Oh, OK. If that's the case, not such good news as I originally thought. Doesn't offer a lot of health benefits - just means that people with a common cold or ordinary cough can go back to work and don't need to self-isolate. Useful to the economy, of course, which is a good thing, but still...
Don't get that. If you or your partners are key workers you may be in contact with a lot of people, maybe vulnerable ones - so if you've got totally asymptomatic CV19 is it a good idea to not waste the time of the testers and go on spreading it?
