As I recall, Vietnam completely missed a hospital outbreak in a major tourist destination (having restarted internal tourism some time earlier) until someone who'd visited a patient at the hospital with no other plausible source of infection happened to get tested and came back positive. And then covered up that, their first detected case in a good while, for about a week whilst they searched for ways to blame it on foreigners and failed. Western countries tend to have pretty heavy testing in and around hospitals because they know how bad Covid getting in could be.
