Very interesting. Some caveats need to be considered. Originally, testing was intended to enable isolating carriers so as to slow the rate of spread and 'flatten the curve,' reducing the strain (and overwhelming) of medical resources. This perspective was in the United States, and even in recent times despite substantial vaccinations, there is a severe strain in some areas (to the extent there are arrangements in place to deploy National Guardsmen to assist some). Flattening the curve still doesn't sound so bad. All the more so, since we don't yet have approval for use of any COVID-19 vaccine in kids under age 12.
And that's in America. Considering the matter in Indonesia is a very different situation. But our answer may be irrelevant; from what Indah's posted before, testing was, is and will likely remain quite limited, and viral spread will rage on.
