28 cases of infection in two days, why is Beijing like a big enemy?

In the past two days, a total of 28 positive infections have been reported in this round of Beijing epidemic

At 10:30 p.

Although a press conference was held in the afternoon, the Beijing Municipal Government Information Office held an additional press conference that night, at which 4 new confirmed cases in Beijing, 1 case of nucleic acid review positive person, and initial nucleic acid test were reported.

A citizen who lives in Songyuli told Badian Jianwen that shortly after the press conference, his community was put under emergency control

On the second day, the latest confirmed news came one after another.

The trajectory of the epidemic involves 6 urban areas including Dongcheng and Chaoyang

From the very beginning of this round of epidemic in Beijing, three independent chains of transmission have emerged—decorators, tour groups for the elderly, and schools

At present, the source of these three transmission chains is unclear, and the first confirmed person in the chain is not a high-risk group for epidemic prevention and control

Beijing, a mega-city, has been seeing sporadic confirmed cases in recent times, but in the end, it was possible to quickly find related cases and quickly contain the epidemic

At a press conference on the afternoon of April 23, Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, introduced: "The preliminary epidemiological results show that it has been hidden for a week now

The Omicron variant spreads extremely fast, and the transmission days between generations can be as short as 2-3 days.

Eight points Jianwen noticed that 20 of the infected people lived in three districts, of which 15 were diagnosed in Chaoyang District, in addition to Shunyi District and Fangshan District

An infectious disease expert told 8:00 Jianwen that, judging from the current situation, the virus is likely to have spread at a low intensity in the city for a long time, and the transmission time may even have exceeded a week

There is only one elderly couple among the infected persons related to the transmission chain of the elderly tour group

Another 10 infected people are students of Huiwen Middle School Weeping Willow Branch, and 9 of them were diagnosed on April 23, and they were still in normal school the day before

In addition, three family members of a student were also infected.

The above-mentioned epidemiologist told 8:00 Jianwen that the discovery of so many confirmed cases in the school also indicates that a certain scale of community transmission has occurred

What worries virologist Chang Rongshan the most is the four decoration practitioners among the infected people
.
He believes that "the turnover of decoration workers is very large, and they rarely interact with people in other industries.
If everyone in this situation can be infected, it means that the epidemic situation in the community is surging, and the scale is not small
.
"

In addition, it is also worrying that one of the 20 infected people is a takeaway courier, who was found as a group who should be checked out
.
Delivery workers are highly mobile occupations and have a higher risk of transmission after infection
.
In June 2020, a deliveryman in Beijing was diagnosed with the disease, and his average daily order volume can reach about 50 orders
.

On April 23, Pang Xinghuo pointed out at a press conference on epidemic prevention and control that the infected people are diverse and have a wide range of activities, which have now involved schools, tour groups and many families
.
With the intensification of investigations, additional cases will be found in the future
.

Can Beijing withstand the test this time?

3 districts, 5 or more occupational scenes with little overlap, this is the most severe situation Beijing has faced since the new virus strain with R0 exceeding 10 landed in China
.

Beginning in Tianjin, this new strain directly triggered a nationwide escalation and control war.
The control measures are being upgraded, and the spread of the virus is also accelerating
.
In China's four major cities, which are considered super cities, the virus has reached Shenzhen, Guangzhou and Shanghai and impressed local residents, and finally, this time, it has also come to Beijing
.

Where did this epidemic come from?

"Beijing has no international flights.
In February, the Winter Olympics were almost safely passed, and it looks very safe
.
However, in its surrounding Hebei, after the New Year, the intermittent sporadic cases have hardly stopped," Chang Rongshan believes.
The virus that appeared mysteriously this time may only reveal a corner of the virus that has been hidden and spread in the suburbs of Beijing
.

Where will this mysterious Beijing epidemic go?

"If the prevention and control measures are appropriate and not expanded, "there should be two or three hundred people who may not be able to escape.
"
Chang Rongshan told Eight Point Jianwen: Of course, the premise depends on the prevention and control in the next few days.
Situation - It depends on whether the response speed can quickly find all positive infected persons and fish them out
.

"Before Omikron, you need to look at the situation in the first week, but after Omikron, you don't need to wait for a week.
You can roughly know the overall trend by looking at the infection situation in three or five days
.
" The virologist analyzed
.

However, even if this epidemic can be quickly subsided, what will happen next?

As a mega city characterized by dense population and intensive human activities, it is almost a breeding ground for a virus that is easy to spread and hides.
It has almost become the norm
.

For this kind of super virus that requires extreme epidemic prevention measures after almost one case is detected, detection, sealing and control, nucleic acid, clearing, re-detecting, and then sealing and control have almost become the norm for dealing with this new strain
.
In Shenzhen, which encountered the epidemic at almost the same time as Shanghai, it was cleared on April 6, and a new confirmed case was found on the 8th
.
In Dongxing, a small border town in Guangxi, because of the intermittent outbreaks, the lockdown has been in place for 51 days since mid-February
