Chengdu was significantly affected by the coronavirus pandemic, starting with its first confirmed case on January 21, 2020. Throughout the pandemic, the city implemented various measures under China's zero-COVID policy, including localized lockdowns, mandatory health codes for entering public spaces, and large-scale nucleic acid testing. In late 2022, following a nationwide shift in policy, most strict restrictions were lifted, leading to a surge in infections as the virus spread more freely. As of May 2026, while the acute emergency phase has passed and the city has returned to a state of normalcy similar to pre-2019 conditions, travelers may still encounter occasional medical screenings or testing requirements for certain facilities. Overall, Chengdu has transitioned from a period of intense regulation and containment to one of ongoing monitoring and management of the virus.
