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.

A booklet on how CHWs were addressing eye health across Africa based on desk research and a survey in 23 countries
Governments have dedicated a pivotal role to the private sector in the implementation and financing of the 2030 Agenda and the SDGs. This has pushed a turn towards the private sector, the promotion of multi-stakeholder partnerships between public and private actors. However, far too often there is a... considerable gap between the social and environmental commitments companies make publicly in political fora like the UN and the actual effects of their production patterns and investment strategies on people and the environment. A new working paper, published by Brot für die Welt, Global Policy Forum and MISEREOR provides an overview of the ways and means by which the UN involves business actors in the debates around the implementation of the 2030 Agenda. It describes new initiatives and alliances of business actors around SDG implementation at the international level, and their main messages and policy proposals. With a few selected examples it contrasts the sustainability rhetoric of corporations with their business reality. And finally, the working paper draws conclusions and formulates recommendations for policymakers on how to increase the benefits of UN-business interactions in implementing the 2030 Agenda - and how to reduce associated risks and negative side effects.

Depression is a leading cause of non-fatal disease burden worldwide, with a lifetime prevalence of 9% among European adult men and 17% among European adult women.
The task at hand requires substantial investments in preventive mental health care, but the potential benefits can be equally rewarding.... After all, mental wellbeing is a key resource for learning, productivity, participation and inclusion. Investing in proactive care to promote, protect and sustain mental health in the population is therefore likely to offer good value for money.

Mental disorders impose an enormous burden on society, accounting for almost one in three years lived with disability globally. •In addition to their health impact, mental disorders cause a significant economic burden due to lost economic output and the link between mental disorders and costly, po...tentially fatal conditions including cancer, cardiovascular disease, diabetes, HIV, and obesity.•80% of the people likely to experience an episode of a mental disorder in their lifetime come from low- and middle-income countries.• Two of the most common forms of mental disorders, anxiety and depression, are prevalent, disabling, and respond to a range of treatments that are safe and effective. Yet, owing to stigma and inadequate funding, these disorders are not being treated in most primary care and community settings.

Methicillin-resistant Staphylococcus aureus(MRSA) strainsor multidrug-resistant S.aureus, initially described in 1960s,emerged in the last decade as a cause of nosocomial infections responsible for rapidly progressive, potential fatal diseases including life-threatening pneumonia, necrotizing fascii...tis, endocarditis, osteomyelitis, severe sepsis, and toxinoses such as toxic shock syndrome. A multifactorial range of independent risk factors for MRSA has been reported in literature and include immunosuppression,hemodialysis, peripheral malperfusion, advanced age, extended in-hospital stays, residency in long-term care facilities (LTCFs), inadequacy of antimicrobial therapy,indwelling devices, insulin-requiring diabetes, and decubitusulcers, among others.

Maternal mortality has fallen significantly in recent years, especially in countries that have emphasized the prevention of its main causes, such as hemorrhagic and infectious complications and hypertension , including in the Region of the Americas. In its final report on the Plan of Action to Accel...erate the Reduction of Maternal Mortality and Severe Maternal Morbidity, the Pan American Health Organization (PAHO) reported a continuing downward trend in maternal mortality, with an 18.1% reduction in the maternal morbidity ratio during the period 2010-2015 . From a pathophysiological perspective, death events are a common end result of a wide spectrum of complications leading to multi-organ dysfunction. However, there is a group of women in this situation who survive, despite the seriousness of their condition. This high number of patients––who were in serious condition
but did not die––reflects the actual health conditions in an institution or a country. For this reason, there is a need to create indicators to estimate morbidity in women due to diseases and incidents that occur during pregnancy, childbirth, and the puerperium. To this end, we propose conducting epidemiological surveillance of an indicator that includes women who survived after presenting a potentially fatal complication during pregnancy, childbirth, or the puerperium, reflecting quality medical attention and care (5, 6). This indicator
is maternal near-miss (MNM), which refers to extremely severe maternal morbidity––cases of a severity that
brings women very close to the death event. After adjusting the definition to a specific population and time,
MNM is defined as a case in which a woman nearly died, but survived a complication that occurred during
pregnancy, childbirth, or within 42 days of termination of pregnancy

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.

Leishmaniasis is a parasitic disease caused by intracellular protozoan parasites of the genus Leishmania (Trypanosomatidae family); it is endemic in more than 98 countries worldwide [1]. Visceral (VL) and cutaneous (CL) leishmaniasis are the most common forms of the disease. VL causes a systemic dis...ease characterised by fever, hepatosplenomegaly, anaemia and lymph node enlargement and may be fatal without appropriate treatment, while CL mainly causes skin ulcers and is considered a less severe form of the disease [2]. The incubation period for VL varies from 10 days up to nearly 3 years and for CL from 2 weeks to 3 years [3]. The natural route of transmission is a bite of blood-feeding phlebotomine sandflies; it may be zoonotic or anthroponotic, depending on the parasite species and the geographical location

Mycetoma is a specific chronic, granulomatous, inflammatory disease. It usually involves the subcutaneous tissue, most probably after traumatic inoculation of the causative organism. It has a prolonged, progressive, and indolent course, and, if untreated, it ultimately leads to destruction of the de...eper tissues and bone, resulting in deformity and disability that may necessitate amputation of the affected parts with all the social and economic implications of this. The disease is characterized by tumefaction, draining sinuses, and the presence of grains.

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 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 fatal but preventable viral disease. It can spread to people and pets if they are bitten or scratched by a rabid animal. In the United States, rabies is mostly found in wild animals like bats, raccoons, skunks, and foxes. However, in many other countries dogs still carry rabies, and most... rabies deaths in people around the world are caused by dog bites.

Rabies is a fatal viral disease, but is preventable in humans. The rabies virus is transmitted to humans through virus-laden saliva from a rabid animal, mostly dogs. The virus is shed in the saliva of an infected animal and can be introduced into another body through bites, scratches and any other ...wounds that transect the skin. Contact of the infected saliva with mucous membranes is also thought to be a possible route of infection, whereas contact of infected saliva with intact skin is not considered an exposure. Rabies is preventable through pre-exposure prophylaxis (PrEP) for individuals at high and continual risk, and post-exposure prophylaxis (PEP).

Rabies is a viral zoonotic disease that causes progressive and fatal inflammation of the brain and spinal cord. Clinically, it has two forms:
Furious rabies – characterized by hyperactivity and hallucinations.
Paralytic rabies – characterized by paralysis and coma.
Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

Rabies is a rare but serious infection that's usually caught from a bite or scratch of an infected animal. It's almost always fatal once symptoms appear, but vaccination and early treatment can prevent it.
Each year 1–2 million people are diagnosed with a tropical disease called leishmaniasis, which is caused by single-celled parasites. People are infected when they are bitten by sandflies carrying the parasite, and often develop skin lesions around the bite site. Though mild cases may recover on th...eir own or with treatment, sometimes the parasites multiply and spread elsewhere causing further skin lesions and facial disfigurement. Furthermore, the parasites can also infect internal organs such as the spleen and the liver, which without treatment can be fatal.

Leishmaniasis is a vector-borne tropical/subtropical disease caused by an intracellular parasite transmitted to humans by sand fly bite. It is endemic in Asia, Africa, the Americas, and the Mediterranean region. Worldwide reports include 1.5–2 million new cases each year, more than 300 million at ...risk of acquiring the disease, and 70,000 deaths per year. Clinical features depend on the Leishmania species and immune response of the host, varying from localized cutaneous disease to visceral form with potentially fatal outcome; however, the common presentation is either cutaneous, mucocutaneous, or visceral leishmaniasis. Many therapeutic agents are being used in Leishmania treatment, but the only effective treatment is achieved with current pentavalent antimonials. WHO considers Leishmaniasis as one of the “Neglected Tropical Diseases” that continues to be prevalent despite international, national, and local efforts towards its control and elimination over the last decade. This chapter reviews the global perspective of Leishmaniasis with increasing recognition of emerging “Atypical forms” and new surge of disease across the world mainly due to increasing conflicts in endemic areas leading to forced migration among other causes. All these challenges related to environment, disease, and vector pose major implications on WHO’s leishmaniasis control and elimination plan.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector...al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.
