There are some difference in opinions between CDC and WHO from what I hear: WHO reccomends a more aggressive early containment strategy, while CDC seems to prefer softer social distancing strategies.
My country is adopting WHO strategies, and while likely they will not be sufficient as everybody seems to agree the virus will be with us till at least this summer, for the moment they are working: only very few cases are out of the lock-down hot-spots (they are about a dozen towns for a total population of about 50k people, to give an idea).
People that try to enter or leave the lock-down zones without good reasons and arranging it with the health department would be stopped and fined, but people at least for now are collaborating quite willingly in a disciplined way.
Anyway, in the meantime, all north of Italy schools are closed, and we are starting to deploy distance-learning tools.
In the region around the lock down zones (Lombardy and the Venetian, the most industrialized regions of Italy), all people-gathering activities have been closed, from pubs and restaurants to cinema to gyms to churches, but in the rest of Italy they are not yet, although attendances are way down.
Monday there were some limited supermarket runs, people wanted to be sure to have some "just in case" reserves of the fundamentals, but the only consequence were some bare shelves: food and resource distribution is going on regularly.
Some of the usual jackals tried to profit from the sudden scarcity of face masks and hand sanitizers with huge price gouging, but it did not last much, pharmacies are already getting fresh batches.
Public transport is still working everywhere, there are some delays as long distance trains get stopped for checks when entering or leaving the dangerous zones.
The companies in the lock-down zone have been temporarily closed, but outside they are only encouraged to shift any worker they can do telecommuting.
Syndicates and emergency government committees are studying all kinds of incentives and facilitations to help transitioning as many people possible to this form of work, and made a decree that ensure no liabilities for companies or workers for the measures taken in the meantime in this direction.
With my own company, we decided to take the chance to triage our "emergency response plan" to ensure the company functioning in case of disruption of our workplace. Its working well, and right now only few employees are working from the office, all the rests moved to distance work.
Right now, to give some numbers from a western country, we have tested around 5000 symptomatic or at risk people, finding a total 374 positive cases, and 12 deaths, all of over 60 (mostly 80+) and suffering from pre-existing conditions.
The official percentages told by WHO doctors on official public sources here are that 80% of infected are barely symptomatic, 15% develop serious symptoms, 5% develop life threatening symptoms, and a still unclear percentage of these if vulnerable for other reasons may die.
Of course in the media chaos there are also doctors that say that's barely more serious than normal flu and everybody is being too overdramatic and we should think of the economy, and pundits that predict the end of the nation if we don't kick out all immigrants immediately and close all our borders.
But most of the chaos (for the moment) is in the media: from what I can see and what I can infer reading between the attempts of the media to dramatize things, people seems to be taking things calmly and rationally, even more so than before these things happened.
