1. On 13 January, Shanghai announced the designation as a medium-risk area of a milk tea shop located at 228 Silent Park Road in the Quiet Zone, the source of the transmission chain, who had returned home from abroad for 14 days, had been separated from his family on the last day of the seven days and had tested positive and had caused infection among persons in close contact during his activities. 2. The risk zone is 20 square metres, not too big in Shanghai, but precisely and in a timely fashion. When there is an outbreak in Shanghai, people outside Shanghai will feel that the whole of Shanghai is a risk zone, but those living in Shanghai will feel that only the serenity zone is a risk area. 3. As at 13 January, 25.5 per cent of the country's imported cases were outside Shanghai, while Shanghai faced greater pressure from internal imports owing to the high number of mobile populations. However, its anti-epidemic model is probably the best model for a lasting battle against the epidemic, because the lives of Shanghai’s people are largely unaffected. At the same time, if there are no other cases in Shanghai after this closure, the pre-spring trip code can be removed. In Shanghai, two cases of confirmed and three cases of unsymptomatic infections were detected, and the source of the transmission chain was the “14+7” quarantine. Why is it that only 20 square metres of milk tea shops are designated as medium-risk areas?
On 21 December last year, the high-risk areas in Shanghai were cleared, all adjusted to low-risk areas. 23 days later, on 13 January, Shanghai announced the designation of a 20-square tea shop as a medium-risk area.
The tea shop became instantaneous red and became the country's highest-profile tea shop.
This area, known as China’s smallest epidemic risk zone, is only 20 square metres. The coordinates are located in the Shanghai Peace Zone, with the name number 228 and the name of Silent Garden Road.
The quiet zone is located in the centre of Shanghai, with a small area, a high population density, and six districts adjacent to it. This tea and milk shop, 228 Silent Park Road, is just 210 metres from the entrance to station 1 of the subway line 2/7. It is conceivable that there should be a larger flow of people in the tea shop.
Why would a tea shop be classified as a medium-risk area?
The day before, information was posted on the Internet that there had been an outbreak in the Quiet Zone, where the Director of the National Centre for Infectious Diseases Medicine and the Director of the Infection Unit of the University of Wangshan Hospital, a subsidiary of the University of Khatami, were isolated from their homes.
In response, the authorities replied that the screening process was normal. Zhang Wenhong also stated publicly that he was not segregated from his home, and that the Internet was a “mongering”!
For more than two years now, the residents of Shanghai have become accustomed to this: hospitals and districts are often shut down, nucleic acids are brought under control, and when the news circulates online, the results of the nucleic acid come out, and if there is no problem, the district and the hospital are unsealed.
This time, however, the scene turned one day later: the serenity zone did show up in a medium-risk area. The source of the transmission chain is a person who has returned from abroad, and has completed 14 days of isolation, with a positive test on the last day of the seven days of family isolation.
It is true that no other positive persons were found in the neighbourhoods in which the infected person lives, but during his or her activities, he or she causes an infection in close contact.
Of the five persons diagnosed as positive, two were diagnosed and one was an unsymptomatic infected person, all of whom were staff members of the disease-related tea shop, with the remaining one being a sister living with one of the staff members.
It was reported that, as at 1900 hours on 13 January, 304 persons in close contact with the above-mentioned five persons had been screened in Shanghai and quarantine controls were in place, with negative results from the Covid-19 virus nucleic acid test. The result of the screening was that Shanghai only classified the tea shop in the quiet area as a medium-risk area.
This tea shop, the smallest “medium-risk area” since the outbreak, has been seen by many as a microcosm of the precision of the epidemic in Shanghai. The old customers of this tea shop, as well as the Internet, have been encouraged in the comment area since the announcement, “May you cheer in Shanghai! When you heal, let's celebrate with grass!”
The experience of vaccination in Shanghai has been summarized by the enthusiasts themselves, such as the lack of full-scale nucleic acid testing, the absence of seals, and the absence of major medical accidents caused by the epidemic.
Thank you for the tea shop.
Is it too loose, or is it precisely controlled? Can the Shanghai model be replicated?
The size of a medium-risk area was so small that it was unexpected for many people.
If there is an outbreak in Shanghai, people outside Shanghai may feel that the whole of Shanghai is a risk zone. Why else would Shanghai's trip code have an asterisk?
But those who live in Shanghai will feel that only the quiet zone is a risk zone, and they will be safe outside the quiet zone. But those in the quiet zone will say that only this tea shop is a risk zone, and the guilin powder next door will be open as usual.
Why do you feel like this? In China, there are occasional cases only in local areas, and the risk of contracting the Covid-19 virus as a whole is very low.
In some cities, as long as one case is detected, the entire city may have been examined for nucleic acid, but in Shanghai, no full city test has been conducted since the Covid-19 outbreak.
In some cities, if a similar situation occurs, at least a few streets will be closed if the city is not sealed. In Shanghai, when the epidemic broke out last November, the infected people also lived in small areas. But this time, it was just a 20-metre shop.
On 3 August 2021, Shanghai announced the inclusion of the 1,500-carried Xijiang district of the new town of Huaxia II in the province of Chuan, Pudong, as a medium-risk area, with all the other regions of Shanghai being low-risk.
The risk area is exactly 20 square meters. Is it Shanghai's too big, too loose, or is it precisely controlled?
Many people ask the question: Is it not possible for this infected person, who is in isolation from home to a tea shop, to pass through the rest of the world? The tea shop workers are infected, not in closed loops, they can also move in Shanghai and they can contact other people.
What about the promised time and space?
The “carriage” of the various necessities of life has become the busiest sight on the ground, with nearly 5,000 residents in the heart circle listed as the first day of closed management of the medium-risk areas. According to some of them, Shanghai has set a precedent for the designation of a small area as a medium-risk area, as well as a safety model for medical treatment, food, take-out and trans-shipment after the closed zone. These questions are understandable. The epidemic has been spreading for more than two years, and in many cases it has been felt that the virus is inexorable, and sometimes it has to be “opportunityful for 3,000 people” in order to defend itself. It seems that zero is the norm. In particular, it is the world that believes or does not believe that the Covid-19 virus has taken root on this planet.
Shanghai, China’s most populous city, and one with the largest number of entrants, has accumulated a wealth of experience with the disease for more than two years. Shanghai has also seen three medium-risk zones in November, but the source of the infection is not direct entry from abroad, but rather from other provinces and cities in the country. So we can believe that Shanghai operations are precisely controlled. Of course, in the face of a powerful virus, no one can be 100% certain.
Is Shanghai able to withstand the stress of the epidemic when 197 cases are imported abroad for seven days and 3045 cases are imported throughout the year?
In the case of persons entering the country abroad, the “14+7” isolation measure is applied in Shanghai, i.e., 14 days of concentrated isolation and 7 days of family isolation. In the interior, this is the shortest period of isolation. In contrast, some places have been isolated for as long as 21+35!
Although the isolation period is the shortest, there has not been a major outbreak in Shanghai before, which explains the fact that the “14+7” isolation is sufficient if it is done well. Fourteen days would have been enough if the virus had not been too contagious. Without a scientific look at isolation, but blindly pursuing it, it might not have been enough for a month. Shanghai, however, is under severe pressure. According to data published by the National Health Board and the Shanghai Health Commission, as of 13 January, China had a cumulative total of 1149 cases imported from abroad, of which 3045, or 25.5%, were imported from Shanghai.
The largest number of flights took place during the outbreak at Shanghai Pundong International Airport, from 7 to 13 January, with 197 cases imported from Shanghai during the past week, which also led to the collapse of nearly 30 foreign flights.
With the global outbreak of the Omicron tsunami, more and more cases were imported into China. From 7 to 13 January, 197 cases were imported from Shanghai during the past week, more than the current local outbreak in Tianjin.
In addition to external import pressures, because of the large number of mobile populations, Shanghai has had to face internal import pressures. Three outbreaks occurred in November and December last year, resulting in four medium-risk areas in Shanghai, directly attributable to those infected from the provinces and cities.
In the face of the stress of the epidemic, Shanghai is not a big deal, and it can even be said to be “on a thin ice line.” Shanghai is also adapting its response to the epidemic, but with a view to making it more effective and accurate in order to avoid, as far as possible, the unnecessary impact of the response on people's lives.
For example, as a result of the precedent of contaminated international flights and the resulting infection of passengers, Shanghai has increased the amount of clean time available for international flights.
For example, in the aftermath of the epidemic, Shanghai also expressed the need to strengthen the management of household isolation to reduce the risk of the epidemic.
Shanghai, although sporadic, should be the best city in China to fight the epidemic, because the lives of its people are largely unaffected. If neither Shanghai can withstand the pressure of the epidemic, China may not be able to withstand it.
The anti-epidemic model of Shanghai is perhaps the best model for a lasting fight against the disease.
In the face of the epidemic, many things are uncertain, but one thing is certain: this medium-risk area of 20 square metres, now that it has been blocked, no one will go in and out, no new cases will naturally occur within 14 days, and then it will be properly unsealed.
If there are no other cases after Shanghai, the pre-spring trip code will be able to pick stars!
May peace be upon Shanghai.
