Florida’s confirmed coronavirus cases rose by a record 11,458 on Saturday, the state’s health department said, the second time in three days that its caseload increased by more than 10,000. In just the first four days of July, 14 states have posted a daily record increase in cases of Covid-19, the disease caused by the coronavirus that has killed nearly 130,000 Americans. The recent surge, most pronounced in southern and western states, has alarmed public health officials, who urged caution ahead of the holiday weekend to celebrate the Declaration of Independence of the United States in 1776. Florida’s record rise in cases was more than any European country’s daily peak at the height of the outbreak there. North Carolina, South Carolina, Tennessee, Alaska, Missouri, Idaho and Alabama all registered new daily highs on Friday, while Texas hit a new peak for hospitalisation. The daily US tally of cases stood at 53,483 late on Friday, below the previous day’s record 55,405. Globally, the World Health Organisation reported a record 212,326 new coronavirus cases in the 24 hours ended early Saturday, the first infection total to top 200,000. The WHO has reported more than 163,000 new cases every day for the past week, led by the rise in the Americas Despite the jump in infections, the average daily death toll in the United States has gradually declined in recent weeks, a reflection of the growing proportion of positive tests among younger, healthier people who are less prone to severe outcomes. Evidence the surge is not simply due to expanded testing, the percentage of tests coming back positive in Florida rose to 14.8 per cent in the past two weeks compared to 8.3 per cent the two weeks prior, according to a Reuters analysis. The World Health Organisation says a rate over 5 per cent is concerning. Against that backdrop, Miami-Dade County Mayor Carlos Gimenez imposed an indefinite nightly curfew starting Friday and halted the reopenings of entertainment venues such as casinos and strip clubs. Earlier this week, Miami-Dade and neighbouring Broward County, the state’s two most populous counties, required residents to wear face coverings in public. Arkansas on Friday joined a push toward mandating mask-wearing in public, with Governor Asa Hutchinson authorised the state’s cities and towns to enact a “model ordinance” requiring the wearing of face coverings if they choose to do so.

President Donald Trump has repeatedly sought to dismiss the jump in confirmed cases as a function of more tests and again this week predicted that the virus would “disappear.” “If you test 40,000,000 people, you are going to have many cases that, without the testing (like other countries), would not show up every night on the Fake Evening News,” Trump wrote on Twitter on Saturday.
