I do not think you use the term "disease case" correctly. Please read the important CDC paper on the EPIC study (Etiology of Pneumonia in Communities) - https://www.nejm.org/doi/pdf/10.1056/NEJMoa1500245
Etiology of pneumonia did not suddenly change from 62% unknown and the rest caused by bacteria and several viruses to 100% SARS-CoV-2. Please see what kind of samples were analyzed in this study and note that, according to the CDC in the good old days, nasopharyngeal swabs should not be used to diagnose viruses by using PCR.

I expect masks in public makes contact tracing more useful as masks tend to mostly reduce untraceable transmission.
Perhaps population susceptibility, not the exposure controls, was the dominant factor that separated different countries.
Perhaps populations in that part of the world had prior exposure to viruses similar to the initial COVID strains, but not to Omicron.
“It shows us that TTI is extremely effective when it is done properly”
Maybe, maybe not. Evidence to the contrary abounds. Yours isn’t the sober data driven conclusion you represent it to be.
