There are 4 main forms of the disease: visceral leishmaniasis (VL, also known as kala-azar); post-kala-azar dermal leishmania...sis (PKDL); cutaneous leishmaniasis (CL); and mucocutaneous leishmaniasis (MCL). While cutaneous leishmaniasis is the most common form of the disease, visceral leishmaniasis is the most serious and can be fatal if untreated. Additionally, leishmaniasis can be classified as anthroponotic or zoonotic depending on whether the natural reservoir of the parasite is human or animal.
This report updates global epidemiological information on VL and CL to 2015, based on the main indicators published in the GHO, as of 1st September 2017.

Antimicrobial resistance has become one of the most eminent threats to global health and a rising concern for healthcare specialists. All around the world, many common infections are becoming resistant to the antimicrobial medicines used to treat them, resulting in high morbidity and mortality with ...serious social and economic implications. Additionally, there are few new antibiotics being developed but they are expensive and are not new classes. Antimicrobials are critical in the management of infectious diseases. They are also essential tools for protecting animal health and welfare, and contribute in production of safe food. Inappropriate use of antimicrobials can lead to resistance which is known as the antimicrobial resistance (AMR) resulting in high morbidity and mortality with serious social and economic implications.

En mai 2015, en adoptant le Plan d’action mondial pour combattre la résistance aux antimicrobiens (« Plan d’action mondial »), la Soixante-Huitième Assemblée mondiale de la Santé a reconnu l’importance de cette résistance en tant que problème majeur de santé publi...que. Le Plan propose des interventions pour lutter contre cette résistance, dont la réduction des usages inutiles d’antimicrobiens chez l’homme et chez l’animal. Il souligne aussi la nécessité d’une approche intersectorielle, « Un monde, une santé », pour endiguer cette résistance, impliquant des efforts de la part d’acteurs de nombreuses disciplines, dont les médecines humaine et vétérinaire

Antimicrobial resistance (AMR) is a growing threat to our health, causing at least 700,000 deaths globally every year. The death toll attributed to AMR is predicted to rise, with most lives lost in low and middle income countries (LMICs).
AMR is also a critical challenge for many other sectors, inc...luding animal health and welfare, aquaculture, agriculture, food safety and broader socioeconomic development. A coordinated, cross-sectoral and multi-pronged approach is needed at all levels of government to ensure an effective and targeted response to this mounting resistance.

Agriculture is highly exposed to climate change, as farming activities directly depend on climatic conditions. Agriculture also contributes to climate change through the release of greenhouse gases into the atmosphere. Two powerful greenhouse gases are by-products of agricultural activity:
Methan...e (CH4) – from livestock digestion processes and stored animal manure;
Nitrous oxide (N2O) – from organic and mineral nitrogen fertilisers.
However, agriculture can also contribute to climate change mitigation by reducing greenhouse gas emissions and by sequestering carbon while maintaining food production.

Overview
The aim of this guide is to support national immunization programme managers and others responsible for implementing human rabies vaccine programmes to:
inform policy discussions and operational planning for introducing or expanding rabies post-exposure prophylaxis (PEP) into a nationa...l immunization programme (e.g. through the national immunization programme, or other programmes); and
highlight considerations specific to rabies PEP for integration into existing systems, including for implementation, and monitoring and evaluation.
While the guide is mainly intended for programme managers and focuses on human vaccination, complementary animal health measures are highlighted where relevant given the zoonotic nature of rabies.
The guide was developed collaboratively with input from technical experts in rabies and immunization, vaccines and biologicals.

Neglected Tropical Diseases (NTDs) continue to cause hardship and harm to over one billion people worldwide, burdening individuals, families and communities who are already marginalized and disadvantaged. Taking a One Health approach that recognizes the relationship between human, animal, and enviro...nmental health is key to sustainably addressing NTDs. This course provides practical ideas, tools, and examples to enable each of us to take One Health action towards the global goal of substantially reducing the burden of NTDs by 2030.

Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

The control of schistosomiasis was a high priority in China soon after the founding of the People’s Republic of China in 1949, and schistosomiasis japonica was largely brought under control through 7 decades of effort. However, great challenges still exist to completely eliminate schistosomiasis f...rom the country by 2030 due to climate change, natural disasters, socioeconomic development, environmental protection, etc. The progress of the national schistosomiasis control program and the experience
accumulated over past several decades in China is reviewed in this article, and solutions to achieve the elimination of schistosomiasis through a One Health
approach are explored, which addresses complex health issues from a holistic perspective of human-animal-environment interaction.

Goal and objectives of the guideline
The goal of this guideline is to provide evidence-based recommendations to countries in their efforts to accomplish schistosomiasis morbidity control and elimination as a public health problem, and to move towards interruption of transmission.
The recommendatio...ns contained herein will help countries to implement national schistosomiasis control and elimination programmes and support efforts to verify the interruption of transmission.
The specific objectives are to provide guidance on:
prevalence thresholds, target age groups and frequency of preventive chemotherapy for schistosomiasis;
establishment of water, sanitation and hygiene (WASH) and snail control activities to support control and elimination of schistosomiasis;
use of diagnostic tests in humans in low transmission areas and for moving to, and evaluating the interruption of transmission of schistosomiasis;
tools for the assessment of Schistosoma spp. infection in snail hosts; and
diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs of infection

Schistosomiasis is an infectious disease caused by helminth parasites of the genus Schistosoma. Worldwide, an estimated 250 million people are infected with these parasites with the majority of cases occurring in sub-Saharan Africa. Within Asia, three species of Schistosoma cause disease. Schistosom...a japonicum is the most prevalent, followed by S. mekongi and S. malayensis. All three species are zoonotic, which causes concern for their control, as successful elimination not only requires management of the human definitive host, but also the animal reservoir hosts. With regard to Asian schistosomiasis, most of the published research has focused on S. japonicum with comparatively little attention paid to S. mekongi and even less focus on S. malayensis. In this review, we examine the three Asian schistosomes and their current status in their endemic countries: Cambodia, Lao People’s Democratic Republic, Myanmar, and Thailand (S. mekongi); Malaysia (S. malayensis); and Indonesia, People’s Republic of China, and the Philippines (S. japonicum). Prospects for control that could potentially lead to elimination are highlighted as these can inform researchers and disease control managers in other schistosomiasis-endemic areas, particularly in Africa and the Americas.

Foodborne trematode infections cause 2 million life years lost to disability and death worldwide every year.
People become infected by eating raw fish, crustaceans or vegetables that harbour the parasite larvae.
Foodborne trematodiases are most prevalent in East Asia and South America.
Foodborne ...trematode infections result in severe liver and lung disease.
Safe and efficacious medicines are available to prevent and treat foodborne trematodiases.
Prevention and management of food-borne trematodes requires cross-sectoral collaboration on the human-animal and ecosystems interface.

As of 14 December 2021, a total of 19 laboratory-confirmed human rabies cases has been reported in South Africa for 2021. The cases are from Eastern Cape, KwaZuluNatal and Limpopo provinces. In addition, four probable rabies cases were reported from KwaZulu-Natal and the Eastern Cape provinces. A pr...obable case of rabies is defined as a person who has had a history of contact with a suspected or confirmed rabid animal and has developed an acute encephalitis with hyperactivity and paralytic signs and symptoms that progressed and resulted in death, usually by cardiac or respiratory failure, typically within ten days.

Chikungunya fever (CHIKF) is an emerging infectious disease caused by an alphavirus transmitted by Aedes spp. mosquitoes. Because mosquito control programs are not highly efficient for outbreak containment, vaccines are essential to reduce the burden of disease. Although no licensed vaccine against ...CHIKF is yet available, many highly promising candidates are undergoing preclinical studies, and a few of them have been tested in human trials of phase 1 or 2. Here, we review recent findings regarding the need for a CHIKF vaccine and provide an update on vaccines nearing or having entered clinical trials. We also address needs to tackle bottlenecks to vaccine development—including scientific and financial barriers—and to accelerate the development of vaccines; several actions should be taken:
(i) design efficacy trials to be conducted during the course of outbreaks;
(ii) evaluate the opportunity for adopting the “animal rule”for demonstration of efficacy for regulatory purposes;
(iii) strengthen the collective commitment of nations, international organizations, potential donors and industry;
(iv) stimulate public and/or private partnerships to invest in vaccine development and licensure; and
(v) identify potential markets for an effective and safe CHIKF vaccine.

The previous report of the WHO Expert Committee on this disease
followed a meeting in 1995. Intensive, coordinated efforts against HAT during
the intervening 18 years have resulted in a decrease in incidence to a point at
which elimination is considered feasible. This report provides informati...on about
new diagnostic approaches, new therapeutic regimens and better understanding
of the distribution of the disease with high-quality mapping. The roles of human
and animal reservoirs and the tsetse fly vectors that transmit the parasites are
emphasized. The new information has formed the basis for an integrated strategy
with which it is hoped that elimination of HAT will be achieved. The report also
contains recommendations on the approaches that will lead to elimination of the
disease.
