Which country recorded the highest global prevalence of childhood diabetes cases and fatalities in 2019?

To answer this question, we would need to conduct a multi-step research process:

1. Identify Reliable Sources: The first step would be to identify reliable sources of information. This could include databases from the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), or other reputable health or medical research institutions.

2. Search for Relevant Data: The next step would be to search these databases for data on the global prevalence of childhood diabetes cases and fatalities in 2019. This could involve using search terms like "childhood diabetes prevalence 2019" or "childhood diabetes fatalities 2019."

3. Analyze the Data: Once the relevant data has been found, the next step would be to analyze it. This could involve comparing the prevalence and fatality rates of childhood diabetes in different countries to identify which had the highest.

4. Draw Conclusions: Based on the analysis, we would then be able to draw conclusions about which country had the highest global prevalence of childhood diabetes cases and fatalities in 2019.

Please note that as an AI, I don't have real-time access to databases or the ability to conduct this research. You would need to follow these steps yourself or consult with a health professional or researcher who can.
