Alright folks, I need your help: The English-language web seems to have figured out that Taiwan uses cellular location for contact tracing and Singapore uses an app. But what does South Korea use?

In Korea, general public is not using an app to devulge their GPS and cellular location to the health authorities as many overseas might believe. Tracking is only done for small population that are required to quarantine. 3/n

Interesting. So contact tracing for the general population is limited to credit cards, security cameras, and public transport trips? But not phone location? Do you happen to have a link to a Korean/English source for this?

Please refer to Korean govt's official manual on Covid19 response (in English). App use is on page 35 & contact tracing on page 41. See link. 5/nhttps://twitter.com/moohann1/status/1250555506277494784?s=20 …

Ok, so if I understand this correctly: Korea uses manual tracing first and, if that eventually fails, they can use network location on a case by case basispic.twitter.com/t9x5KL2a4K

So to reiterate, location data from the past is used only when needed on an already identified patient to determine their past path of movement. Known contacts that are identified is first tested and if they test positive than their past path of movement is mapped and shared too.
