Takeaways

• 🌐 Global health is a public health approach focused on improving health for everyone worldwide and eliminating health equity gaps due to factors like nationality, income, and gender.
• 📈 The leading causes of death in most places are not communicable diseases like malaria or the flu, but rather non-communicable diseases such as cancer, heart disease, and diabetes.
• 🏛️ The World Health Organization (WHO) was established in 1948 with the goal of achieving the highest possible level of health for all peoples.
• 🌱 The eradication of smallpox in 1977 was a major success for the WHO and global health efforts, showcasing what can be achieved through coordinated international action.
• 💉 Communicable diseases, such as smallpox, HIV, polio, Ebola, and COVID-19, have been targeted by global health initiatives, though not all have been eradicated.
• 💼 Income level is a significant indicator of whether a country's leading cause of death is communicable or non-communicable, with non-communicable diseases being more prevalent in high-income nations.
• 📊 The burden of disease, measured in years of life lost, reflects the impact of communicable versus non-communicable diseases, with different patterns in high- versus low-income countries.
• 🚫 Aid dependency can be a short-term solution that may not address the deeper systemic issues that contribute to a country's health challenges.
• 🌾 The example of Haiti illustrates how historical events and foreign exploitation can lead to long-term dependency on aid and food insecurity.
• 🌱 Sustainable solutions to global health issues require addressing the root causes of poverty and injustice, not just providing immediate relief.

Q & A

What is the primary focus of global health?

Global health focuses on improving health for everyone in the world while eliminating health equity gaps that result from factors like nationality, income, and gender.

When was the World Health Organization (WHO) established and what was its primary objective?

The World Health Organization was established in April 1948, with the primary objective of attaining the highest possible level of health for all peoples.

What was the leading cause of global human death when the WHO was formed?

When the WHO was formed, the leading cause of global human death was communicable diseases, which are spread through pathogens like bacteria and viruses.

What was the WHO's approach to eradicating smallpox?

The WHO aimed to eradicate smallpox by ensuring that not a single person on Earth had the disease, so it could never be spread again. This was achieved through interventions, educational campaigns, and mass vaccinations.

Why are non-communicable diseases now the leading cause of death in most places?

Non-communicable diseases have become the leading cause of death in most places because as the rate of communicable diseases has decreased, these non-infectious diseases have made up a greater proportion of deaths.

How does a country's income level relate to the leading cause of death?

In high-income nations, non-communicable diseases generally account for around 80 percent of the disease burden, while in low-income nations, communicable diseases account for more than 60 percent of the burden.

What is the issue with relying on foreign aid for long-term solutions in countries like Haiti?

Foreign aid can lead to aid dependency and mask deeper systemic issues. In Haiti's case, cheap imported food makes it difficult for local farmers to compete, leading to less home-grown food and increased aid dependency.

Why did the Haitian government call for an end to international food aid in 2010?

The Haitian government called for an end to international food aid because it wanted to focus on developing infrastructure and workforce for sustainable economic growth, rather than just providing short-term food relief.

What are two areas where global health efforts have been consistently inadequate?

Two areas where global health efforts have been inadequate are mental health, which receives much less attention and funding than other forms of healthcare, and maternal health, where preventable causes still lead to a high number of deaths.

What is the importance of disease surveillance in global health?

Disease surveillance is crucial in global health as it involves the systematic gathering, analyzing, and interpreting of health data, making it accessible to everyone, which aids in early detection and response to health threats.

What ethical question does the field of public health grapple with regarding the concept of 'we'?

The field of public health grapples with the ethical question of who is included when referring to 'we', questioning whether it refers to a neighborhood, a country, or the entire world, especially when considering health as a shared global phenomenon.
