Establishment and promotion of the “Five in One” integrated precise prevention and control system for pollen allergic diseases in northern China

The prevalence of allergic diseases in our country is increasing, and the impact on health is becoming more and more serious. Allergenic pollens are the main source of allergic diseases in northern China. The prevalence of pollen allergy diseases (PiAD) is high in northern China. Anaphylactic shock can be fatal. However, the standardized diagnosis and treatment rate of PiAD is low, specialized doctors and nurses are extremely few, public awareness is seriously insufficient, and misdiagnosis and mistreatment are very common. Therefore, it is urgent to improve the level of prevention and control. The “Five in One” integrated precise prevention and control system includes pollen monitoring, vegetation research, epidemiological investigation, standardized training for medical personnel, and public science popularization and education. Allergenic pollen spreads through the air and is also known as airborne allergen, its concentration in the air is related to the seasons. In spring, allergenic pollen come from trees, while grasses and weeds in summer and autumn. The purpose of pollen monitoring and vegetation investigation is to monitor the seasonal changes in the concentration of allergenic pollen in the air and the corresponding vegetation distribution, providing a decision-making basis to control the allergenic environment from the source for landscaping and grassland ecological administrations. The purpose of the epidemiological investigation is to determine the prevalence of the disease and to study the follow-up strategies. The purpose of medical training is to improve the knowledge, attitude, and behavior (KAB) of medical doctors and nurses working in primary care units in preventing and treating allergic diseases, and to enhance the standardized and systemic diagnosis and treatment level. The purpose of popular science education is to provide the public with knowledge, attitude, and behavior (KAB) on allergic diseases, prevent patients from worsening or relapsing, prevent transiting high-risk populations from developing into patients, and prevent the general population from developing into high-risk populations. Director Wang Xueyan’s initiative of the “Five in One” precision prevention and control system has been widely promoted and applied in northern China for over a decade with good results and huge social benefits. It is in line with China’s new era development concept of putting people at the center and promoting a healthy China and has made significant contributions to the world’s prevention and control of allergic diseases. It has significant practical and far-reaching historical significance.
