Health experts have long warned about a second peak in Covid-19, and now a rise in cases has pushed Arizona to tell its hospitals to activate emergency plans. Arizona is one of the 19 states with the trend of new coronavirus cases still increasing. While 24 are trending downward, seven states' trends are holding steady. Nationally more than 1.9 million people have been infected by the virus and more than 112,000 have died, according to data from Johns Hopkins University. At its peak, Arizona's intensive care unit beds were 78% in use. As of Monday, 76% were occupied.
