True. In most cases, chronic diseases do not have a single cause. Instead, they are often the result of a combination of factors, which may include genetics, lifestyle choices, environmental exposures, and many other elements. These multiple contributing factors add complexity to the task of identifying significant risk factors and establishing preventive measures. This complexity makes chronic diseases more challenging to prevent and treat compared to infectious diseases, which often have a clear and single causative agent, such as a specific virus or bacterium.
