Epidemiology is a discipline integrating
methodology and applied
science, whose mission is to prevent and control
diseases and promote
health. This
review introduces the new progress of
epidemiology from five aspects
communicable diseases,
chronic diseases, systems
epidemiology, implementation
research and
big data of
health care. New
projects and constantly emerging
technologies in the field of
infectious diseases are inspiring, while more
attention should be paid to the environmental factors of pathogen variation. In the field of
chronic diseases, there is an urgent need to study the
multimorbidity of the
elderly. The
role of infectious inducers and
human microbiota in the occurrence and development of
chronic diseases has been gradually revealed. Systems
epidemiology, which is of great significance to achieve precision prevention is a new branch and an important supplement of modern
epidemiology. Implementation
research, is a
bridge connecting basic scientific
research and
public health practice and
will provide evidence to support the effective implementation of the
Health China Action Plan. The development of
health care big data is based on
digital public health, which provides a broad
research platform and abundant data
resources for
epidemiology, and
will promote the fundamental transformation of the service and management mode of
public health.
