Zero-COVID, also known as karelm-Zero and "Find, Test, Trace, Isolate, and Support" (FTTIS), is a public health policy that has been implemented by some countries, especially China, during the COVID-19 pandemic. In contrast to the living with COVID-19 strategy, the zero-COVID strategy is one "of control and maximum suppression". It involves 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 is detected. The goal of the strategy is to get the area back to zero new infections and resume normal economic and social activities.
