Meantime, a scientific model predicts there will be a rapid spike in coronavirus cases in states that reopened the earliest. Research has also suggested those states that lifted restrictions slowly might escape an immediate second wave.</s>SCIUTTO: This comes as California, which remains on a partial lockdown, has reported its second highest one-day death toll. CNN's Dan Simon has been following this and he joins us now from San Francisco. How big a spike and what do officials there attribute the spike to?</s>DAN SIMON, CNN CORRESPONDENT: Well, there is a spike, and we saw this on Tuesday as you said, the second highest death toll. They don't really know what to make of it. What they do say though is that they are seeing fewer cases and fewer hospitalizations. So the data seems to be going in the right direction, and it's full steam ahead in terms of the reopening. The governor says he has the confidence to allow more and more communities to reopen. So now, you have about half of the counties throughout the State of California. END
