Look at the science rather than knee jerk reactions from foreign politicians who want to be seen to be doing something. We are past containing it, it's too virulent so we should expect most people to catch it, herd immunity then can protect the most vulnerable who should be quarantined now. If you have kids with underlying health conditions keep them off, similarly if you have moderate to severe asthma for instance, distance yourself now, for the rest of us, wash your hands, keep calm and carry on.
Disclaimer, I'm not personally a scientist but my good friend is and is in charge of the response at our local county council. This has worked for other outbreaks of similar diseases.
