Why is Global Health Important?

What should drive global health research? In short, it should address the structural determinants of health, which contribute to global disparities in health. Changing entrenched systems can reduce the global burden of many diseases. For example, eradicating poverty could significantly reduce the burden of diseases that disproportionately affect the poor. Eliminating poverty would also be a necessary step to alleviate the enormous burden of many of the world's most pressing problems, including disease.

Noncommunicable diseases (NCDs) cause two-thirds of the world's premature deaths. They are most common in low and middle-income countries. According to the United Nations, the combined loss of noncommunicable diseases could cost $47 trillion by 2030. While NCDs may not be financially devastating for individuals, they can pose a serious health security challenge for governments and nations alike.

Although many of these diseases can be caused by genetic or behavioral factors, the burden of these conditions is significant and often overwhelms the response capacity of low-income countries. The increased burden of noncommunicable diseases on low-income countries has serious consequences for global stability and inequality. Noncommunicable diseases cause widespread illness and death and are a significant burden for the international community. The onset of an epidemic of noncommunicable diseases will likely increase global inequality and instability.

While the global health burden of noncommunicable diseases is increasing, the U.S. response is modest compared to other efforts to improve health around the world. The incidence of NCDs continues to increase while infectious diseases remain a serious health challenge. Some regions, such as Africa, are facing a double burden of disease. It's crucial to invest in NCD prevention and control to increase the quality of life and reduce the impact of these diseases.

Environmental challenges adversely affect human health and livelihood in OECD and non-OECD countries alike. These impacts are greatest among vulnerable groups. Improved air quality reduces the risk of respiratory diseases and pandemics, while better access to clean water improves health and lowers the risk of infectious diseases. In addition, effective waste management reduces the health risks of contaminated waste, while conservation and restoration of biodiversity improve human health.

Climate change causes extreme weather events that are contributing to a growing number of deaths and illnesses worldwide. High temperatures have been linked to an increase in mosquito populations and an increased risk of malaria. Rising temperatures increase the likelihood of asthma attacks, aggravate allergy symptoms, and cause premature death in many regions. Wildfire smoke contains high concentrations of toxic gasses such as carbon monoxide, nitrogen oxides, and volatile organic compounds, which can aggravate respiratory conditions and worsen chronic conditions such as asthma.

The social and environmental determinants of health affect many aspects of human health. Poverty, for example, contributes to health inequalities by increasing the likelihood of poor people suffering from illness and other health risks. The WHO has developed a commission to study the social and structural determinants of health, and its recommendations focus on ten core topics. These factors include nutrition, lifestyle, environment, and genetics.

Social, cultural, and economic conditions also play a major role in determining health. Inequities between different social groups and ages are indicative of health inequities. These differences are unfair and preventable. Furthermore, they are influenced by local, national, and global factors. It is therefore crucial to focus on these factors when planning health interventions. And by addressing these factors, governments and organizations can make improvements that will benefit populations worldwide.

Currently, discussions of preventing pandemics focus on what to do once the first victim has been infected. But the science shows that we can better protect our health by preventing pandemic pathogens before they infect humans or animals. Risky agricultural practices and deforestation are two major causes of spillover events, which push animals to new locations where the pathogens can enter new hosts.

This research builds upon previous research on pandemic preparedness, investigating the correlations between country-level preparedness and the likelihood of a pandemic occurrence. The authors also used indicators of government corruption and trust in science and government. This research has implications for health policy, as it shows that countries with higher levels of trust in their governments and communities tend to be better prepared to combat a pandemic than others.
