Prevention models

Prevention models are frameworks used to reduce the risk or occurrence of health problems, social issues, or failures before they happen. They focus on identifying risk factors and implementing strategies to stop problems early. For example, vaccination programs prevent disease outbreaks, while safety regulations reduce accidents. Prevention can be primary (stopping issues before they start), secondary (early detection and intervention), or tertiary (minimizing impact after a problem occurs). These models help allocate resources effectively and promote healthier, safer communities by addressing issues proactively rather than reacting after problems emerge.
