Hospitals rapidly approached capacity across the Sunbelt, and the Miami area closed restaurants and gyms again because of the surging coronavirus Monday, as the U.S. emerged from a Fourth of July weekend of picnics, pool parties and beach outings that health officials fear could fuel the rapidly worsening outbreak. Confirmed cases are on the rise in 41 out of 50 states plus the District of Columbia, and the percentage of tests coming back positive for the virus is increasing in 39 states. Florida, which recorded an all-time high of 11,400 new cases Saturday and has seen its positive test rate lately reach more than 18%, has been hit especially hard. A virus outbreak in the California Legislature indefinitely delayed the state Assembly’s return to work from a scheduled summer recess. Coronavirus hospitalizations in California have increased 56% in the past two weeks while the number of confirmed cases has jumped 53%. Hospitalizations across Florida have been ticking upward, with nearly 1,700 patients admitted in the past seven days compared with 1,200 the previous week. Five hospitals in the St. Petersburg area were out of intensive care unit beds, officials said. Miami’s Baptist Hospital had only four of its 88 ICU beds available. Officials in Texas also reported hospitals are in danger of being overwhelmed. Hospitalizations statewide surged past 8,000 for the first time over the weekend, a more than fourfold increase in the past month. Houston officials said intensive care units there have exceeded capacity.
