While deaths from the coronavirus in the US are mounting rapidly, public health experts are seeing a flicker of good news: The second surge of confirmed cases appears to be leveling off. Scientists aren´t celebrating by any means, warning that the trend is driven by four big, hard-hit places – Arizona, California, Florida and Texas – and that cases are rising in close to 30 states in all, with the outbreak’s center of gravity seemingly shifting from the Sun Belt toward the Midwest. Some experts wonder whether the apparent caseload improvements will endure. It’s also not clear when deaths will start coming down. COVID-19 deaths do not move in perfect lockstep with the infection curve, for the simple reason that it can take weeks to get sick and die from the virus. The future? “I think it´s very difficult to predict,” said Dr. Anthony Fauci, the government’s foremost infectious-disease expert. The virus has claimed over 150,000 lives in the US, by far the highest death toll in the world, plus more than a half-million others around the globe. Over the past week, the average number of COVID-19 deaths per day in the US has climbed more than 25%, from 843 to 1,057. Florida on Thursday reported 253 more deaths, setting its third straight single-day record, while Texas had 322 new fatalities and California had 391. The number of confirmed infections nationwide has topped 4.4 million, which could be higher because of limits on testing and because some people are infected without feeling sick. In other developments: The collateral damage from the virus mounted, with the US economy shrinking at a dizzying 32.9% annual rate in the April-June quarter – by far the worst quarterly plunge on records dating to 1947. And more than 1.4 million laid-off Americans applied for unemployment benefits last week, further evidence that employers are still shedding jobs five months into the crisis. – Amid the outbreak and the bad economic news, President Donald Trump for the first time publicly floated the idea of delaying the Nov. 3 presidential election, warning without evidence that increased mail-in voting will result in fraud. Changing Election Day would require an act of Congress, and the notion ran into immediate resistance from top Republicans and Democrats alike. – Herman Cain, the former pizza-chain CEO who in 2012 unsuccessfully sought to become the first Black candidate to win the Republican nomination for president, died of complications from the virus at 74. Based on a seven-day rolling average, daily cases of the coronavirus in the US fell from 67,317 on July 22 to 65,266 on Wednesday, according to data kept by Johns Hopkins University. That is a decline of about 3%.
