Epidemiological shift of hepatitis A in EAGLE countries - a projection

Area of Science:

• Epidemiology
• Public Health
• Health Economics

Background:

• Rapid economic development and improved sanitation in many regions are altering the epidemiology of infectious diseases like hepatitis A.
• An epidemiological shift means children are less exposed early in life, leading to potential infection at older ages when the disease is more severe and costly.

Purpose of the Study:

• To examine the potential consequences of the ongoing epidemiological shift of hepatitis A in developing regions.
• To model the future public health and economic burden of hepatitis A in a hypothetical rapidly developing country.

Main Methods:

• Regression analysis was used to correlate annual hepatitis A mortality with the Human Development Index (HDI) across Emerging and Growth-Leading Economy (EAGLE) countries.
• Data from EAGLE countries (1995-2010) were weighted by population to create a model for a hypothetical emerging market country.
• Separate regression models assessed hepatitis A mortality trends in relation to HDI and time.

Main Results:

• A significant inverse relationship was found between HDI and hepatitis A mortality; each one-unit increase in HDI corresponded to a 2.3016 deaths per 100,000 decrease in mortality.
• The hypothetical country's HDI was projected to increase by 0.0073 annually, with hepatitis A mortality decreasing by 0.0168 per 100,000 people each year.
• Hepatitis A mortality in the model country is predicted to reach 0.11299 deaths per 100,000 by 2030, with its HDI nearing developed country status by 2025.

Conclusions:

• The developed model, based on EAGLE country data, illustrates the health and economic shifts associated with rapid development in emerging economies.
• Understanding these hepatitis A trends is crucial for informing public health policies and ensuring regular updates to mitigate future disease burden.
• The study highlights the dynamic interplay between economic development, public health interventions, and infectious disease patterns.
