What does the epidemic inflection point mean?

The inflection point of epidemic situation is an important time node. The emergence of inflection point can bring new changes to health policy formulation, disease control scheme, control mode and people's daily life, which is closely related to society.

The epidemic inflection point is based on the existing control measures, virus incubation period, outbreak period and other information. After the inflection point, the case curve should continue to rise but the growth rate will slow down, and then it will start to decrease after reaching the highest point.

The inflection point of the epidemic is not fixed, but changes with the existing changes. Early detection of infected people, early isolation, strengthening contact tracking, isolation and other measures can promote the emergence of inflection points as soon as possible.
