Medical sub-centers also play an important role in disease prevention, public health and health education. They can help residents prevent and control the spread of diseases through regular physical examination and vaccination. In addition, medical sub-centers can also carry out some health education activities, such as health lectures and nutrition guidance, to improve residents' health literacy.
However, there are still some problems in the construction of medical sub-centers at present. Due to limited conditions, some medical sub-centers lack professional doctors and high-quality medical equipment, which is difficult to meet the health needs of residents. Therefore, we need to take effective measures to increase investment in medical sub-centers, build a high-quality service network, and provide more comprehensive and convenient medical services. Only in this way can we truly improve the primary health care system and protect the health rights and interests of residents.
