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.

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

These guidelines have been prepared by the Sub directorate: Maternal Health for the guidance of health workers (doctors and midwives) providing obstetric, surgical and anaesthetic services for pregnant women in district clinics, health centres and district hospitals. These guidelines are intended fo...r use in clinics, community health centres and district hospitals where specialist services are not normally available. The guidelines deal mainly with the diagnosis and especially the management of common and serious pregnancy problems. The assumption is made that the reader has a basic knowledge and understanding about the care of pregnant women. With a few exceptions (e.g. pre-eclampsia), there is no mention of aetiology and pathogenesis of the conditions described.https://www.knowledgehub.org.za/elibrary/guidelines-maternity-care-south-africa-2016

The World Health Organization recently redefined leprosy elimination as a phased process, with the first milestone being the
interruption of transmission, achieved when no new child cases (defined as younger than 15 years) are reported for five consecutive years.
In Pakistan, the well-functioning ...leprosy programme, with effective case management, context-specific active case-finding strategies and
a robust data management system, has contributed to a decrease in new cases. Between 2001 and 2023, new adult cases dropped by 75%
(from 878 cases to 220 cases annually) and child cases by 83% (from 93 to 16). To support the country’s goal of no new child cases by 2030
and ultimately eliminate the disease, the nongovernmental organizations Marie Adelaide Leprosy Centre and Aid to Leprosy Patients, with
support from the German Leprosy and Tuberculosis Relief Association, have developed a zero leprosy roadmap. As part of this roadmap,
the leprosy elimination strategy emphasizes improving active case-finding and providing post-exposure prophylaxis for contacts of leprosy
cases, who are at the highest risk

Dengue is the world’s most important arboviral disease in terms of number of people affected. Over the past 50 years, incidence increased 30-fold: there were approximately 390 million infections in 2010. Globalization, trade, travel,... demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

The IFRC Psychosocial Centre has published a guidance note providing an overview of the psychosocial consequences of virus outbreaks, with a focus on mpox, and outlines key considerations for MHPSS programming.
The current mpox outbreaks present numerous challenges for responding National Societi...es. A key issue is addressing stigma as individuals infected, or suspected of having mpox may experience social ostracization, discrimination, and even violence. In many African communities, where cultural and social norms are vital to community health, considering the cultural and psychosocial implications of virus outbreaks is integral for effective disease management. In addition, Red Cross Red Crescent staff and volunteers may be personally exposed and working in complex environments with rumours and misinformation generating fear and anxiety. This guidance addresses the key mental health and psychosocial support implications of the ongoing mpox crisis.
Guleed Dualeh, MHPSS Advisor
This guidance note is intended for Red Cross Red Crescent National Societies and IFRC departments who may be responding to mpox in their country, or region. It includes guidance on:
Common reactions and behaviours in epidemics
Caring for staff and volunteers in health emergencies
Integration of MHPSS considerations for into health responses

Some observers have described the coronavirus pandemic as an 'Anthropocene disease,' thereby highlighting its connection with this new ecological era that is characterised by the considerable pressure human activities are exerting on ecosystems and the consequences on public health, society and the ...environment. This article focuses on the recent emergence of the 'Planetary Health' paradigm. Launched by the Rockefeller Foundation and the medical journal The Lancet, Planetary Health is one of the most ambitious attempts in recent years to systematize global health in the Anthropocene. While recognising the interest and necessity of reflecting on human health and the health of the planet, this article aims to show, however, that the Planetary Health paradigm is problematic and aporetic for two reasons. First, because it is based on a scientistic and depoliticised conception of the Anthropocene, which obscures capitalism's responsibility for the contemporary global and, especially, ecological crisis. Second, because this conception leads to a promotion of solutions that are essentially based on the financialization and technoscientific management of the living world - precisely the underlying cause of the degradation of ecosystems and living conditions that created the Anthropocene in the first place. A different kind of 'planetary health' remains possible and desirable.

Haiti, one of the poorest countries in the world, was devastated by an earthquake in 2010. The disaster uncovered the realities of a non-existent mental health care system with only ten psychiatrists nationwide. Attempts were made to assess the increased prevalence of mental illness, likely due to t...he trauma to which many were exposed. Several interventions were carried out with aims to integrate mental health into primary health care services. The interplay between socio-cultural beliefs and health (both mental and physical) in Haiti has been widely commented upon by both foreign aid and local caregivers. Observations frequently highlight barriers to the willingness of patients to seek care and to their acceptance of biomedicine over traditional Vodou beliefs. The perception of Haitian beliefs as barriers to the availability and acceptance of mental health care has intensified the difficulty in providing effective recommendations and interventions both before and after the earthquake. Argued in this review is the importance of considering the interactions between socio-cultural beliefs and mental health when developing models for the prevention, screening, classification and management of mental illness in Haiti. These interactions, especially relevant in mental health care and post-disaster contexts, need to be acknowledged in any healthcare setting. The successes and failures of Haiti’s situation provide an example for global consideration.

Masangane Case Study
The Vesper Society commissioned ARHAP to do research on the integrated Masangane HIV/AIDS programme affiliated with the Moravian Church in Eastern Cape, South Africa. Completed in 2006, this study aimed to understand the role of the religious health assets of the Masangane ART ...programme for public health, as a model for a replicable response to HIV/AIDS. A crucial aspect of this research involved teasing out what value is added to this programme by its faith-based nature. Field work for this case study consisted of more than 20 key informant interviews of various stakeholders: Masangane staff and management; church leaders; health seekers; donors and health providers. Health seekers also answered 77 questionnaires and were involved in two focus groups.
