Most jurisdictions outside of China haven't been locked down long enough for us to say with any level of certainty that the epidemic's growth curve is being bent.New cases and deaths were down worldwide yesterday, which hopefully is reflective of all the lockdowns.
About the only place where there's some observed effect thus far is King County, WA.
Maybe you can count Italy as they are coming up on 3 weeks, and new confirmed cases are no longer growing.
If you're talking global cases and death toll, we're at the tip of the iceberg with many highly populous countries yet to experience the high growth phase of the pandemic. Any dip yesterday is maybe just a function of Sunday having less data to report (in some parts of the world, not the U.S.).
