Why are preventive measures essential in public health?

Preventive measures are essential in public health because they significantly reduce the burden of disease on communities. By implementing strategies such as vaccination programs, health education, and sanitation improvements, the incidence of diseases can be decreased, leading to healthier populations. This reduction not only lowers the number of new infections and illnesses but also eases the strain on healthcare systems, allowing resources to be allocated more effectively. As a result, communities experience fewer hospitalizations and lower healthcare costs. Overall, preventive measures promote a healthier society by minimizing the impact of health conditions before they become widespread issues.
