I lived in a place that did contact tracing for SARS-Cov-2 and it definitely worked. Other places in Canada had large outbreaks they had to quell with extensive lockdowns to prevent hospital overwhelm.
Nova Scotia did extensive contact tracing when a case first appeared and often could get rid of small outbreaks without additional measures (beyond border controls.)
The spread of SARS and MERS around the world was via airplanes. That doesn’t mean they for firmly established in any population.
- timr 4y agoIn literally every part of the world, SARS-CoV2 is endemic. It didn't "work", you're just making a post hoc attribution of wiggles in the first derivative of case counts to an action that you prefer. A far more parsimonious reason that (for example) Novia Scotia had fewer cases (for a time) is that Novia Scotia is in the middle of nowhere and has less than a million people. It's the inverse of the reason that the major cities of the world got it first.
