"The tulips were blooming in Seoul and Dr. Jerome Kim was strolling in his government-issued KF-94 mask with his wife when he got a text message alerting him to a confirmed coronavirus infection in his neighborhood.
...
Kim, who serves as the Director-General of the International Vaccine Institute, clicked on the alert on his phone and it directed him to the municipal site, which detailed the infected individual’s whereabouts over the past several days.
The individual, who was anonymous, had visited a local supermarket on a recent Saturday between 10 a.m. and 10:15 a.m. to buy chilies, which was confirmed with CCTV footage and credit card transaction data, Kim recalled.
...
That alert was one of dozens, if not hundreds, that millions of South Koreans have received since the coronavirus arrived in the country on Jan. 20, Kim said. He added that such sharing of information, despite its data privacy implications, has helped to keep the infection rate down even as businesses reopen."
Ugh....I wouldn't like living in that kind of 'transparency.' So everyone that tests positive, their personal business is mass texted to everyone, down to what they bought in the store and when?
Is that really necessary?
