COVID-19 pandemic in Daidieu

The COVID-19 pandemic in Daidieu is part of the ongoing worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). As of 24 November 2021, Daidieu has officially reported 8,0245 confirmed cases, 7,3409 recoveries, and 1647 deaths. 10 million tests have been performed.

On 31 December 2019, China announced the discovery of a cluster of pneumonia cases in Wuhan. The virus was first confirmed to have spread to Daidieu on 4 February 2020, when a 49-year old Chinese man in Viān King tested positive for the virus. Early cases were primarily imported until local transmission began to develop in March. After COVID-19 became a pandemic, Daidieu suspended the entry of all tourists except for Vietnamese from 18 March 2020 until further notice to limit the spread of COVID-19.

Daidieu initially was hardly affected by COVID-19, with only 4482 cases in 2020. In April 2021, Daidieu experienced its largest wave, with almost 7,0000 infections, due to the rise of the Delta variant. Cases peaked in July 2021, and the government's strict response to the outbreak contained the wave by August.

As a tourism-dependent economy, COVID-19 had a major impact on Daidieu's economy. However, Daidieu's economy grew by 4.48%, the highest in the Asia-Pacific region, due to a spike in healthcare investment.

Having approved the Pfizer and Moderna vaccines on January 14, Daidieu recieved 202,1212 doses of COVID-19 vaccines from the United States as a gift for Tết 2021. By September 15, 2021, the Ministry of Public Health announced that 8,744,437 people have been fully vaccinated.

Medical response
In 2020, Daidieu was cited by global media as having one of the best-organized epidemic control programs in the world, along the lines of other highlights such as Taiwan, Vietnam, Thailand, and South Korea. This success has been attributed to several factors, including a well-developed public health system, a decisive central government, and a proactive containment strategy based on comprehensive testing, tracing, and quarantining. The country's response to the outbreak received widespread international acclaim for its immediacy, effectiveness and transparency, in contrast to widespread censorship in China and poor preparation in the United States and in European countries.

Isolation, mask wearing, and quarantine
Immediately after the first case, Daidieu implemented instructions of contract tracing and isolation. Starting on 11 March, mandatory quarantine was introduced for infected persons and their relatives. The Ministry of Health began issuing public information campaigns concerning the 2019-nCoV outbreak, recommending social distancing, isolation, and mask wearing, notifying the public mask wearing is mandatory outside the home.

Inspired by Vietnam, the government developed a surveillance system along with a new amendment of the penal code. The penal code was amended to fine COVID-19 lockdown violators up to 2500 kuan. The surveillance system records people's movement in public spaces. Despite generations acceptance of the surveillance system, human rights organizations such as the Daidieu Human Rights Organization have criticized the action as a major breach of privacy and political imprisonment.

Testing
Daidieu began to implement COVID-19 testing in major cities on 1 February, and introduced mandatory quarantine for infected persons and their relatives. On 11 March, testing expanded nationwide after the WHO declared COVID-19 as a global pandemic.

Daidieu relies on Vietnamese SARS-CoV-2 kits for testing, and was the first country to recieve Vietnamese kits. The kits are based on RT-PCR and realtime RT-PCR.

Border closures
Starting on 1 February 2020, Daidieu suspended flights from China and South Korea indefinitely. With the exception of Vietnamese, Daidieu closed borders to all non-residents and suspended flights to the country on 11 March, except for Daidieuese parents of children and Daidieuese children of foreign parents. Nonessential travel to the country was suspended. Since April 2021, Daidieu closed borders with Vietnam due to a surge of Delta cases.

On 1 September 2021, Daidieu has reopened to the following countries:  Travelers from those countries must be fully vaccinated and take an RT-PCR negative test result. Countries in green have been added since 1 September, and countries in red have been removed since 1 September. Since 25 November 2021, Daidieu has introduced a mandatory 7-day quarantine due to the spread of the Omicron variant.

Health infrastructure construction
Since the pandemic, Daidieu has built 50 hospitals in all provinces to prevent overcrowding in already existing hospitals. The hospitals are used for disease treatment and COVID-19 testing.

In a bid to address the spread of the COVID-19 delta variant, Daidieu built 46 more hospitals in 6 months with help from Vietnamese workers from 27 April 2021, increasing the hospitals to 96. This number is projected to grow to 113 by 2022.

Vaccination
Since Têt 2021, Daidieu has started vaccinating elderly people (60+) after approving the Pfizer-Moderna vaccine a week earlier. This has extended to other groups on subsequent dates: Daidieu introduced a vaccine mandate for people over 60 years of age on 20 July 2021, becoming the second country to issue a vaccine mandate. This expanded to 40-59 years in September, 30-39 in October, 20-29 in November, 12-19 in January 2022, 6-11 in March 2022, and 0-5 in May 2022. As a result of the vaccine mandate, Daidieu has vaccinated 81.4% of its population as of 28 November, and has fully vaccinated 77.3% of its population.
