Nipah virus (NiV) is a zoonotic virus (it is transmitted from animals to humans) and can also be transmitted through contaminated food or directly between people. In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory ...illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers

Act 851 | AN ACT to revise and consolidate the law relating to public health to
prevent disease, promote, safeguard, maintain and protect the health
of humans and animals and to provide for related matters.
Antimicrobials are widely used in food animal production, and use is rapidly increasing.
In an era of growing demand for animal products, there is an increasing trend towards the industrial production of food animals, especially in lower- and middle-income countries (LMICs). One hallmark of this me...thod of animal production is the
use of antimicrobial drugs, which in the majority of cases are administered to healthy animals for purposes other than
treating or controlling disease (termed “therapeutic uses”)

Antimicrobial resistance is one of the most important threats to the health worldwide. Antimicrobial resistance or drug resistance is the reduction of the pharmaceutical effects of a drug against a disease or reduction of its effectiveness in improving the clinical signs of a disease. Antimicrobial ...resistance occurs naturally but misuse of antibiotics in human and animals significantly accelerates the process of developing antimicrobial resistance. In fact, antimicrobial resistance refers to the resistance of a microorganism to one or more antimicrobial drugs which had been previously sensitive to these drugs. Antimicrobial resistance can occur in a wide variety of pathogens including bacteria, parasites, viruses, fungi, and cancer cells and may threaten the life of every person, in every age, and in every country

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

Infectious diseases cause over one billion human infections per year, with millions of deaths each year globally. Extensive health and financial burden is seen from both established and emerging infectious diseases. Infectious diseases also affect plants and animals, which may pose threats to agricu...lture and water supplies with additional impacts on human health. This Question and Answers, prepared by the World Health Organization (WHO) and Convention on Biological Diversity (CBD) Secretariat under their joint work programme on biodiversity and health, and launched of the occasion of the International Day for Biodiversity 2020, summarizes some of the interlinkages between biodiversity and infectious diseases.
WHO is continuously monitoring and responding to the COVID 19 outbreak. This Q&A will be updated as more is known about COVID-19, how it is affecting people worldwide, and the effectiveness of interventions against the disease.

Antimicrobial resistance (AMR) threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi.
AMR occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to medicines making infections ha...rder to treat and increasing the risk of disease spread, severe illness and death. As a result, the medicines become ineffective and infections persist in the body, increasing the risk of spread to others.
Antimicrobials - including antibiotics, antivirals, antifungals and antiparasitics - are medicines used to prevent and treat infections in humans, animals and plants. Microorganisms that develop antimicrobial resistance are sometimes referred to as “superbugs”.

Transmission of many infectious diseases depends on interactions between humans, animals, and the environment. Incorporating these complex processes in transmission dynamic models can help inform policy and disease control int...erventions. We identified 20 diseases involving environmentally persistent pathogens (ie, pathogens that survive for more than 48 h in the environment and can cause subsequent human infections), of which indirect transmission can occur from animals to humans via the environment.

Monkeypox virus is an orthopoxvirus that causes human monkeypox, a viral disease with symptoms similar to smallpox, including fever and rash. Following the worldwide eradication of smallpox in 1980, monkeypox emerged as the most significant orthopoxvirus infection in humans. Cases are most often rep...orted from rural areas of Central and West African countries, particularly in regions close to tropical rainforest where people may have contact with infected animals. Someone can become infected through direct contact with respiratory droplets of another person who has monkeypox in the home or in a health facility, or with contaminated materials such as bedding. Although these are the main modes of person-to-person transmission, monkeypox outbreaks tend to occur in small clusters of a few cases without leading to widespread community transmission. For this reason, outbreaks can be easily controlled when responded to rapidly. On several occasions, monkeypox has been reported in other regions due to importation by travelers or infected animals. This course provides a general introduction to the disease through a video and accompanying downloadable presentation that can be reviewed at your own pace. It is intended for health personnel responsible for prevention and control of monkeypox, and for the general public.
The content and scope of this course on monkeypox have been tailored for outbreaks in African countries where the disease is endemic. The course material was last updated in 2020 and may not reflect most recent WHO guidance issued for the multi-country outbreak in 2022.

Leishmaniasis is a major vector-borne disease caused by obligate intramacrophage protozoa of the genus Leishmania, and transmitted by the bite of phlebotomine female sand flies of the genera Phlebotomus and Lutzomyia, in the old and new worlds, respectively. Among 20 well-recognized Leishmania speci...es known to infect humans, 18 have zoonotic nature, which include agents of visceral, cutaneous, and mucocutaneous forms of the disease, in both the old and new worlds. Currently, leishmaniasis show a wider geographic distribution and increased global incidence. Environmental, demographic and human behaviors contribute to the changing landscape for zoonotic cutaneous and visceral leishmaniasis. The primary reservoir hosts of Leishmania are sylvatic mammals such as forest rodents, hyraxes and wild canids, and dogs are the most important species among domesticated animals in the epidemiology of this disease. These parasites have two basic life cycle stages: one extracellular stage within the invertebrate host (phlebotomine sand fly), and one intracellular stage within a vertebrate host. Co-infection with HIV intensifies the burden of visceral and cutaneous leishmaniasis by causing severe forms and more difficult to manage. The disease is endemic to Ethiopia, and the clinical signs are not pathognomic. The visceral form (Kala-azar) may be confused with other similar conditions such as malaria, tropical splenomegaly, schistosomiasis, milliary tuberculosis, and brucellosis. Similarly, cutaneous leishmaniasis should be differentiated from disease like tropical ulcers, impetigo and leprosy. There are several methods of laboratory diagnosis of leishmaniasis, including parasitological, immunological and molecular. Different forms of treatments are available including oral, parenteral, and topical medications such as pentavalent antimonials, liposomal amphotericin B, miltefosine and paromomycin. Methods of control are largely limited to destruction of animal reservoirs, treatment of infected humans, and management of sand fly populations. Development of an effective vaccine against leishmaniasis has been largely unsuccessful and hinders its prevention.

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.

Rabies is a vaccine-preventable, zoonotic, viral disease affecting the central nervous system. Once clinical symptoms appear, rabies is virtually 100% fatal. In up to 99% of cases, domestic dogs are responsible for rabies virus transmission to humans. Yet, rabies can affect both domestic and wild an...imals. It spreads to people and animals via saliva, usually through bites, scratches or direct contact with mucosa (e.g. eyes, mouth or open wounds). Children between the age of 5 and 14 years are frequent victims.

Leishmaniasis is still considered to be a global health problem, which spreads in most countries in the world. Leishmania is an intracellular obligate protistan parasite that causes different clinical symptoms in infected humans and other animals. There are clinically different types of the disease ...including: visceral, cutaneous or muco-cutaneous leishmaniasis. Approximately, two million new infections occurring annually; 0.7 to 1.2 million cases are recorded with cutaneous leishmaniasis and 200,000–400,000 cases return for visceral leishmaniasis. However, Cutaneous leishmaniasis considers one of uncontrolled wobbling endemic diseases, especially in Iraq, which occurs at the skin to cause a dermal lesion. Usually, the lesion is spontaneously healed to leave a colorless depressed scar and permanent immunity.

Rabies remains an under-reported neglected zoonosis with a case-fatality rate of almost 100% in humans and animals. Dog-mediated human rabies causes tens of thousands of human deaths annually despite being 100% preventable. More than 95% of human cases are caused by the bite of a rabies-infected dog.... Dog-mediated human rabies disproportionately affects rural communities, particularly children, and economically disadvantaged areas of Africa and Asia, where awareness of the disease and access to appropriate post-exposure prophylaxis (PEP) can be limited or nonexistent.

Stopleishmania.org is an initiative of the VISAVET Health Surveillance Centre (UCM), the National Centre of Microbiology (ISCIII), the Animal Protection Centre (Madrid City Council) and the Directorate of Public Health (Regional Government of Madrid). This proj...ect launches the possibility of collaboration with other research centres, feeding the site with updated information on this disease.
Leishmaniosis prevention and control should include novel communication strategies that must be easily accesible and would include new advances in the knowledge of the disease. Recently, other animals different than dogs have been described as competent reservoirs of Leishmania, playing an important epidemiological role in recent outbreaks in Europe and Asia. At the moment, most of the information available is fundamentally devoted to humans and dogs, and there is no a global approach to the disease, taking into account all possible reservoirs.
The contents are available in Spanish and English, and come from the knowledge and experience in the disease of the above mentioned organisms, including research and information outreach.
The result is a website mainly focused on dissemination of the fundamental aspects for the control and prevention of the disease, taking into account that leishmaniosis due to its zoonotic condition, requires a multidisciplinary vision in accordance with the "One Health" principles. The web is complemented by a collaborative tool where the registered research groups can present themselves and disseminate their research results, therefore providing updated information on the scientific advances in the disease control.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.
