11/11—Self-quarantine violations in South Korea: 1.6 per 10,000

Self-quarantine non-compliance during the COVID-19 pandemic in South Korea
The median number of individuals quarantined per day was 36,561 (interquartile range of 34,408-41,961). The median rate of self-quarantine violations was 1.6 per 10,000 self-quarantined individuals (range 0.0-8.0 per 10,000 self-quarantined individuals). The additional sanction [a one-strike out policy] has no significant impact on the number of violations among quarantine individuals (p=0.99).

The number of individuals quarantining and individuals who have violated quarantine in South Korea between March 22 and June 10, 2020. The vertical dashed line in red indicates the implementation of a one-strike out policy and an increased penalty for the violation of individuals from self-quarantine. A) The daily number of quarantined individuals as determined by contact tracing of locals and international travelers. B) The daily number of violators. C) The daily non-compliance rate of those in self-quarantine.

Coronavirus Disease-19: Quarantine Framework for Travelers Entering Korea
South Korea is operating a flexible quarantine management system which is based on the results of epidemiological investigations of patients arriving from overseas with COVID-19. South Korea has designated countries with a localized, high prevalence of infection as “quarantine inspection required areas.”

Aggressively find, test, trace and isolate to beat COVID-19
Testing alone does not prevent SARS-CoV-2 infections; minimizing contact with people who have an infection does. However, rapid diagnosis and isolation of people with SARS-CoV-2 infection — whether they have symptoms or not — and aggressive tracing, testing and isolation of their contacts, are key to ensuring safety in Canada’s school, work and social environments. It’s time for our governments to fully invest in “find, test, trace and isolate.”

Scientific consensus on the COVID-19 pandemic: we need to act now
Japan, Vietnam, and New Zealand, to name a few countries, have shown that robust public health responses can control transmission, allowing life to return to near-normal, and there are many such success stories. The evidence is very clear: controlling community spread of COVID-19 is the best way to protect our societies and economies until safe and effective vaccines and therapeutics arrive within the coming months.

Residential context and COVID-19 mortality among adults aged 70 years and older in Stockholm: a population-based, observational study using individual-level data
Compared with living in a household with individuals aged 66 years or older, living with someone of working age (<66 years) was associated with increased COVID-19 mortality (hazard ratio 1·6; 95% CI 1·3–2·0). Living in a care home was associated with an increased risk of COVID-19 mortality (4·1; 3·5–4·9) compared with living in independent housing. Living in neighbourhoods with the highest population density (≥5000 individuals per km2) was associated with higher COVID-19 mortality (1·7; 1·1–2·4) compared with living in the least densely populated neighbourhoods (0 to <150 individuals per km2).
