That's simply freaking amazing with regards to the speed of testing and how the gov't reacts when it comes to test almost all the population of the city. If am not mistaken the population size of Shenzhen is millions more than Toronto and yet we here can't be bothered to get tested or be tested because the government in it's collective wisdom was and is unable to procure, made all the necessary PCR kits available to all of it's supposed population of 14.6 million people for the province (Toronto pop. 6.8 million)I'm in Shenzhen. We had 2 cases yesterday. I believe the whole city was tested after that. I got tested last night around 10:30. There were a few hundred people there with 8 test stations. We were pooled into groups of 10. The lines moved quickly. The whole process took 10 mins after I got there. This afternoon my health code was updated to show a negative result within the past 48 hours. It was a painless process. Everyone was very cooperative. I don't think there is any new case today, but I'm expecting they may pop up from the tests done yesterday. If so, we may have to be tested in another couple of days. They did do contact tracing on the original 2 cases and found around 100 close and secondary contacts and probably isolated them.
There is no lockdown. But some apartment complexes require showing a negative test result within the past 48 hours on the health code to enter.
We're advised to count 5 days from the outset of our symptoms as a form of quarantine and observe our conditions. If it worsens stay home if then 5 days from your initial symptoms your condition improves you're good to go i.e. go back to work. No testing necessary to confirm if you're free of Covid-19. It's crazy but at least we have FREEDOM AND OUR GOVERNMENT KNOWS HOW TO SAY SORRY.
