The U.S. is seeing a dangerous increase in coronavirus cases in the South and West. As the nation pushes forward with re-opening, half of all states are now averaging more new cases each day than they have in weeks. A fifth of new infections globally are in the U.S. Florida and Texas are setting records for positive tests, and their governors are warning they may need to crack down on people who aren't social distancing. Florida Governor Ron DeSantis acknowledges that increased testing alone can't account for recent record numbers of new COVID-19 cases. He says he'll crack down on businesses that don't follow social distancing guidelines, but adds he won't change the state's reopening plan or enact a state-wide mandatory mask order. With Florida topping 100,000 cases Monday, more younger people are testing positive. Doctors are sounding the alarm.
