Top global health issues

The six global health issues detailed below help illustrate the breadth and depth of this complex field. Within the Platofrum9 Health pillar we will be breaking these and other issues down into specific Forums bringing together legal professionals active in this sector to discuss key issues.

1. Pandemics

Having just gotten through one, many are now very familiar with the devastating impact pandemics have. According to an article published in the Bulletin of the World Health Organizationpandemics are defined as global disease outbreaks. Examples of pandemics include certain influenza outbreaks, COVID-19, and other viral threats that reflect our vulnerability to widespread diseases—many of which originate in animals.

Every year, there are newly emerging pandemic threats. Vaccination efforts can help, but it’s critical to address issues at the source by addressing important areas like health education and responsible agricultural practices. Researchers have also made recommendations on global risk mitigation measures that can help even after an outbreak occurs.

2. Environmental factors

How can air pollution and climate change affect the health of the human population? In most cases, the answer lies in water sources and sanitation.

Storms, flooding, droughts, and air pollution make it easier for diseases to spread across large groups of people. The immediate solution is to provide resources like bottled water and sanitation technology, but global health must also focus on the prevention of environmental challenges in the first place.

“Climate change is thought by many global health experts to be the greatest threat to human health,” Dr. Macpherson says. “Global policies to mitigate mankind’s contribution to climate change are gaining traction.” 

He points to legislation in numerous countries as evidence of this. There are policies that regulate individual household energy consumption, for instance, as well as efforts to encourage large-scale industry progress toward environmentally conscious practices.

“Such changes will have profound health benefits for those who live in urban centers, which account for more than 50 percent of the world’s population,” Macpherson explains. This estimate aligns with data from The World Bank.

3. Economic disparities and access to health care

Despite relentless progress in the field of medicine, communities across the world still lack access to basic health education and health care. This results in health disparities, such as high infant mortality rates, which are often related to geography. Other disparities are the result of income inequality, with individuals and families simply unable to afford health care that is otherwise unavailable.

To solve these economic challenges, global health professionals and policy makers must explore opportunities to uplift underrepresented communities.

4. Political factors

Inadequate access to health care is exacerbated when international politics enter the mix. As conflicts within or between nations destroy critical infrastructure, average citizens become more vulnerable to diseases. This leads them to seek opportunities to flee the dangerous situations that threaten their well-beings.

Migration can allow illnesses to quickly spread, but organizations like the WHO stress that solutions should aim to improve refugee and migrant health through efforts like organizing across borders to endorse policies that bridge short-term humanitarian crisis responses with long-term health care access improvements.

5. Noncommunicable diseases

Heart disease, stroke, cancer, diabetes, and other noncommunicable diseases (NCDs) account for 70 percent of all deaths worldwide, according to the WHO.

Education plays a role in the prevention of NCDs, helping populations understand and change lifestyle factors, such as poor diets, inactivity, tobacco use, and alcohol consumption. But there is also a correlation between income level and the prevalence of NCDs.

The WHO notes that 85 percent of premature NCD-related deaths occur in low- and middle-income countries. Reducing the number of NCDs globally means reducing the factors that disproportionately arise in lower-income communities.

6. Animal health, food sourcing, and supply

Animal wellness is naturally intertwined with that of humans. Perhaps the clearest connection occurs within the food chain, but animals are also relied upon for transportation, draught power, and clothing in developing areas.

Agricultural practices, including irrigation, pesticide use, and waste management, can influence animal health, making disease transmission a concern at every stage of the food supply chain. With pathogens originating from animals or animal products playing such a significant role in disease transmission, veterinary medicine must be included in any effort to improve global health. Regulation and policy in this area will also be of key importance in the future.
