hygiene tend to be overlooked and little attention is paid to complex ways in which access to ‘clean’ water and ‘adequate sanitation’ is structured in these communities. This paper offers an intersectional analysis of water and sanitation needs, showing how structural discrimination in the form of a lack of appropriate infrastructure, a range of sociocultural norms and values, and individual stratifiers interact to influence the sanitation and health needs of pastoralist men, women, boys, and girls.

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.

Schistosomiasis is a neglected tropical disease of global medical and veterinary importance. As efforts to eliminate schistosomiasis as a public health problem and interrupt transmission gather momentum, the potential zoonotic risk posed by livestock Schistosoma species via viable hybridisation in s...ub-Saharan Africa have been largely overlooked. We aimed to investigate the prevalence, distribution, and multi-host, multiparasite transmission cycle of Haematobium group schistosomiasis in Senegal, West Africa.

The Fifty-first World Health Assembly adopted resolution WHA51.11 in 1998, which targets the
global elimination of trachoma as a public health problem by 2020 (1). The strategy recommended
to achieve that goal is encapsulated by the acronym “SAFE”, which represents: Surgery for
individuals wi...th trachomatous trichiasis (TT; the late blinding stage of trachoma); and Antibiotics,
Facial cleanliness and Environmental improvement (2). The A, F and E interventions are delivered to
entire districts in which active (inflammatory) trachoma is common in order to treat ocular infection
with Chlamydia trachomatis, the causative organism of trachoma, and sustainably reduce its
transmission.

Fully functioning water, sanitation, hygiene (WASH) and health care waste management services are a critical aspect of infection prevention and control (IPC) practices, and ensuring patient safety and quality of care. Such services are also essential for creating an environment that supports the dig...nity and human rights of all care seekers, especially mothers, newborns, children and care providers.
WASH and waste services are also critical for preventing and effectively responding to disease outbreaks. The COVID-19 pandemic has exposed gaps in these basic services (Box 1). These gaps threaten the safety of patients and caregivers, and have environmental consequences, especially as a result of large increases in plastic health care waste. In short, WASH is a critical foundation for improving quality across the health system (1).
Many facilities lack plans and budgets for WASH, which has impacts on IPC. This lack of services, and of systems to improve them, compromises the ability to provide safe and quality care, and places health care providers and those seeking care at substantial risk of infection and loss of dignity. Unhygienic health care facilities without drinking water or functional toilets are also a disincentive to seeking care and undermine staff morale – these factors can have a critical impact on controlling infectious disease outbreaks.
Climate change and its impacts on WASH and health services, gender-specific needs, and equity in service provision and management all require rigorous attention, adaptable tools and regular monitoring.

sthma prevalence is increasing worldwide, and surveys indicate that most patients in developed and developing countries, including South Africa, do not receive optimal care and are therefore not well controlled. Standard management guidelines adapted to in-country realities are important to support ...optimal care. The South African Thoracic Society (SATS) first published a guideline for the management of chronic persistent asthma in 1992, which has subsequently been revised several times.
The main aim of the present document was to revise and update SATS’ statement on the suggested management of chronic asthma, based on the need to promote optimal care and control of asthma, together with the incorporation of new concepts and drug developments. This revised document reinforces optimal care and incorporates the following primary objectives to achieve the recent advances in asthma care:
• continued emphasis on the use of inhaled corticosteroids (ICS) as the foundation of asthma treatment
• to reduce the reliance on short-acting beta-2 agonist (SABA) monotherapy for asthma symptoms
• to incorporate the evidence and strategy for the use of the combination of an ICS and formoterol for acute symptom relief (instead of a SABA)
• to incorporate the evidence and strategy for the use of as-needed ICS-long-acting beta agonists (LABA) for patients with infrequent symptoms or ‘mild’ asthma
• to incorporate the evidence and strategy for the use of a long-acting muscarinic antagonist (LAMA) in combination with ICS-LABA; and
• to incorporate the evidence and strategy for the use of and management with a biologic therapy in severe asthma.
