Mental health conditions affect one in 10 people at any one time and account for a large proportion of non-fatal disease burden. There is a high degree of comorbidity between mental health conditions such as depression and other noncommunicable diseases (NCDs), including cardiovascular disease, diab...etes and alcohol-use disorders. Mental disorders share common features with other NCDs, including many underlying causes and overarching consequences, their high interdependency and tendency to co-occur, and their predilection to being best managed using integrated approaches.

Fact Sheet, May 2018.
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

There are 3 main forms of leishmaniases: visceral (the most serious form because it is almost always fatal without treatment), cutaneous (the most common, usually causing skin ulcers), and mucocutaneous (affecting mouth, nose and throat).
Leishmaniasis is caused by protozoan parasites which are tra...nsmitted by the bite of infected female phlebotomine sandflies.
The disease affects some of the world’s poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system and lack of financial resources.
An estimated 700 000 to 1 million new cases occur annually.
Only a small fraction of those infected by parasites causing leishmaniasis will eventually develop the disease.

Leishmaniasis is a parasitic disease caused by the Leishmania parasite. This parasite typically lives in infected sand flies. You can contract leishmaniasis from a bite of an infected sand fly.
The sand flies that carry the parasite typically reside in tropical and subtropical environments. Fatal... epidemics have occurred in areas of Asia, East Africa, and South America.
Affected regions are often remote and unstable, with limited resources for treating this disease. Doctors Without Borders calls leishmaniasis one of the most dangerous neglected tropical diseases. The organization also states this disease is second only to malaria in parasitic causes of death.

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire...ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

Rabies is a zoonotic, vaccine-preventable viral disease that causes damage to the brain and spinal
cord in infected animals and humans. A zoonotic disease is a disease that can be transmitted
between animals and humans. Rabies is nearly 100% fatal once symptoms appear.
Rabies is an infectious viral disease that is almost always fatal once clinical symptoms appear.
In most cases, the disease is transmitted to humans by the bite of a rabid dog, but infection can also spread through scratches or via saliva.
Rabies kills one person every 9 minutes and children aged ...5–14 years are frequent victims.
Yet rabies is 100% vaccine preventable. Vaccinating dogs is the most cost-effective way to prevent rabies in people.
Education about dog behaviour, immediate care measures after a bite, responsible dog ownership and bite prevention are essential components of rabies elimination.
WHO and partners aim to achieve zero human rabies deaths by 2030.
The time to act is now.

In March 2018, a family and their sick puppy travelled through heavy rains in Malawi to a rabies vaccination drive. The puppy had bitten the family’s 12-year-old son, Isaiah Mzonda several days before and tested positive for rabies during the vaccination drive. Without appropriate prevention and t...reatment, rabies is fatal. Therefore, the rabies bite was a potential death sentence for the family’s young son who had not received any post-exposure treatment.

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.

Rabies is a viral infection of wild and domestic mammals, transmitted to humans by the saliva of infected animals through bites, scratches or licks on broken skin or mucous membranes.
In endemic areas (Africa and Asia), 99% of cases are due to dog bites and 40% of cases are children under 15 years... of age.
Before symptoms develop, rabies can effectively be prevented by post-exposure prophylaxis.
Once symptoms develop, rabies is fatal. There is no curative treatment; care is palliative.

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.

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 Africa, receives a high proportion of these patients, mostly tourists and expatria...te 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%.

Worldwide, there are about 17 million deaths due to cardiovascular disease (CVD) each year and at least two or three times as many non-fatal events. Raised cholesterol greatly increases the risks of stroke and heart disease, causing a large
health burden across the world. The World Health Organizat...ion has identified control of cholesterol as part of a Total Risk Approach to the prevention of CVD as a public health priority.

Cardiovascular disease is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is usually advanced by the time symptoms occur, genera...lly in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.

Cardiovascular diseases (CVDs) are a growing public health problem in Ghana and other African countries. Strokes and other CVDs have become a leading cause of death due to increasing risk factors such as hypertension. According to the Global Burden of Disease study (GBD), ischaemic heart disease was... the fourth leading cause of death in Ghana in 2016. The prevalence of hyper-
tension, a major risk factor for CVDs, is increasing rapidly and ranges from 19% to 48%, according to the Ghana Health Service Annual Report, 2017, due to rising life expectancy and the increasing prevalence of contributing factors such as overweight/obesity. Early diagnosis and adequate management of the risk factors can reduce the fatal consequences of CVDs.
At the heart of improving risk assessment and management of CVDs are nationally approved guidelines, which facilitate standardisation of care approaches.
These guidelines developed by experts from all levels of health care and stakeholders capture all recommended approaches and necessary information for clinicians and other healthcare workers on CVDs. They also serve as a practical guide for assessing and managing the most important CVDs prevalent in Ghana and can be used at all levels of care namely health facilities without a doctor; with a general practitioner and with a physician specialist.
