In a country under the rule of law, health should be positioned as the object of the state protection obligation, which not only highlights the state task of protecting citizens" health, but also guides the public power to perform its duty of protecting citizens" health rationally. With the advent of risk and the change of health factors in modern society, the country needs to implement comprehensive prevention if it wants to fully protect the health of citizens. As a result, the level of health protection has improved, but individual rights have been more restricted, and the relationship between health and freedom has become increasingly strained. Under the background of building a healthy country, the administrative organs must break through the boundaries of the original police power, but they must not give up the basic requirements of administrative rule of law. The state should emphasize the subjectivity of individuals and respect that citizens are the first responsible person for their own health, on this basis, the justification of intervention measures should be justified.
