Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeh...olders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from animals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

In 2012, the World Health Organisation (WHO) set out a roadmap for the control, elimination, or ...eradication of 17 neglected tropical diseases by 2020. Many were skeptical about the achievability of such goals. Now, still two years away from that end point, good news is emerging for gambiense human African trypanosomiasis (HAT), or sleeping sickness, caused by the tsetse-fly−transmitted protozoan parasite Trypanosoma brucei gambiense in West and Central Africa. The Rhodesiense form of the disease is being pursued under a separate programme.

Human African trypanosomiasis (HAT) is a lethal neglected tropical disease (NTD) transmitted by the bite of infected tsetse flies. The disease is also known as “sleeping sickness”. During the 20th century it caused enormous suffering in the endemic areas in sub-Saharan ...highlight medbox">Africa. HAT transmission last soared in the late 1990s, triggering a renewed, coordinated and very successful control effort. In this paper, we present achievements towards HAT elimination, with a focus on the WHO road map targets for 2020. In particular, reported cases continue to decline, from over 30,000 cases per year at the turn of the century to 663 cases in 2020. Despite the impact of the COVID-19 pandemic, HAT surveillance was largely sustained, and the network of health facilities able to diagnose and treat the disease further expanded. Looking to the future, the World Health Organization (WHO) set bold new targets for HAT in its 2021–2030 road map for NTDs, namely: the elimination of transmission of gambiense HAT, which occurs in western and central Africa, and the elimination as a public health problem of rhodesiense HAT, which is found in eastern and southern Africa. The strong commitment of national health authorities and the international community will be essential if these goals are to be achieved.

In Central and West Africa, regions together comprising 27 countries and 605 million people, the average person is exposed to particulate pollution levels that are more than 4 times the World ...class="attribute-to-highlight medbox">Health Organization’s (WHO) guideline of 5 μg/m³1. If these particulate pollution levels persist, average life expectancy in the regions would be 1.6 years lower, and a total of 971 million person-years would be lost, relative to if air quality met the WHO guideline. The Democratic Republic of the Congo, Rwanda and Burundi, are the top three most polluted countries in the region.

The control and elimination of schistosomiasis have over the last two decades involved several strategies, with the current strategy by the World Health O...rganization (WHO) focusing mainly on treatment with praziquantel during mass drug administration (MDA). However, the disease context is complex with an interplay of social, economic, political, and cultural factors that may affect achieving the goals of the Neglected Tropical Disease (NTD) 2021-2030 Roadmap. There is a need to revisit the current top-down and reactive approach to schistosomiasis control among sub-Saharan African countries and advocate for a dynamic and diversified approach.

Human schistosomiasis otherwise called bilharzia, is a fresh- water snail transmitted intravascular debilitating disease resulting from infection by the parasitic dimorphic Schistosoma trematode worms, which lives in the bloodstream of humans. The World...pan> Health Organization (WHO) regards the disease as a neglected tropical disease, with an estimated 732 million persons being vulnerable to infection worldwide in renowned transmission areas. Steinmann and co-workers documented that over 200 million individuals from Africa, Asia, and South America are infected with this disease. The WHO further estimated that schistosome infections and geohelminths accounts for over 40% of the world tropical disease burden with the exclusion of malaria. Humans get infected with this disease when they make contact with water contaminated with the skin-penetrating cercariae. Prevalence of schistosomiasis, at present, is still high in sub-Saharan Africa. In 2008, 17.5 million people were treated globally for schistosomiasis, 11.7 million of those from sub-Saharan Africa only. Approximately 120 million individuals in sub-Saharan Africa have schistosomiasis-related symptoms while about 20 million undergo hardship as a result of chronic presentations of the disease.

Internationally, there is a growing concern over antimicro-bial resistance (AMR) which is currently estimated to ac-count for more than 700,000 deaths per year worldwide. If no appropriate measures are taken to halt its pro-gress, AMR will cost approximately 10 million lives andabout US$100 trillion... per year by 2050. In contrast tosome other health issues, AMR is a problem that con-cerns every country irrespective of its level of incomeand development as resistant pathogens do not respect borders.Despite the threat presented by AMR, the 2014 WorldHealth Organization (WHO) and the recent O’Neill re-port describe significant gaps in surveillance, standardmethodologies and data sharing. The 2014 WHOreport identified Africa and South East Asia as the regions without established AMR surveillance systems.

With some 134,073,166 people living in endemic communities at risk of infection, Nigeria is the most endemic country in Africa and requires preventive chemotherapy (PC) for a total of 26.3 million persons. The National Schistosomiasis Elimination Pr...ogramme (NSCHEP), with the support of international partners, has been implementing PC in Nigeria since 2009 and most recently will need to revise its current strategy (Additional file 1). For example, the new World Health Organization (WHO) guideline has six key recommendations that will dramatically change the implementation of schistosomiasis elimination in endemic countries [3]. However, its impact and programmatic implications will vary from country to country, hence the need for a country-specific analysis. This article discusses these recommendations with specific reference to the challenges and opportunities in Nigeria. We summarise the key pointers in Additional file 1: Box 1 against the six recommendations of the WHO 2022 guideline.

Background: East African trypanosomiasis is an uncommon, potentially lethal disease if not diagnosed and treated in a timely manner. South Africa, as a centre for emergency medical evacuations from much of sub-Saharan ...ight medbox">Africa, receives a high proportion of these patients, mostly tourists and expatriate residents.
Methods: The cases of East African trypanosomiasis patients evacuated to South Africa, for whom diagnostic and clinical management advice was provided over the years 2004–2018, were reviewed, using the authors’ own records and those of collaborating clinicians.
Results: Twenty-one cases were identified. These originated in Zambia, Malawi, Zimbabwe, Tanzania, and Uganda. Nineteen cases (90%) had stage 1 (haemolymphatic) disease; one of these patients had fatal myocarditis. Of the two patients with stage 2 (meningoencephalitic) disease, one died of melarsoprol encephalopathy. Common problems were delayed diagnosis, erroneous assessment of severity, and limited access to treatment.
Conclusions: The key to early diagnosis is recognition of the triad of geographic exposure, tsetse fly bites, and trypanosomal chancre, plus good microscopy. Elements for successful management are rapid access to specific drug treatment, skilled intensive care, and good laboratory facilities. Clinical experience and the local stock of antitrypanosomal drugs from the World Health Organization have improved the chance of a successful outcome in the management of East African trypanosomiasis in South Africa; the survival rate over the period was 90.5%.
