Can anyone explain to me why in Asia the authorities seem to be going all in with extraordinary containment measures and testing larger groups of people, whilst in Europe and North America the authorities are responding very different? Almost no lock downs, very limited testing etc. In one country a single patient is enough to lock thousands in a hotel or on a cruise ship for days, while in e.g. the Netherlands everyone is assumed to be corona free. You can only get a test if you have a fever, are coughing and have been in contact with a known patient. Either China is hugely overreacting, or we in Europe/US are in deep trouble. There is not a chance the virus can be contained here I think. In the last week he Netherlands has gone from 0 known patients to about ten, which each have probably infected multiple others. E.g. one was in the ICU (not in isolation) for a week just before diagnosed.
