Undiagnosed conditions pose a significant public health concern for several reasons. Firstly, individuals with undiagnosed conditions may unknowingly transmit infectious diseases to others. Secondly, the absence of diagnosis can lead to severe complications or even death, as early detection is crucial for effective treatment. Lastly, undiagnosed conditions can skew epidemiological data, leading to an inaccurate understanding of disease prevalence and burden, which affects resource allocation and healthcare planning.
