TL;DR: In this article, a semi-analytical model was proposed to identify two tipping points between controlled and uncontrolled SARS-CoV-2 spread: (1) the behavior-driven reproduction number of the hidden chains becomes too large to be compensated by the TTI capabilities, and (2) the number of new infections exceeds the tracing capacity.

TL;DR: The results suggest that TTI alone is insufficient to contain an otherwise unhindered spread of SARS-CoV-2, implying that complementary measures like social distancing and improved hygiene remain necessary.

TL;DR: In this article, the authors examined key aspects that are likely to influence the COVID-19 pandemic in Europe, including progress of national and global vaccination programs, emergence and spread of variants of concern (VOCs), and public responses to non-pharmaceutical interventions (NPIs).

TL;DR: In this paper, an age-stratified SEIRD-ICU compartmental model and curated epidemiological and vaccination data were used to quantify the rate at which countries can lift non-pharmaceutical interventions without overwhelming their healthcare systems.

TL;DR: This work analytically derives the existence of a third, viable solution: a stable equilibrium at low case numbers, where test-trace-and-isolate policies partially compensate for local spreading events, and only moderate contact restrictions remain necessary, and minimises lockdown duration and hence economic impact.
