US coronavirus deaths rose by over 25,000 in July and cases doubled in 19 states during the month, according to a Reuters tally, dealing a crushing blow to hopes of quickly reopening the economy.
Cases also more than doubled in Alabama, Alaska, Arizona, Arkansas, Georgia, Hawaii, Idaho, Mississippi, Missouri, Montana, Nevada, Oklahoma, Oregon, South Carolina, Tennessee and West Virginia, according to the tally.

After a rapid acceleration in cases, the outbreak appears to be stabilizing in Arizona, Florida and Texas. Health officials are now concerned the outbreak has migrated to the Midwest from summer travel.
The news that more states could be hard hit by the virus comes a day after the US reported that gross domestic product collapsed at a 32.9% annualized rate in the second quarter, the nation's worst economic performance since the Great Depression.
