Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga

s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

The WHO estimates that 19 million children aged 15 years or younger are visually impaired. Of these, 1.4 million are irreversibly blind and need visual rehabilitation interventions for full psychological and personal development. The remainder have visual problems that could be prevented or treated.

Identifying children with visual problems early in life so that they can benefit from medical and optical interventions remains a key challenge for most child eye health programmes. Reports from various low-and middle-income countries indicate that the age of children undergoing operation for cataract is frequently too high to achieve maximum benefit.

The World Health Organization (WHO) and the global community of countries, partners, donors, technical experts, scientists and field implementation teams continue to work towards the ultimate goal of a world free of the burden of neglected tropical diseases (NTDs).
Climate change presents the single biggest threat to human development, and its widespread impacts disproportionately burden the poorest and most vulnerable households in fragile and rural developing contexts – particularly women and children.
According to the Intergovernmental Panel on Climate C
...
hange’s (IPCC) latest report, ‘between 2010 and 2020, droughts, floods and storms killed 15 times as many people in highly vulnerable countries, particularly in Africa — which is responsible for less than 3 percent of global emissions – than in the wealthiest countries’.
Recognising environmental degradation and climate change are key accelerators of extreme child vulnerability, World Vision (WV) approved the Environmental Stewardship Management Policy (‘the Policy’) and Guidelines (‘the Guidelines’) in 2021.
To support the implementation of the Policy and Guidelines, WV has developed this Environmental Stewardship and Climate Action Handbook (‘the Handbook’) to help offices across the WV Partnership implement best practice environmental management strategies both in the field and in our operations and facilities.
Integrating environmental stewardship and climate action into all our work – whether that be in our Area Programmes, grant projects, responses to disasters or advocacy – is critical to achieving WV’s strategy.
As a Christian organisation we are compelled to follow the ways of Jesus Christ, calling us to care for the ‘least of these’ (Matthew 25:40) – the vulnerable children who are disproportionately impacted by climate change. Our response to the degradation of the environment is not motivated by political expediency or funding – but because we are called to steward God’s creation (Genesis 1:28).

Theodor Bilharz, a German professor of anatomy and chief of surgery at the Kasr El Ani Hospital of Cairo from 1850, first identified an infective organism, Distomum hematobium in 1851, which was renamed Schistosoma haematobium in 1858. It arose from a cestode worm, Hymenoleptis nana, lying in the sm

all colon of an Egyptian patient. He also discovered a trematode worm at the same time from an autopsy, thought to be the cause of urinary Schistosomiasis. Bilharz died from typhoid fever in 1862 at the age of 37. The Theodor Bilharz Research Institute in Giza, Egypt, stands as a tribute to him today. F. Milton published the first recorded peer-reviewed article report on Schistosomiasis in 1914.

The domestic regulation of public health emergencies (PHEs) is inextricably linked to the regulation of other types of disaster. PHEs are usually governed at least partly by general disaster and emergency laws. Moreover, there is significant overlap in the legal mechanisms used to respond to PHEs an

d other types of disaster, including the declaration of a state of disaster or emergency and the use of emergency powers. Even where PHEs are regulated by separate instruments, those instruments must surmount many of the same policy and practical challenges as general disaster laws, such as finely balancing competing considerations (e.g. speedy response versus due process), facilitating the coordination of a multitude of actors, and protecting the most vulnerable within society. Finally, many contemporary developments in disaster risk management (DRM), such as a greater emphasis on risk reduction and preparedness, are just as pertinent to PHEs as to other types of disaster.

ommunities. Medical teams working in armed conflict and other insecure environments
frequently face serious threats to their security and safety, challenges to patient access, and at times limited acceptance by affected communities in which they work and parties to the conflict. Such difficulties are likely to increase (6) and
thereby creating a critical need to establish contact and trust with all sides in conflicts and in other insecure environments to ensure operational continuity. This trust can best be achieved when all sides perceive the medical teams to be neutral, impartial, and independent, and specifically not aiding (or being perceived to aid) any one party to achieve a military, political or economic
advantage. For medical teams that are deploying increasingly closer to the frontlines, the implications of and consequences for both staff and patients of teams not being fully prepared, and/or not fully comprehending the context in which they work, can be severe. Medical response can easily be hindered or compromised by intentional or unintentional acts and the behaviour and

gh there is no unified consensus on the best measures to use for the public’s health and a nation’s epidemiologic situation, it is common for the disease burden to be measured by disease rates (incidence, prevalence, etc.), disease-specific death rates, comparative morbidity and mortality rates, geographic distribution, and disability-adjusted life years (DALYs). The current epidemiological situation, including data on disease rates or geographic distribution for the diseases in Table 1, is discussed below in Section 4. Hotez et al. (2008) were the first to review and compare the burden of DALYs in Latin America and the Caribbean—for NTDs, HIV/AIDS, malaria, and TB—as it existed about 10 years ago. Though the regional burden of TB, malaria, and neglected infectious diseases (NIDs) is somewhat less than it was 10 years ago, work (and schooling) continue to be lost to illness and premature death or disability, and the need for stepping up disease elimination efforts is evident in all communities living in vulnerable conditions....
