Lockdown On February 28, 2022, introduction of travel restrictions was announced by the Shanghai Municipal People's Government and negative PCR testing within 48 hours of the travel became mandatory. In addition to the negative PCR testing, travel from "control area" to "prevention area" was conditioned by the 14 days mandatory quarantine at its own residence (quarantine in commercial facilities such as hotel does not qualify) within the "prevention area". On March 15, Civil Aviation Administration of China announced that the international flights into Shanghai shall be diverted to other cities. Shanghai decided to adopt "area-separated and batch-separated control" (Chinese: 分区分批防控) starting on March 28. On March 27, many markets got crowded, with some scholars arguing these conditions were due to city closure. This was extended on April 1. Some media suspected that cases were underreported. Wang Keyu, a staff member at
Huashan Hospital stated that (locally-available) COVID-19 vaccines offered weak protection against the
Omicron variant, and that a wide range of COVID-19 testing control was important and necessary. By March 29, over 9.1 million people had been tested by roughly 17,000 testers in roughly 6,300 testing areas. By April 1, over 18 million people had been tested. Since April 1, most areas of Shanghai are under three-level control. The levels includes "closed area" (), "control area" (), and "prevention area" () and typically spans the size of a residential complex, later (in June) granulizing into individual buildings. On April 5, the lockdown was expanded to encompass the entire city, affecting the population of 25 million. On April 11, Shanghai published the list of closed areas, control areas, and prevention areas. On April 11, Shanghai officially announced all areas are under three-level control and clarified. Closed area contains people who tested positive for COVID-19 in the neighborhood, the "7-7" quarantine policy is required to follow, during 7-day closing period, if there was no people who tested positive, the restriction will be the same as the restrictions of a "control area". People in control areas can, with limit, collect essential supplies within the neighborhood. Neighborhoods which are listed as prevention areas have no reported case within 14 days. People in prevention areas should only travel within the street. On May 6, multiple areas (including "prevention areas") was put into a so-called "silent period" (), banning all entry and exit, including delivery shipment. The stated rationale was that some positive cases appeared in prevention areas, and for a "final assault" () on the case count. On May 17, another wave of "silencing" started, this time spanning the entirety of multiple districts, again under the name of a "final assault". On May 6, In Shanghai, which is entering its second month of lockdown, city officials said cases have been declining since Apr 22 and its outbreak is under control. From May 29, plans were announced to ease the lockdown on June 1. The adjustment entails: • People entering public areas and taking public transport must now show a negative
PCR test result taken with 72 hours. The original requirement was 48 hours. The standard for leaving the city remains unchanged: negative PCR test taken within 48 hours must be shown along with a negative antigen test within 24 hours. • A ban on
residents' committees adding additional restrictions in all areas except those marked "closed", "control", "mid-risk", and "high-risk". This has attracted criticism from these committees, who claimed that their extra restrictions were not their own decisions, but unwritten telephone orders from above. • Lockdown measures on businesses are to be lifted as an effort to help the economy that has been hit hard with strict restrictions. The adjustments were made to "promote epidemic prevention and control as well as economic and social development, and resume work and a return to normal life," the city official added in the May 29 press conference. Shanghai declared that it would do its best to recover the losses caused by the epidemic. On June 3, four neighborhoods in Jing'an and Pudong were put back into "closed" lockdown and designated as "mid-risk" due to seven new cases found the prior day. On June 7, some more areas are restricted to "closed" area. In early July, many cases reported is related to a person who visited illegally operated KTV.
Mass testing and Isolation On March 4, Shanghai instituted a policy of mass
COVID testing. In every building with a positive COVID-19 case, all residents were required to undertake individual "nucleic acid" COVID tests. Other areas undertook
pooled COVID-19 testing. Shanghai residents were required to undertake nucleic acid tests throughout the lockdown, ranging from multiple times per week to once per day. Tests were initially posted on the Health Cloud APP, but over the course of the lockdown migrated to mini programs on Alipay or WeChat. Tests were required for all regions regardless of risk, and would generate a colored
health code (). Each district was responsible for implementing their own system around the code Green codes were issued to people with negative antigen tests, yellow for close contacts of positive cases or those who did not test, and red for positive cases. Enforcement of health codes was left up to individual districts and communities; some locations forbade residents from leaving their neighborhoods regardless of the health code. Residents that refused COVID testing would see their health code turned red. Some neighborhoods threatened permanent red-code status for those who refused or resisted transportation to a quarantine center, with one location promising on April 12 that such people would "never be rehabilitated" (永不摘帽). Shanghai authorities converted schools, residential buildings and other structures into quarantine facilities when designated facilities ran short on space.
Education As the caseload in the outbreak was growing, there were messages like "Shanghai will stop school" on
Weibo. On March 8, a Shanghai official denied the possibility, but for students absent due to COVID-19 the platform "Air Class" would allow for education to continue. On March 12, in-person school was suspended, with students able to participate using platforms such as "Shanghai V-Class" or "Shanghai Education" instead. On May 7, Official announced the
National College Entrance Examination in Shanghai will be extended to June,
Senior High School Entrance Examination in Shanghai will extend to July, with lab and English speaking test section being removed and counted as full credit toward final score. Shanghai Ministry of Education stated all middle and high school student could come to school before June 14.
Transportation On April 13, the
Public Security Bureau of Shanghai announced that people in prevention areas must not enter "closing areas"; nonessential automobiles would also be prohibited.
Law enforcement On March 22, two people posted information on a group chat saying Shanghai was about to perform a "city closure"(feng1cheng2 封城). The next day, the
public security bureau of Shanghai investigated both for the crime of posting false information intentionally. On March 26,
Wu Fan, the vice-principal of
Shanghai Medical College stated that Shanghai would not go into lockdown because of how much the city contributed to the economy of China. In general, mainland China has strict laws controlling crime related to pandemic management. According to Chinese jurist
Luo Xiang's
Criminal Law Textbook, people who don't obey basic isolation rules when they know they have tested positive for COVID-19 have committed the crime of harming public safety (Chinese: 以危险方法危害公共安全罪). Other people who don't obey isolation rules but caused heavy losses may get accused of the crime of distraction of disease prevention (Chinese: 妨碍传染病防治罪). People who post allegedly false content about COVID-19 control policies may be accused of the crime of posting false information (Chinese: 编造、故意传播虚假信息罪). On April 18, the Public Security Bureau of Shanghai posted that the message "The women who gave preterm birth failed to ask for help and died because of hemorrhage" was false information. The women gave natural birth and were sent to a hospital on time and successfully gave birth. The publisher Zhang had been captured. There have been cases of fraud and illegal marketing during the Shanghai lockdown. On April 16, the legal representative of a medical company was arrested for selling 29,000 masks that did not meet health standards. On April 19, a man was arrested for selling rotten pork for over 320,000 yuan. == Impacts ==
