Global Health: 5 Major Issues You Should Know About

Article - Global Health 5 major issues you should know about
Global health, then, is the health of populations around the world. It encompasses a wide range of issues, from the spread of infectious diseases to the effects of pollution on public health.

Despite technological advancements in the health sector, we still face global health issues. The outbreak of COVID-19 has exposed our weaknesses that unfold these health issues. Basically, the more connected our world becomes, the more these health issues will proliferate.

The World Health Organization defines health as “a state of complete physical, mental, and social well-being – and not merely the absence of disease or infirmity.” Global health, then, is the health of populations around the world. It encompasses a wide range of issues, from the spread of infectious diseases to the effects of pollution on public health.

With such a large global impact, it’s important to be aware of the major health issues affecting people around the world. Here are five major issues surrounding global health that you should know about:

Climate Change:

Humans and the natural world are already feeling the effects of climate change. The Intergovernmental Panel on Climate Change (IPCC) warns that unless individuals and institutions take urgent action, the world will face increasingly severe and irreversible impacts, including rising sea levels, more extreme weather events, and dwindling supplies of fresh water.

These changes will significantly impact human health, both directly and indirectly. For example, hotter temperatures can lead to heat strokes and increased risk of wildfires, which can, in turn, cause respiratory problems.

Due to this issue, public health professionals have become an integral weapon in fighting these health issues arising from climate change. If you also want to become a public health professional, enrolling yourself in an MPH online program would be a valuable decision. This program will help you bring positive changes to your community and use your services to improve public health.

Noncommunicable diseases:

Noncommunicable diseases (NCDs) contribute significantly to the increasing rate of deaths and disabilities worldwide. They are responsible for nearly two-thirds of all deaths globally, making them a greater threat to public health than infectious diseases.

Long duration and slow progression characterize NCDs. They include conditions like heart disease, stroke, cancer, chronic lung disease, and diabetes. Many of these conditions are preventable, yet they continue to claim millions of lives each year.

NCDs are a growing problem in low- and middle-income countries. The burden of NCDs is greatest among the poor and marginalized, who often lack access to quality health care. NCDs are a complex problem; addressing them will require a multifaceted approach. But with committed action, we can dramatically reduce their effect.

Hesitation about vaccines:

Hesitation about vaccines is a major global health issue. According to a recent study, only 60% of people surveyed said they would get a vaccine if it were available. This hesitancy is a major concern for public health officials, as it could lead to a decrease in vaccination rates and an increase in the spread of disease.

There are many reasons why people may be hesitant to get vaccinated. Some may be concerned about the safety of vaccines, while others may not believe vaccines are effective. Whatever the reason, it is important to address these concerns and provide accurate information about the safety and efficacy of vaccines.

Vaccination is one of the most important tools we have to protect ourselves and our loved ones from disease. It is crucial that we work to increase vaccination awareness and address the hesitancy that surrounds this important issue.

Infectious Diseases:

Infectious diseases are responsible for millions of deaths each year, causing severe havoc even in highly developed countries. In recent years, several high-profile infectious disease outbreaks have occurred, such as COVID-19 and Ebola.

Pathogens, such as viruses, bacteria, and fungi, cause infectious diseases. These pathogens can spread from person to person, and they can also be spread by animals. The main cause of widespread infectious diseases is the globalization of the world. Infection from one part of the world easily spreads into another corner since traveling is much easier than ever.

There are a number of ways to prevent the spread of infectious diseases. These include vaccination, good hygiene practices, and prompt treatment of infected individuals. However, even with these measures, infectious diseases will always pose a threat to global health.

Agricultural practices:

A report by the World Health Organization has found links between poor agricultural practices and health problems such as malnutrition, food-borne illnesses, and waterborne diseases.

There are many reasons why poor agricultural practices are a major health issue. First, poor agricultural practices can lead to soil and water contamination. This can then lead to the contamination of food crops, which can put people at risk of exposure to hazardous chemicals. Second, poor agricultural practices can also lead to air pollution. This can be harmful to both people and the environment. Third, poor agricultural practices can lead to the depletion of natural resources. This can impact the environment and those who rely on those resources for their livelihood.


As the world becomes increasingly connected, our planet’s health becomes more important. A healthy environment is essential to keep viruses and diseases at bay. There are many global health issues that people should be aware of. They present a serious threat to global health, and we must work together to find solutions. By understanding these issues and what we can do to mitigate them, we can take steps to
