OK Did someone mention China? 
No you cannot make any assumptions about 1. What is actually happening in China or 2. whether it would work here, except in very specific instances.
If you want some really good lessons in how to control the virus look at Taiwan who were boarding planes from Wuhan and testing passengers in mid December and swung their pandemic response, a limited lockdown but with effective test trace and quarantine, into action at the end of December and whose figures on Coronavirus cases and deaths (7 in a population of 51m) you can believe. Equally Korea who have succeeded in controlling the virus even whilst battling a centuries old culture of embracing millennial movements now manifested in Christian Evangelical cults churches who insist on their right to mass gatherings. Or Hong Kong opened up again after controlling a third wave, much of it originating in the UK. The Hong Kong man who was reinfected actually first caught it in Hong Kong and then was almost certainly infected on a trip to London. Or even Vietnam. All mounted a response rooted in local public test, trace and quarantine resources.
Kashgar, the main city in mainly Muslim Xinjiang is over 4000kms from mainly Han Wuhan, and is effectively a continuation culturally and ethnically of the other Central Asian (Silk Road) Muslim states. It is however the centre of a new outbreak, though it is highly unlikely that the Chinese are telling the whole story of the epidemiology. Their priority is to portray themselves as confucian rulers in the tradition of the Sage Emperors taking care of their people in the time of pandemic, mainly the Han people who they are flooding into minority areas, nowhere more than Xinjiang where they are trying to eradicate a Muslim Culture in order to assert a Han one. LQ is quite right, if it is in Kashgar, it is highly likely it is spreading in the concentration reeducation camps but Muslim lives do not matter as far as Xi is concerned.
The government portrayed the last outbreak in Qingdao (1000kms in the other direction from Wuhan) as originating with people travelling from overseas. It however is a seaside resort on whose beaches people travelled from all over the country to celebrate the Autumn Moon festival during Golden week in October. Unlikely to be a coincidence.
The webchat coming out of Wuhan's hospitals in November and December was already talking about a new SARs type virus and clearly Taiwan picked up on that and the cases they were identifying enough to mobilise a major response. However Xi was busy with Trump and it wasn't until mid January that anyone dared raise their head above the parapet and suggest they had a huge problem. The Wuhan authorities cleaned up the wet market and hoped to deal with it by suppressing the news, not the virus, delaying an effective response by weeks. Not exactly evidence of effective governance anymore than our shower. Testing millions of people may or may not be a sign of an effective control but it is good PR and a crowd pleaser......
As an aside much is made of Asian culture being conformist and more susceptible to control as a reason why it would not work here. However as much as anything I think the effectiveness of the response in Confucian societies lies in the fact that their Civil Servants have been the esteemed meritocratic elite for centuries, as opposed to an entitled hereditary elite who look down on civil servants, trade and anybody who is not one of them.
