Found this account from Vietnam on how thw B.1.617 broke through the defences of Vietnam and has already started spreading like a wild fire. The B.1.617 is damm infectious and hits the young very hard. This Vietnam example and other Singapore clusters like Changi and Hospitals shows that once this Variant is inside your border no amount of contact, tracing and testing method will work to contain it. That is why now I believe though the cases are going down in India for a long time there will be a flat line of 1 lakh cases before it tapers down.
The below real world analysis of spread in Vietnam highlights how this virus spreads.

————The second update on May 12, 2021————
Seven B.1.617.2 sequencing results were freshly released yesterday afternoon.
Among them, there are two cases in Bac Ninh and Lang Son:

In other words, the more than 120 local cases in Bac Ninh Province, as well as the large number of hospital feelings at the East British Central Tropical Disease Hospital, may be the source of the Indian experts who entered the country on April 17 with the virus...
Maye, this thing is so JB fierce!
———— First update on May 11, 2021————
Looking at the announcement from the Ministry of Health of Vietnam today, I feel that the poison king ran to Vietnam, which is considered to be a self-investment...
71 new local cases were added, all of which were pre-quarantined as close contacts.
Two of them have been quarantined from May 4 to the present. Nucleic acid tests were negative for three consecutive times, and they were finally positive for the fourth time.
India UK: Meow meow? Is there such an operation?
————The following is the original text————
One,
B.1.617 (commonly known as the "double mutation") is a new generation of poison king, raging in India, this is not news:

But as we all know, you can’t believe a punctuation mark in Indian data...
So we don't know how fierce it is.
two,
Recently, B.1.617 broke up.
The three separated brothers are the second most inconspicuous, and even the ancestral E484Q has been lost, and they are simply ashamed of the name of the "double mutation".
But I never thought that it was this second child B.1.617.2 who played superbly in the United Kingdom (and the world) and quickly obtained the VOC certification of the Public Health Agency of England[1]. He changed and became a follower of B.1.1.7, B.1.1.7, and B.1.1.7. B.1.351 and P.1 are on the same level as the official endorsement of the poisonous king:


However, it is well known that the British are active in sequencing, but they are so bad that they are not fundamentally different from India...
Therefore, we can only experience the mighty power of the new poison king in macro figures, without seeing intuitive cases.
three,
However, now, even intuitive cases have finally emerged.
In Vietnam.
In other words, Vietnam has served as a top student for epidemic prevention for more than a year.
But I often walk by the river, how can I not wet my shoes?
They pulled their hips last month...
First of all, please taste this hotel carefully:




What do you think?
You just can’t believe it. The epidemic prevention department of Yingbai Province, Vietnam, how hard are they doing?
They actually used the hotel above to quarantine the Indians...
I don’t know how to write dead words...
four,
Therefore, thanks to the Ying Pei Provincial Prevention and Control Working Group that has been removed,
It is precisely because of their muffled voices that we have such a rare opportunity to observe the B.1.617.2 massacre at close range (may need to click on the big picture):

lengends:
Blue box-imported cases (departure from India, transit in Dubai)
Red square-Chinese people who have been recruited for no reason and participated in the spread (it should be counted as a local case)
Flesh yellow cubes-local cases
Solid line-identified infection chain
Dotted line-undetermined but possible infection chain
F1-the first generation of close connection
F2——Second-generation close connection
Fives,
Give it a brief dictation.
April 9-23: Five Chinese experts entered Vietnam for business trips through the Friendship Pass, and were transported to the wonderful hotel above in a closed loop for centralized isolation;
April 18: Flight EK394 departing from Dubai arrived at Noi Bai Airport in Vietnam, and some of the Indian passengers were transferred to the same wonderful hotel in a closed loop for centralized isolation;
April 19-27: 4 Indian passengers and 1 hotel staff were tested positive, but the local epidemic prevention department did not consider the possibility of missing the quarantined hotel, and did not promptly trace other people who were quarantined here during the same period. Personnel, such as the protagonist of this story-a group of 5 Chinese experts;
April 23-29: The five-member group of Chinese experts who have been recruited unknowingly travels everywhere in Vietnam...
April 30th-May 4th: The five-member group of Chinese experts finally finished their business trip and returned to China through the Friendship Pass on April 30. They were successively tested positive in Pingxiang (the first time Pingxiang was at a loss Viet Nam was notified...otherwise, both sides will be severely affected this time)
May 2-May 7: Vietnam received a notification and quickly turned around to find out the itinerary of the five-member group of Chinese experts. The first thing that broke out was a karaoke hall in Yongfu Province (the experts came to wash the dust just after the centralized isolation was lifted on April 23, and they really knew how to play...). From May 2 onwards, 7 women who missed the first-generation close-up and 7 second-generation close-up women have been tested positive one after another;
May 3-May 8: The next recruit was a massage room also located in Vinh Phuc province (the experts came to take care of the business on the evening of April 26). Since May 3, 5 women who have missed the first-generation close, 9 second-generation and 4 third-generation women have been tested positive;
May 4-May 7: The VN168 flight from Da Nang to Hanoi on April 29 continues to be identified. From May 4, 4 passengers in the seats next to the experts in the front and rear rows have been tested positive;
May 7th-May 9th: It's not over yet, there are hotels. From April 27th to 29th, the two unlucky guys who stayed with the experts in a hotel in Da Nang were tested positive on May 7th. As of the 9th, there are 8 second-generation close-connected and 1 third-generation close-connected have been tested positive;
May 8th-May 9th: Finally, the local colleagues who are responsible for receiving the experts... From May 8th, 3 first-generation close-ups and 19 second-generation close-ups have been tested positive.
six,
The above is just a real infection path.
In Da Nang, there is a long list of temporarily unsuccessful ones (see the right part of the picture).
Although there is no real hammer, the suspicion is not small.
Because the check-out time coincided with the schedule of the experts' business trip in Da Nang, the place of the accident happened to be a well-known local entertainment venue near the hotel where the experts were staying.
As for the lack of real hammers, it may be because it is not easy for the experts to make real hammers in some entertainment activities outside of work...
Seven,
Everyone must have already tasted the horror of the new Poison King.
The first is the short generation gap.
For example, at the beginning, in the isolation hotel, the poisoned Indian brother only checked in on the 18th. By the evening of the 23rd, the experts were already able to infect women who stumbled in karaoke halls... 10 days later, on May 4, the fourth generation of positives also appeared...
For another example, the experts visited a massage shop in Yongfu Province on the evening of April 26, and the fourth generation emerged after 10 days...
Then it is highly infectious.
Infect three rows before and after flying on a plane, sing a song to infect 7 accompany singing princesses, and press a motorcycle to infect 12 spa girls...
The most frightening thing is the Da Nang infection chain that has not yet been fully hammered... The BN3131 case recruited at the New Oriental Bar in Da Nang had a meeting with 22 beauty salon colleagues in an asymptomatic state. A few days later, 18 of them were recruited. ...
Sure enough, the close observation experience is more terrifying than the dry figures and graphs in Britain or India.
Eight,
Equally scary is Vietnam.
With such a short intergenerational interval and such an erratic chain of infection, they were basically not lost (otherwise this picture would not be drawn...)
Even most of the time, it can be isolated in advance.
Although the situation was thrilling, it barely survived the collapse.
At the time, it was known as a small expert in the anti-epidemic in Southeast Asia. As a result, the real test will come. Cambodia, Myanmar, Thailand, Malaysia and Laos have all crossed, Singapore also has a crisis-ridden appearance... I hope the only remaining seedlings in the Indochina Peninsula can be stabilized~
nine,
MVP is Pingxiang.
Ma yeah, it's a shame...
