We don't need one method to stop all transmissions. Some will be stopped with a temperature check, some by masks, some by symptomatic people staying home, some by washing hands, etc. The goal is for all of those "somes" to add up to infected people, on average, transmitting it to fewer than 1 other person. That will lead to it eventually dying out.
