Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals 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.

For thousands of years, humans have been using wildlife for commercial and subsistence purposes. Wildlife trade takes place at local, national and international levels, with different forms of wildlife, such as live animals, partly processed products and finished products. Wildlife is a vital source... of safe and nutritious food, clothing, medicine, and other products, in addition to having religious and cultural value. Wildlife trade also contributes to livelihoods, income generation and overall economic development.
However, wildlife trade can have detrimental effects on species conservation, depleting natural resources, impoverishing biodiversity and degrading ecosystems (Morton et al., 2021). Wildlife trade, whether legal or illegal, regulated or unregulated, can pose threats to animal health and welfare. It also presents opportunities for zoonotic pathogens to spill over between wildlife and domestic animals, and for diseases to emerge with serious consequences for public or animal health and profound economic impacts (IPBES, 2020; Swift et al., 2007; Smith et al., 2009; Gortazar et al., 2014; Stephen, 2021; Stephen et al., 2022; FAO, 2020). The risk of pathogen spillover and disease emergence is amplified with increased interaction between humans, wildlife and domestic animals. The risk of pathogen spillover has also been exacerbated by climate change, intensified agriculture and livestock production, deforestation, and other land-use changes. Wildlife trade is also a risk to ecosystem biodiversity via the introduction of invasive species (Wikramanayake et al., 2021). Therefore, increased effort must be put into understanding the potential consequences of the wildlife trade, mapping and analysing the adjacent risks, and implementing strategies to manage those risks. Reducing wildlife-trade risks not only helps to limit disease but also minimises the negative effects of invasive species. Between 1960 and 2021, invasive alien species caused estimated cumulative damage of around 116 billion euros across 39 countries in the European Union alone, despite strict import regulations (Haubrock et al., 2021). The effect of invasive species is extremely apparent.

The pathway to strengthen multisectoral collaboration at the human-animal-environmental interface (HAI) aims to improve health security through One Health implementation. It outlines strategic guides and tools developed to support Member States through different steps of the HAI pathway.
The United Nations Environment Programme (UNEP) is stepping up its work on mapping zoonotic threat and protecting the environment to reduce the risk of future pandemics, such as the COVID-19 crisis currently sweeping the globe.
Rabies is entirely preventable, and vaccines, medicines, tools and technologies have long been available to prevent people from dying of dog-mediated rabies. Nevertheless, rabies still kills about 60 000 people a year, of whom over 40% are children under 15, mainly in rural areas of economically dis...advantaged countries in Africa and Asia. Of all human cases, up to 99% are acquired from the bite of an infected dog.

Rabies is a neglected zoonotic disease with a global burden of approximately 59,000 human deaths a year. Once clinical symptoms appear, rabies is almost invariably fatal; however, with timely and appropriate post-exposure prophylaxis (PEP) consisting of wound washing, vaccine, and in some cases rabi...es immunoglobulin (RIG), the disease is almost entirely preventable. Access to PEP is limited in many countries, and when available, is often very expensive.

Rabies is a devastating and societally important zoonotic disease, which is transmitted principally to humans through the bite of infected dogs. This acute, progressive viral encephalitis has the highest case fatality of any infectious disease and kills tens of thousands of people annually, with chi...ldren and impoverished communities being affected disproportionately.

Classical rabies caused by RABV occurs worldwide besides some isolated countries and Western Europe that are regarded rabies free. Carnivores, especially of the canidae family represent the principal reservoir species and are responsible for the maintenance of the infectious cycle and hence for the ...presence of the disease (see Epidemiology of rabies). While wildlife rabies maintained by different reservoirs hosts predominantly occurs in the Northern hemisphere, canine rabies is by far more important for public health in the developing world.

All lyssaviruses have evolved closely with distinct natural reservoir hosts. The latter are animals species in which a pathogen of an infectious disease are maintained independently. For lyssaviruses, these are a wide range of mammalian species within the Carnivora and Chiroptera (bats) orders with ...a global distribution.

For more than 100 years, the clearest route to elimination of dog-mediated rabies has been via mass vaccination of the animal hosts. It’s worked in plenty of countries. Still, in others, like India, which grapples with a third of the world’s rabies burden, large populations of free-roaming, hard...-to-track, often hard-to-reach dogs have made elimination an elusive goal.

Rabies is a fatal zoonotic disease most often transmitted to people via bites from infected dogs. This course provides a general introduction to rabies, and the One Health approach currently taken to prevent it. It consists of seven video-lectures, demonstration videos, and lessons learnt from peopl...e who work at the frontline of rabies elimination programmes around the world. It targets both a general audience and those who would like to learn more about rabies and the pathway to eliminating this disease – like prospective and current public health and animal health practitioners in rabies endemic countries.

World Rabies Day is the biggest event on the global rabies calendar, coordinated by GARC and it has been commemorated every year on September 28 – the anniversary of the death of Louis Pasteur – since 2007. World Rabies Day aims to raise awareness and advocate for rabies elimination globally. It... is an event designed to be inclusive, uniting people, organizations, and stakeholders across all sectors against rabies – because together we can eliminate rabies! With this concept of togetherness and unity in mind, the theme for this year’s World Rabies Day is: Rabies: One Health, Zero Deaths.

Human African Trypanosomiasis (HAT, sleeping sickness) and Animal African Trypanosomiasis (AAT) are neglected tropical diseases generally caused by the same etiological agent, Trypanosoma brucei. Despite important advances in the reduction or disappearance of HAT cases, AAT represents a risky reserv...oir of the infections. There is a strong need to control AAT, as is claimed by the European Commission in a recent document on the reservation of antimicrobials for human use. Control of AAT is considered part of the One Health approach established by the FAO program against African Trypanosomiasis. Under the umbrella of the One Health concepts, in this work, by analyzing the pharmacological properties of the therapeutic options against Trypanosoma brucei spp., we underline the need for clearer and more defined guidelines in the employment of drugs designed for HAT and AAT. Essential requirements are addressed to meet the challenge of drug use and drug resistance development. This approach shall avoid inter-species cross-resistance phenomena and retain drugs therapeutic activity.

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.

Chagas disease is caused by Trypanosoma cruzi, a protozoal organism primarily transmitted by triatomine insect vectors, also known as “kissing bugs.” It is a zoonotic disease originally described by Brazilian physician Dr. Carlos Chagas in 1909 and is widespread in Latin America. Although triato...mines and T. cruzi have long been endemic to the southern United States, awareness and identification of infected vectors and animals have recently increased throughout the United States. Canine Chagas disease can be acute or chronic and is predominantly characterized by inflammation and fibrosis of the heart, resulting in arrhythmias, myocardial dysfunction, heart failure, and sudden death, although many infected dogs are asymptomatic.
