1. Health promotion includes health education, environmental protection, rational nutrition, drinking safe and hygienic water, improving sanitary facilities, carrying out physical exercise, promoting mental health and developing a good lifestyle.
2. Preventive health care is to take active and effective measures to prevent the occurrence, development and prevalence of various diseases on the basis of studying the objective laws of social population health and diseases and their relationship with internal and external environment and human social activities.
3. Reasonable treatment, early detection of diseases, timely provision of medical services and effective drugs can avoid the development and deterioration of diseases, promote early rehabilitation, and prevent bacteria (worms) from carrying and developing into chronic diseases. Medication is based on the principle of "economy and effectiveness", and the concepts of "more drugs are more effective" and "more is better" are wrong. Medication not only wastes drugs, increases the economic burden of patients, but also increases the possibility of adverse drug reactions.
4. Community Rehabilitation For disabled people who have lost their normal function or have functional defects, comprehensive medical, educational, vocational and social measures are taken to restore their functions as much as possible, so that they can regain their ability to live, study and participate in social activities.
