These people include the elderly, children, pregnant women and patients with chronic diseases. The elderly are prone to various diseases due to the decline of physical function and weakened immunity, so special attention and care should be paid. Children and pregnant women are vulnerable groups in society, and their health and safety should receive special attention and protection. Patients with chronic diseases include patients with chronic diseases such as hypertension, diabetes and heart disease. They should get long-term management and treatment to keep healthy. For the key management groups in these jurisdictions, the community and relevant departments will take a series of measures, such as regular physical examination, health education and disease management, to ensure their health and well-being. Such management measures are helpful to improve the overall health level of residents in the jurisdiction and promote the harmonious development of the community.
