The United States surpassed 170,000 coronavirus deaths on Sunday, according to a Reuters tally, as health officials express concerns over COVID-19 complicating the fall flu season. Deaths rose by 483 on Sunday, with Florida, Texas and Louisiana, leading the rise in fatalities. The United States has at least 5.4 million confirmed cases in total of the novel coronavirus, the highest in the world and likely an undercount as the country still has not ramped up testing to the recommended levels. Cases are falling in most states except for Hawaii, South Dakota and Illinois. Public health officials and authorities are concerned about a possible fall resurgence in cases amid the start of the flu season, which will likely exacerbate efforts to treat the coronavirus.
