Things are still getting worse. The US death toll crossed 14,000 on Wednesday, with a record 1,858 deaths reported just on Tuesday. Since the outbreak started, about 425,000 cases have been diagnosed in the US. And researchers say the peak has yet to come. But the main model used by the White House and pretty much everyone else was updated Wednesday to show far fewer projected US deaths from Covid-19 -- down to 60,415 people by August, from the 82,000 the model showed on Tuesday (which was already lower than previous projections). New data on the pandemic's trajectory -- from the United States and around the world -- has been fed into the model almost every day, driving the changes. And the downward adjustment suggests that social distancing may be working better than expected in some places.
