[Ed. – Not persuasive. The contacts of people who do turn up with symptoms can be traced quickly. Otherwise, the point is not that tracing would prevent new outbreaks; it’s that tracing would be a basis for central authorities wielding coercive power over the people based on predictive models, not on demonstrated events. That cannot be the “new normal.” Note that tracing beyond what is already available would not have reliably prevented any of the “infection spike” examples listed. It would, however, be used to justify demanding more and more surrender of privacy in the service of a scheme to “manage the population” based on models.]
A top world health official Monday warned that countries are essentially driving blind in reopening their economies without setting up strong contact tracing to beat back flare-ups of the coronavirus.
The warning came as France and Belgium emerged from lockdowns, the Netherlands sent children back to school, and many U.S. states pressed ahead by lifting business restrictions. …
Authorities have cautioned that the scourge could come back with a vengeance without widespread testing and tracing of infected people’s contacts with others.
Fears of infection spikes in countries that have loosened up came true in recent days in Germany, where new clusters were linked to three slaughterhouses; in Wuhan, the Chinese city where the crisis started; and in South Korea, where a single nightclub customer was linked to 85 new cases.
