Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

In South and Central America, lymphatic filariasis (LF) is caused by Wuchereria bancrofti, which is transmitted by Culex quinquefasciatus, the only vector species in this region. Of the seven countries considered endemic for LF in the Americas in the last decade, Costa Rica, Suriname and Trinidad a...nd Tobago were removed from the World Health Organization list in 2011. The remaining countries, Brazil, Dominican Republic, Guyana and Haiti, have achieved important progress in recent years. Brazil was the first country in the Americas to stop mass drug administration (MDA) and to establish post-MDA surveillance. Dominican Republic stopped MDA in all LF-endemic foci: La Ciénaga and Southwest passed the third Transmission Assessment Survey (TAS) and the Eastern focus passed TAS-1 in 2018. Haiti passed the TAS and interrupted transmission in >80% of endemic communes, achieving effective drug coverage. Guyana implemented effective coverage in MDAs in 2017 and 2018 and in 2019 scaled up the treatment for 100% of the geographical region, introducing ivermectin in the MDA in order to achieve LF elimination by the year 2026. The Americas region is on its way to eliminating LF transmission. However, efforts should be made to improve morbidity management to prevent disability of the already affected populations.

The Western Pacific Region is the largest and most diverse region in the world, made up of 37 countries and territories in the Pacific, Oceania and parts of Asia, with a population of more than 1.9 billion people stretching over an area from China and Mongolia in the north to New Zealand in the sout...h. In 1999, 22 countries and territories in the Pacific joined together and launched the Pacific Programme to Eliminate Lymphatic Filariasis. Shortly after, the Global Programme to Eliminate Lymphatic Filariasis was launched in 2000. In 2004, 12 countries in the Asia subregion of the Western Pacific Region and Southeast Asian Region joined and developed the Mekong-Plus Strategic Plan for Elimination of Lymphatic Filariasis. Since then, significant efforts have been made by all endemic countries, with annual mass drug administration (MDA) as a principal strategy, through strong partnership with the WHO and other donors and partners. As a result, by the end of 2019, 10 of 22 endemic countries in the region, including 8 of 16 countries in the Pacific and 2 countries in the Asia subregion, achieved WHO validation for elimination of lymphatic filariasis (LF) as a public health problem. All the other countries are either progressing with post-MDA surveillance or accelerating efforts by adoption of the new triple drug therapy strategy and enhancement of MDA campaigns to tackle persistent transmission. Some 85% of the originally endemic implementation units have stopped MDA and the number of people requiring MDA for LF in the Western Pacific Region was reduced by 72% from 2000 to 2018. This paper reviews the progress, key success factors and remaining challenges and indicates the way forward to achieve LF elimination in the Western Pacific Region.

Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr...om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

The world is not on track to end the AIDS pandemic. New infections are rising and AIDS deaths are continuing in too many communities. This report reveals why: inequalities are holding us back. In frank terms, the report calls the world’s attention to the painful reality that dangerous inequalities... are undermining the AIDS response and jeopardising the health security of everyone. The report highlights three specific areas of inequality for which concrete action is immediately possible—gender
inequalities and harmful masculinities driving HIV; marginalisation and criminalisation of key populations, which our data show is resulting in starkly little progress for those populations and undermining the overall response; and
inequalities for children whose lives must matter more than their market share. But this is not a counsel of despair, it is a call to action. Through bold action to confront these inequalities, we can end AIDS.

This brief advocacy document highlights the burden, risks and prevention of injuries and violence, which took the lives of 4.4 million people in 2019 and constitute 8% of all deaths. Among the injury-related causes of death include road traffic crashes, dr...owning, falls, burns, poisoning and violence against oneself or others. For people age 5-29 years, three of the top five causes of death are injury-related, including road traffic injuries, homicide, and suicide. Injuries and violence are not evenly distributed across or within countries – some people are more vulnerable than others depending on the conditions in which they are born, grow, work, live and age; in general, being young, male and of low socioeconomic status all increase the risk of injury. This document, aimed at public health professionals; injury prevention researchers, practitioners and advocates; and donors, draws attention to specific strategies based on sound scientific evidence that are effective and cost-effective at preventing injuries and violence; it is critical that these strategies are more widely implemented.

Uganda hosts approximately 1.1 million refugees making it Africa’s largest refugee hosting country and one of the five largest refugee hosting countries in the world. Most recently, throughout 2016- 2018, Uganda was impacted by three parallel emergencies from South Sudan, the Democratic Republic o...f the Congo (DRC), and Burundi. In view of the on-going conflicts and famine
vulnerabilities in the Great Lakes Region, more refugee influxes and protracted refugee situations are anticipated in the foreseeable future. The unprecedented mass influx of refugees into Uganda in 2016-2018 has put enormous pressure on
the country’s basic service provision, in particular health and education services. Refugees share all social services with the local host communities. The refugee hosting districts are among the least developed districts in the country, and thus the additional refugee population is putting a high strain on already limited resources.

Atlas of African Health Statistics 2022: Health situation analysis of the WHO African Region
Since 2019, we have been implementing Phase 2 of the regional Transformation Agenda, which informs and aligns with the global WHO Transformation, to ensure WHO is accountable, ...light medbox">driven by re- sults and providing value for money in the pursuit of better health. Our global priority in this period is to contribute to delivering on the triple billion targets of expanding universal health coverage, protecting people from emergencies, and promoting health and well-being for people across the Region.
This year’s Atlas of African Health Statistics is being produced in the context of the COVID-19 pandemic that we have been expe- riencing for over two years. The ongoing coronavirus pandemic, together with other health emergencies in the WHO African Re- gion, is yet again testing the strength and resilience of our health systems. Indeed, the impact of COVID-19 is visible in the disruption of services. The report also presents the latest data for more than 50 health-related indicators of the Sustainable Development Goals and WHO’s “triple billion” targets and provides comprehensive country-level statistics using the results chain of the AFRO frame- work of actions for strengthening health systems to achieve UHC and the health-related SDGs.

Since 1996, trachoma has been targeted for elimination as a public health problem worldwide. The active trachoma criterion for national elimination as a public health problem is a TF1–9 < 5%, sustained for at least two years in the absence of antibiotic mass ...box">drug administration (MDA), in each formerly endemic EU. Using A, F and E, health ministries and their partners have made considerable progress towards achieving this criterion in formerly endemic EUs worldwide. In 2002, an estimated 1517 million people lived in EUs in which EU-wide implementation of the A, F and E components of SAFE were thought to be needed for the purposes of global elimination of trachoma as a public health problem; by June 2021, that number had fallen to 136.2 million, a 91% reduction. Approximately 85% of the 136.2 million people living in EUs needing A, F and E in June 2021 were in WHO’s African Region.

Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

This chapter discusses the antibacterial treatment of leprosy infections. Antibiotic treatment is
a key component of leprosy treatment, as it is vital to prevent the progression of the infection.
Treatment with rifampin and other antibiotics is highly effective and cures 98% of patients with
the ...leprosy infection. Furthermore, the relapse rate is very low, at about 1% over 5–10 years.
There is little M. leprae drug resistance in leprosy and few reports of multi-drug resistance (1, 2, 3,
4, 5, 6, 7, 8). An antibiotic treatment may take months or years to produce clinical improvement,
especially in patients with an initial high bacterial index (BI).

Human African trypanosomiasis (HAT), or sleeping sickness, is a painful and protracted disease transmitted through the bite of infected tsetse flies and it is found in rural parts of sub-Saharan Africa. Sleeping sickness has two clinical phases but this review focuses only on treatment of the second...-stage, which is characterized by neurological changes and almost invariably fatal without treatment. There are only a few drugs currently available for second-stage sleeping sickness, all with considerable adverse events and variable efficacy.
The review includes nine trials with 2577 participants. Each trial reported different comparisons of the drugs currently available to treat second stage HAT (melarsoprol, eflornithine, nifurtimox) so no meta-analysis was possible.

Human African trypanosomiasis is caused by Trypanosoma brucei gambiense in West and Central Africa and by T. brucei rhodesiense in East Africa; both species are endemic in Uganda. Trypanosoma brucei gambiense accounts for 98% of all cases of African trypanosomiasis, and T. brucei rhodesiense account...s for 2%. African trypanosomiasis has been targeted for eradication by the World Health Organization (WHO) and, as a result of control efforts, there has been a dramatic decrease (> 95%) in the number of reported cases worldwide.

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).

This was a Phase 3, multi-center, randomized, open-label, parallel-group, active control study where 273 male and female patients with first stage Trypanosoma brucei gambiense HAT were treated at six sites: one trypanosomiasis reference center in Angola, one hospital in South Sudan, and four hospita...ls in the Democratic Republic of the Congo between August 2005 and September 2009 to support the registration of pafuramidine for treatment of first stage HAT in collaboration with the United States Food and Drug Administration. Patients were treated with either 100 mg of pafuramidine orally twice a day for 10 days or 4 mg/kg pentamidine intramuscularly once daily for 7 days to assess the efficacy and safety of pafuramidine versus pentamidine. Pregnant and lactating women as well as adolescents were included.

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.
