A holistic approach is crucial because diseases and health conditions are rarely caused by a single factor. For instance, the onset of cardiovascular disease can be influenced by genetic predisposition, lifestyle choices, socioeconomic status, and environmental exposures. Traditional epidemiological methods might overlook these intricate interdependencies, potentially leading to incomplete or ineffective public health interventions. By adopting a holistic perspective, epidemiologists can develop more effective, targeted, and sustainable interventions.
