India's population in 2021 as per World Bank is 1.39 billion. Being the world's most populous country and one of its fastest-growing economies, India experiences both challenges and opportunities in context of public health. India is a hub for pharmaceutical and biotechnology industries; world-class scientists, clinical trials and hospitals yet country faces daunting public health challenges like child undernutrition, high rates of neonatal and maternal mortality, growth in noncommunicable diseases, high rates of road traffic accidents and other health related issues.
In demography and medical geography, epidemiological transition is a theory which "describes changing population patterns in terms of fertility, life expectancy, mortality, and leading causes of death." For example, a phase of development marked by a sudden increase in population growth rates brought by improved food security and innovations in public health and medicine, can be followed by a re-leveling of population growth due to subsequent declines in fertility rates. Such a transition can account for the replacement of infectious diseases by chronic diseases over time due to increased life span as a result of improved health care and disease prevention. This theory was originally posited by Abdel Omran in 1971.
Health in Cuba refers to the overall health of the population of Cuba. Like the rest of the Cuban economy, Cuban medical care suffered following the end of Soviet subsidies in 1991; the stepping up of the US embargo against Cuba at this time also had an effect.
In Nigeria, there has been a major progress in the improvement of health since 1950. Although lower respiratory infections, neonatal disorders and HIV/AIDS have ranked the topmost causes of deaths in Nigeria, in the case of other diseases such as monkeypox, polio, malaria and tuberculosis, progress has been achieved. Among other threats to health are malnutrition, pollution and road traffic accidents. In 2020, Nigeria had the highest number of cases of COVID-19 in Africa.
In terms of available healthcare and health status Sierra Leone is rated very poorly. Globally, infant and maternal mortality rates remain among the highest. The major causes of illness within the country are preventable with modern technology and medical advances. Most deaths within the country are attributed to nutritional deficiencies, lack of access to clean water, pneumonia, diarrheal diseases, anemia, malaria, tuberculosis and HIV/AIDS.
Despite the significant progress Yemen has made to expand and improve its health care system over the past decade, the system remains severely underdeveloped. Total expenditures on health care in 2002 constituted 3.7 percent of gross domestic product.
Deficient sanitation systems, poor nutrition, and inadequate health services have pushed Haiti to the bottom of the World Bank's rankings of health indicators. According to the United Nations World Food Programme, 80 percent of Haiti's population lives below the poverty line. In fact, 75% of the Haitian population lives off of $2.50 per day. Consequently, malnutrition is a significant problem. Half the population can be categorized as "food insecure," and half of all Haitian children are undersized as a result of malnutrition. Less than half the population has access to clean drinking water, a rate that compares poorly even with other less-developed nations. Haiti's healthy life expectancy at birth is 63 years. The World Health Organization (WHO) estimates that only 43 percent of the target population receives the recommended immunizations.
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.
Although emphasized by the country's ruling Baath Party and improving significantly in recent years, health in Syria has been declining due to the ongoing civil war. The war which has left 60% of the population food insecure and saw the collapse of the Syrian economy, the surging prices of basic needs, the plummeting of the Syrian pound, the destruction of many hospitals nationwide, the deterioration in the functionality of some medical equipment due to the lack of spare parts and maintenance, and shortages of drugs and medical supplies due to sanctions and corruption.
The Tajikistan health system is influenced by the former Soviet legacy. It is ranked as the poorest country within the WHO European region, including the lowest total health expenditure per capita. Tajikistan is ranked 129th as Human Development Index of 188 countries, with an Index of 0.627 in 2016. In 2016, the SDG Index value was 56. In Tajikistan health indicators such as infant and maternal mortality rates are among the highest of the former Soviet republics. In the post-Soviet era, life expectancy has decreased because of poor nutrition, polluted water supplies, and increased incidence of cholera, malaria, tuberculosis, and typhoid. Because the health care system has deteriorated badly and receives insufficient funding and because sanitation and water supply systems are in declining condition, Tajikistan has a high risk of epidemic disease.
Iraq had developed a centralized free and universal healthcare system in the 1970s using a hospital based, capital-intensive model of curative care. The country depended on large-scale imports of medicines, medical equipment and even nurses, paid for with oil export income, according to a "Watching Brief" report issued jointly by the United Nations Children's Fund and the World Health Organization in July 2003. Unlike other poorer countries, which focused on mass health care using primary care practitioners, Iraq developed a Westernized system of sophisticated hospitals with advanced medical procedures, provided by specialist physicians. The UNICEF/WHO report noted that prior to 1990, 97 percent of the urban dwellers and 71 percent of the rural population had access to free primary health care; just 2 percent of hospital beds were privately managed.
Healthcare in Laos is provided by both the private and public sector. It is limited in comparison with other countries. Western medical care is available in some locations, but remote areas and ethnic groups are underserved. Public spending on healthcare is low compared with neighbouring countries. Still, progress has been made since Laos joined the World Health Organization in 1950: life expectancy at birth rose to 66 years by 2015; malaria deaths and tuberculosis prevalence have plunged; and the maternal mortality ratio (MMR) has declined by 75 percent.
In precolonial Ghana, infectious diseases were the main cause of morbidity and mortality. The modern history of health in Ghana was heavily influenced by international actors such as Christian missionaries, European colonists, the World Bank, and the International Monetary Fund. In addition, the democratic shift in Ghana spurred healthcare reforms in an attempt to address the presence of infectious and noncommunicable diseases eventually resulting in the formation of the National Health insurance Scheme in place today.
The quality of health in Cambodia is rising along with its growing economy. The public health care system has a high priority from the Cambodian government and with international help and assistance, Cambodia has seen some major and continuous improvements in the health profile of its population since the 1980s, with a steadily rising life expectancy.
Health problems have been a long-standing issue limiting development in the Democratic Republic of the Congo.
Health in Angola is rated among the worst in the world.
A landlocked sub-Saharan country, Burkina Faso is among the poorest countries in the world—44 percent of its population lives below the international poverty line of US$1.90 per day —and it ranks 185th out of 188 countries on UNDP's 2016 Human Development Index. Rapid population growth, gender inequality, and low levels of educational attainment contribute to food insecurity and poverty in Burkina Faso. The total population is just over 20 million with the estimated population growth rate is 3.1 percent per year and seven out of 10 Burkinabe are younger than 30. Total health care expenditures were an estimated 5% of GDP. Total expenditure on health per capita is 82 in 2014.
Health in South Africa touches on various aspects of health including the infectious diseases, Nutrition, Mental Health and Maternal care.
Hospitals and small medical centers and posts are found throughout the island of Madagascar, although they are concentrated in urban areas and particularly in Antananarivo. In addition to the high expense of medical care relative to the average Malagasy income, the prevalence of trained medical professionals remains extremely low.
