Zero-COVID, also known as COVID-Zero and "Find, Test, Trace, Isolate, and Support" (FTTIS), was a public health policy implemented by some countries, especially China, during the COVID-19 pandemic. In contrast to the living with COVID-19 strategy, the zero-COVID strategy was one "of control and maximum suppression." It involved using public health measures such as contact tracing, mass testing, border quarantine, lockdowns, and mitigation software in order to stop community transmission of COVID-19 as soon as it was detected. The goal of the strategy was to get the area back to zero new infections and resume normal economic and social activities.
