A public health team in Delhi conducted a cross-sectional survey in January 2024 to assess the burden of type 2 diabetes mellitus in a population of 50,000 adults aged 30–60 years. They identified 2,500 individuals with diabetes (both newly diagnosed and previously known cases). In the same population, during the 12-month period from January to December 2023, 300 new cases of diabetes were diagnosed. What is the prevalence of diabetes in this population, and which measure best reflects the disease burden at a single point in time?
