Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

BMJ Global Health, Vol.5 No. 12Spatial subdivision of the camp (‘sectoring’) was able to ‘flatten the curve’, reducing peak infection by up to 70% and delaying peak infection by up to several months. The use of face masks coupled with the efficient isolation of infected individuals reduced t...he overall incidence of infection, and sometimes averted epidemics altogether. These interventions must be implemented quickly in order to be maximally effective. Lockdowns had only small effects on COVID-19 dynamics.
Conclusions
Agent-based models are powerful tools for forecasting the spread of disease in spatially structured and heterogeneous populations. Our findings suggest that feasible interventions can slow the spread of COVID-19 in a refugee camp setting, and provide an evidence base for camp managers planning intervention strategies. Our model can be modified to study other closed populations at risk from COVID-19 or future epidemics.

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.

Dengue is a mosquito-borne viral disease that has rapidly spread to all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes are also vectors of chikungunya, yellow fever and Zik...a viruses. Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

Chronic respiratory diseases, such as asthma and
chronic obstructive pulmonary disease, kill more than
four million people every year and affect hundreds
of millions more. These diseases erode the health
and well-being of the patients and have a negative
impact on families and societies. Women ...and
children are particularly vulnerable, especially those
in low and middle income countries, where they are
exposed on a daily basis to indoor air pollution from
solid fuels for cooking and heating. In high income
countries, tobacco is the most important risk factor
for chronic respiratory diseases, and in some of
these countries, tobacco use among women and
young people is still increasing.

Outbreaks of mpox in newly affected countries have mostly been identified in communities of gay, bisexual and other men who have sex with men who have had recent sexual contact with a new partner or partners. Communities of trans and gender diverse people linked to the same sexual networks have also... been affected.
This document (updated in March 2023) is intended for use by individuals, community leaders, influencers, health workers and others affected by or working on the mpox outbreak. It contains information to help people reduce their risk of mpox and to help slow the spread of the virus. This is the third version of this publication – it has been updated based on current public health advice.

Background: Community Health Workers (CHWs) have a positive impact on the provision of community-based
primary health care through screening, treatment, referral, psychosocial support, and accompaniment. With a
broad scope of work, CHW programs must balance the breadth and depth of tasks to mainta...in CHW motivation for
high-quality care delivery. Few studies have described the CHW perspective on intrinsic and extrinsic motivation to
enhance their programmatic activities.
Methods: We utilized an exploratory qualitative study design with CHWs employed in the household model in Neno
District, Malawi, to explore their perspectives on intrinsic and extrinsic motivators and dissatisfiers in their work. Data
was collected in 8 focus group discussions with 90 CHWs in October 2018 and March–April 2019 in seven purposively
selected catchment areas. All interviews were audiotaped, transcribed verbatim, coded, and analyzed using Dedoose.
Results: Themes of complex intrinsic and extrinsic factors were generated from the perspectives of the CHWs in
the focus group discussions. Study results indicate that enabling factors are primarily intrinsic factors such as positive
patient outcomes, community respect, and recognition by the formal health care system but can lead to the chal-
lenge of increased scope and workload. Extrinsic factors can provide challenges, including an increased scope and
workload from original expectations, lack of resources to utilize in their work, and rugged geography. However, a posi-
tive work environment through supportive relationships between CHWs and supervisors enables the CHWs.
Conclusion: This study demonstrated enabling factors and challenges for CHW performance from their perspec-
tive within the dual-factor theory. We can mitigate challenges through focused efforts to limit geographical distance,
manage workload, and strengthen CHW support to reinforce their recognition and trust. Such programmatic empha-
sis can focus on enhancing motivational factors found in this study to improve the CHWs’ experience in their role. The
engagement of CHWs, the communities, and the formal health care system is critical to improving the care provided
to the patients and communities, along with building supportive systems to recognize the work done by CHWs for
the primary health care systems.

La resistencia a los antimicrobianos (RAM, utilizado también como equivalente de "resistente a los antimicrobianos en este documento) constituye un importante motivo de preocupación mundial en el ámbito de la salud pública y un problema para la inocuidad de los alimentos. Cuando l...os patógenos se hacen resistentes a los agentes antimicrobianos, pueden ser más peligrosos para la salud humana a causa de un posible fracaso de los tratamientos, de la pérdida de opciones para los tratamientos y de la mayor probabilidad y gravedad de las enfermedades. Los problemas relacionados con la RAM están intrínsecamente relacionados con el uso de antimicrobianos en cualquier ámbito, lo que comprende los usos humanos y no humanos. El uso de agentes antimicrobianos en animales/cultivos destinados a la producción de alimentos constituye un factor potencialmente importante de riesgo de selección y propagación a los seres humanos de microorganismos resistentes y determinantes de RAM a partir de dichos cultivos/animales a través del consumo de alimentos.

Guiding the work of medica mondiale is an attitude of sensitivity towards both trauma and stress.
This stress- and trauma-sensitive approach has a strengthening and relieving effect on the affected
people and also the activists, specialist staff and working groups. For medica mondiale, trauma as a...
consequence of violence is not to be found exclusively in the area of (individual) psychology, but also
very significantly at the level of society and politics. For this reason, even a multi-sectoral approach
to supporting those affected by violence cannot stand alone: it must go hand in hand with measures
to bring about change in general political conditions, societal structures and public awareness.

Achieving the Sustainable Development Goals (SDGs) will require the international community to mobilize significant additional financing over the next decade. Tracking and analyzing this funding is central to measuring progress and making more informed choices to direct financial flows where they wi...ll have the greatest impact. This brief highlights AidData’s updated methodology to track financing to the SDGs, providing a baseline of funding for the years immediately before and after their launch. To track SDG-related financing, we build on our 2017 pilot methodology. Using data from the OECD CRS database on all official development assistance between 2010 and 2016, we identify individual projects that are linked to specific SDG goals or targets and then quantify total financing by SDG. This brief highlights four countries that represent different development contexts and trajectories, exploring how a country’s individual context impacts its SDG-related donor funding by examining the composition of funding and financing trends. We also look at SDG financing from the perspective of donors to see how their own interests are reflected in development portfolios across different countries.

Due to the heterogeneous distribution of malaria transmission and its determinants, subnational tailoring (SNT) provides an analytical framework to facilitate the targeting of each population with appropriate intervention packages for maximum impact to inform national strategic planning and prioriti...zation based on resources available. The WHO Global Malaria Programme recommends the use of subnational data on disease epidemiology and other relevant local contextual factors to facilitate the process of SNT. Once the strategies and intervention mixes have been defined, programmes can proceed to the prioritization of

space for health, the pursuit of efficiency gains and exploring innovative health financing for health seem attractive. This paper sought to synthesize available evidence on the nature of innovative health financing instruments, mechanisms and policies implemented in Africa. We further reviewed the factors that hinder or facilitate implementation, the lessons learnt on the structure, the development process and the implementation.

Challenges and Opportunities. This report presents a comprehensive assessment of the education and labor markets for nurses in the ECSA region. It documents the main challenges to train and deploy nurses and discusses opportunities for government and private sector employers to overcome these chall...enges. The report provides empirical evidence to support the expansion of nursing education within the region with a focus on private sector engagement, effective labor market regulation, and regional collaboration. A regional focus for investment may be necessary to create enough potential deals, reduce individual country and regulatory risks, encourage good private institutions to move across borders within the region, and seek to create regional standards for regulation.

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.

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.

The World Heart Federation (WHF) Roadmap series covers a large range of cardiovascular conditions. These Roadmaps identify potential roadblocks and their solutions to improve the prevention, detection and management of cardiovascular diseases and provide a generic global framework available for loca...l adaptation. A first Roadmap on raised blood pressure was published in 2015. Since then, advances in hypertension have included the publication of new clinical guidelines (AHA/ACC; ESC; ESH/ISH); the launch of the WHO Global HEARTS Initiative in 2016 and the associated Resolve to Save Lives (RTSL) initiative in 2017; the inclusion of single-pill combinations on the WHO Essential
Medicines’ list as well as various advances in technology, in particular telemedicine and mobile health. Given the substantial benefit accrued from effective interventions in the management of hypertension and their potential for scalability in low and middle-income countries (LMICs), the WHF has now revisited and updated the ‘Roadmap for raised BP’ as ‘Roadmap for hypertension’
by incorporating new developments in science and policy. Even though cost-effective lifestyle and medical interventions to prevent and manage hypertension exist, uptake is still low, particularly in resource-poor areas. This Roadmap examined the roadblocks pertaining to both the demand side (demographic and socio-economic factors, knowledge and beliefs, social relations, norms, and
traditions) and the supply side (health systems resources and processes) along the patient pathway to propose a range of possible solutions to overcoming them. Those include the development of population-wide prevention and control programmes; the implementation of opportunistic screening and of out-of-office blood pressure measurements; the strengthening of primary care and a greater focus on task sharing and team-based care; the delivery of people-centred care and stronger patient and carer education; and the facilitation of adherence to treatment. All of the above are dependent upon the availability and effective distribution of good quality, evidencebased, inexpensive BP-lowering agents.
