The World Health Organization (WHO) is a specialized agency of the United Nations responsible for international public health. It is headquartered in Geneva, Switzerland, and has six regional offices and 150 field offices worldwide.
World AIDS Day, designated on 1 December every year since 1988, is an international day dedicated to raising awareness of the AIDS pandemic caused by the spread of HIV infection and mourning those who've died of the disease. The acquired immunodeficiency syndrome (AIDS) is a life-threatening condition caused by the human immunodeficiency virus (HIV). The HIV virus attacks the immune system of the patient and reduces its resistance to other diseases. Government and health officials, non-governmental organizations, and individuals around the world observe the day, often with education on AIDS prevention and control.
A healthy diet is a diet that maintains or improves overall health. A healthy diet provides the body with essential nutrition: fluid, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.
World Tuberculosis Day, observed on 24 March each year, is designed to build public awareness about the global epidemic of tuberculosis (TB) and efforts to eliminate the disease. In 2018, 10 million people fell ill with TB, and 1.5 million died from the disease, mostly in low and middle-income countries. This also makes it the leading cause of death from an infectious disease.
Global health is the health of the populations in the worldwide context; it has been defined as "the area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide". Problems that transcend national borders or have a global political and economic impact are often emphasized. Thus, global health is about worldwide health improvement, reduction of disparities, and protection against global threats that disregard national borders, including the most common causes of human death and years of life lost from a global perspective.
A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, heart diseases, cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others. NCDs may be chronic or acute. Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission.
World Diabetes Day (WDD) is the primary global awareness campaign focusing on diabetes mellitus and is held on 14 November each year.
Health care services in Nepal are provided by both public and private sectors and are generally regarded as failing to meet international standards. Prevalence of disease is significantly higher in Nepal than in other South Asian countries, especially in rural areas. Moreover, the country's topographical and sociological diversity results in periodic epidemics of infectious diseases, epizootics and natural hazards such as floods, forest fires, landslides, and earthquakes. But, recent surge in Non communicable diseases has emerged as the main public health concern and this accounts for more than two-thirds of total mortality in country. A large section of the population, particularly those living in rural poverty, are at risk of infection and mortality by communicable diseases, malnutrition and other health-related events. Nevertheless, some improvements in health care can be witnessed; most notably, there has been significant improvement in the field of maternal health. These improvements include:
Sudan is still one of the largest countries in Africa even after the split of the Northern and Southern parts. It is one of the most densely populated countries in the region and is home to over 37.9 million people.
The healthcare system in Turkey has improved in terms of health status especially after implementing the Health Transformation Program (HP) in 2003. "Health for All" was the slogan for this transformation, and HP aimed to provide and finance health care efficiently, effectively, and equitably. By covering most of the population, the General Health Insurance Scheme is financed by employers, employees, and government contributions through the Social Security Institution. Even though HP aimed to be equitable, after 18 years of implementation, there are still disparities between the regions in Turkey. While the under-5 mortality rate in Western Marmara is 7.9, the under-5 mortality rate in Southeastern Asia is two times higher than Western Marmara, with the rate of 16.3 in 2021.
World Hepatitis Day, observed on July 28 every year, aims to raise global awareness of hepatitis — a group of infectious diseases known as hepatitis A, B, C, D, and E — and encourage prevention, diagnosis and treatment. Hepatitis affects hundreds of millions of people worldwide, causing acute and chronic disease and killing close to 1.34 million people every year. Hepatitis can cause inflammation of the liver both acutely and chronically, and can kill a person. In some countries hepatitis B is the most common cause of cirrhosis and may also cause liver cancer.
World Blood Donor Day (WBDD) is held on June 14 each year. The event was organised for the first time in 2004, by four core international organizations: the World Health Organization, the International Federation of Red Cross and Red Crescent Societies; the International Federation of Blood Donor Organizations (IFBDO) and the International Society of Blood Transfusion (ISBT) to raise awareness of the need for safe blood and blood products, and to thank blood donors for their voluntary, life-saving gifts of blood. World Blood Donor Day is one of 11 official global public health campaigns marked by the World Health Organization (WHO), along with World Health Day, World Chagas Disease Day, World Tuberculosis Day, World Immunization Week, World Patient Safety Day, World Malaria Day, World No Tobacco Day, World Hepatitis Day, World Antimicrobial Awareness Week and World AIDS Day.
World Stroke Day is observed on October 29 to underscore the serious nature and high rates of stroke, raise awareness of the prevention and treatment of the condition, and ensure better care and support for survivors. On this day, organizations around the world have facilitated events emphasizing education, testing, and initiatives to improve the damaging effects of stroke worldwide. The annual event was started in 2006 by the World Stroke Organization (WSO) and the WSO declared stroke a public health emergency in 2010. The WSO now has an ongoing campaign that serves as a year-round interface for advocacy, policy, and outreach to support strides and continue progress made on World Stroke Day.
Diabetes mellitus, often known simply as diabetes, is a group of common endocrine diseases characterized by sustained high blood sugar levels. Diabetes is due to either the pancreas not producing enough insulin, or the cells of the body becoming unresponsive to the hormone's effects. Classic symptoms include thirst, polyuria, weight loss, and blurred vision. If left untreated, the disease can lead to various health complications, including disorders of the cardiovascular system, eye, kidney, and nerves. Untreated or poorly treated diabetes accounts for approximately 1.5 million deaths every year.
World Immunization Week is a global public health campaign to raise awareness and increase rates of immunization against vaccine-preventable diseases around the world. It takes place each year during the last week of April.
World Hearing Day is a campaign held each year by Office of Prevention of Blindness and Deafness of the World Health Organization (WHO). Activities take place across the globe and an event is hosted at the World Health Organization on March 3. The campaign's objectives are to share information and promote actions towards the prevention of hearing loss and improved hearing care. Any individual or organization can participate in various ways, by sharing campaign materials and organizing outreach actions. Examples are provided in the World Hearing Day annual activities reports. For participation to be recognized, one needs to register and report on their activity.
An outbreak of cholera began in Yemen in October 2016. The outbreak peaked in 2017 with over 2,000 reported deaths in that year alone. In 2017 and 2019, war-torn Yemen accounted for 84% and 93% of all cholera cases in the world, with children constituting the majority of reported cases. As of November 2021, there have been more than 2.5 million cases reported, and more than 4,000 people have died in the Yemen cholera outbreak, which the United Nations deemed the worst humanitarian crisis in the world at that time. However, the outbreak has substantially decreased by 2021, with a successful vaccination program implemented and only 5,676 suspected cases with two deaths reported between January 1 and March 6 of 2021.
