This book deals with all related issues regarding hospital and public health safety in modern times.Preventive healthcare (alternately preventive medicine, preventative healthcare/medicine, orprophylaxis) consists of measures taken for disease prevention, as opposed to disease treatment. Just ashealth comprises a variety of physical and mental states, so do disease and disability, which are affectedby environmental factors, genetic predisposition, disease agents, and lifestyle choices. Health, disease,and disability are dynamic processes which begin before individuals realize they are affected. Diseaseprevention relies on anticipatory actions that can be categorized as primal, primary, secondary, andtertiary prevention. Public health aims to improve the quality of life through prevention and treatmentof disease, including mental health. This is done through the surveillance of cases and health indicators,and through the promotion of healthy behaviors. Common public health initiatives include promotinghandwashing and breastfeeding, delivery of vaccinations, suicide prevention and distribution ofcondoms to control the spread of sexually transmitted diseases.The book is expected to create the needin Public Health to be established in the public sector.
