But the situation would have been much worse had states not shut down, a new study says.
More than 1.9 million Americans have been infected, and more than 116,000 have died in just over four months, according to data from Johns Hopkins University.
Nationwide, 22 states are seeing upward trends in coronavirus cases. About 20 states have seen decreases in recent days, and eight states are holding steady.
One of the states with the biggest spikes in new cases is Florida. The number of new cases reported each day has increased an average of roughly 46% over the past week, just as most of the state entered a second phase of reopening.
And there's global proof that the coronavirus pandemic is nowhere near over.
Sunday marked the most Covid-19 cases reported to the World Health Organization in a single day during this pandemic, WHO Director-General Tedros Adhanom Ghebreyesus said.
