Introduction to Global Health
Global health refers to the health of populations in a global context and transcends the perspectives and concerns of individual nations. It encompasses a wide range of health issues, including infectious diseases, non-communicable diseases, healthcare access, and public health initiatives.
This page aims to provide a comprehensive overview of global health trends through data-driven stories, visualizations, and references to reputable sources. Understanding these trends helps inform policy-making, resource allocation, and global health initiatives.
Infectious Diseases
Infectious diseases remain a major global health challenge, impacting millions of lives each year. Here, we explore the trends and impacts of key infectious diseases.
HIV/AIDS Prevalence and Incidence (1990-2023)
This graph depicts the prevalence and incidence of HIV/AIDS from 1990 to 2023. The prevalence line shows the total number of people living with HIV/AIDS, while the incidence line indicates the number of new cases each year. The slight decline in both prevalence and incidence over time suggests improvements in prevention, treatment, and awareness efforts globally.

Non-Communicable Diseases (NCDs)
Non-communicable diseases, including heart disease, diabetes, and cancer, are the leading causes of death globally. Here, we examine the trends and regional differences in the prevalence of these diseases.
Heart Disease Mortality (2000-2023)
This graph displays the mortality rates of heart disease from 2000 to 2023. The steady increase highlights the growing burden of cardiovascular diseases globally, driven by factors such as aging populations, unhealthy diets, and sedentary lifestyles.

Diabetes Prevalence (2000-2023)
This bar chart illustrates the rising prevalence of diabetes from 2000 to 2023. The increase is driven by lifestyle changes, including poor diet and lack of physical activity, as well as genetic factors. Addressing diabetes requires comprehensive public health strategies focusing on prevention, early detection, and effective management.

Healthcare Access and Quality
Access to quality healthcare varies significantly across the globe, influenced by factors such as geography, socio-economic status, and infrastructure. Here, we explore these disparities and their impacts on health outcomes.
Global Healthcare Access Index (2023)
This map represents the healthcare access index for various countries in 2023. The index measures the availability and quality of healthcare services. Higher scores indicate better access and quality, while lower scores highlight areas needing improvement. Disparities in healthcare access are often linked to economic development, with high-income countries generally having better healthcare infrastructure.
