Hopes for a new stimulus package to help ease the economic stress of the pandemic before the November elections waned Thursday after Democrats blocked a slimmed-down coronavirus relief bill put forward by GOP leaders. Many of the benefits created in the Cares Act passed by Congress in March have already expired, and about 29 million Americans drew jobless aid last week, according to Labor Department data.

Here are some significant developments:
  • new research letter from Harvard University researchers suggests the risk to young people has been undersold, after a study of 3,222 hospitalized patients age 18 to 34 found that 1 in 5 required intensive care, 10 percent needed a ventilator, and 2.7 percent died. An additional 3 percent required ongoing medical care even after clearing the virus.
  • The U.S. coronavirus death toll has surpassed 188,000, and at least 6,366,000 cases have been reported.
  • U.S. airports will stop checking international travelers for fevers before allowing them to enter the country after a review of the procedure found that only 15 coronavirus cases were detected among 675,000 people screened.
  • An unusually large number of patients in Los Angeles complained about coughs between December and February, according to a new report published Thursday in the Journal of Medical Internet Research, raising the possibility that the novel coronavirus may have been spreading in the United States earlier than previously thought.
  • Regulators fined two food-processing plants Thursday for failing to adequately protect workers from coronavirus risks, leveling penalties ranging from $13,494 to $200,000 following employee deaths.
