Leading Chinese Dr. Zhang Wenhong (perhaps now second only to Dr. Zhong Nnashan in fame) telling Bangladesh on camera:
"Home isolations FAILED in Wuhan."
It is a costly, technical and non-political lesson all other countries, not only Bangladesh, should learn from
A THREAD
Dr. Zhang said in the video: We found out in Wuhan that the reason why there were so many patients in Wuhan was that we (first) enabled home isolations, which we (later) realized was a failure.
Dr. Zhang said: Since I haven't been to Bangladesh, I don't know how big a (usual) family's house/apartment is in Bangladesh. In China, we have many people living inside each house/apartment, and the (average) place is small, so home isolations failed in the end.
In Chinese Dr. Zhang's original words 我们在武汉发现,武汉的病人为什么这么多,是因为我们在居家隔离,我们认为是失败的。因为我没有去过孟加拉,我不知道孟加拉的家庭的房子是有多大,因为在中国,我们每一家房子里面住的人都比较多,地方比较小,所以所有的居家隔离到最后都失败了。

A @HarvardBiostats professor's March 7 tweet on her co-authored paper (published on April 10 on @JAMA_current https://jamanetwork.com/journals/jama/fullarticle/2764658) showing centralized quarantine squashed coronavirus https://twitter.com/XihongLin/status/1236274898760327168

basically, over a month has passed, nothing happened.
Because
it "is a cruel overreaction and a violation of human rights" and “We couldn’t under any circumstance do what China did,”
BUT centralized quarantine in Wuhan was on average more or less 2 weeks, People get out if they test negative outside 24 hours. All facilities have closed. ZERO death, of over 12k people, was reported in them. Internet connection, video chat, all enabled. What's to be afraid of?
The only thing we learn from history is that we learn nothing from history. Even such recent history.

Of course I hope with all my heart that with or without centralized quarantine things could work out well rapidly in US, Europe, everywhere.
The dire fact on the ground remains 1) no centralized quarantine, allowing coronavirus to pass between dearest family members and then the immediate community 2) no institutional/mass-scale contact tracing
