Public health has long been a cornerstone of societal well-being, evolving from simple sanitation measures to complex healthcare systems that span nations. However, the 21st century has introduced unprecedented challenges. Pandemics, aging populations, rising healthcare costs, and the increasing burden of chronic diseases have put immense pressure on healthcare infrastructures worldwide. Traditional public health approaches, reliant on historical data and manual intervention, often struggle to keep up with the rapid spread of diseases, unpredictable outbreaks, and the logistical challenges of delivering care efficiently.
