The United States hit an all-time high in new coronavirus cases on Friday, surpassing the previous mark set during a summer surge across the Sun Belt. Friday’s tally of new U.S. cases — the first above 80,000 — comes as covid-19 hospitalizations are soaring across the country; according to data tracked by The Washington Post, the average number of hospitalizations has jumped in at least 38 states over the past week, a trend that cannot be explained by more widespread testing.

Fourteen states have reported new highs in hospitalized covid-19 patients in the past seven days: Kentucky, Nebraska, Ohio, Oklahoma, South Dakota, Tennessee, Wisconsin, Wyoming, Iowa, Utah, Montana, West Virginia, Missouri and Kansas. Health experts say the current wave is setting the stage for an even greater surge heading into colder months.

Here are some significant developments:

  • The Johnson & Johnson coronavirus vaccine trial, paused because of a participant’s unexplained illness, will resume soon, and a vaccine candidate from AstraZeneca and Oxford University has been cleared to restart trials in the United States.
  • Data from a project tracking real-time coronavirus statistics yields a particularly vivid illustration of how mask usage influences the prevalence of covid-19 symptoms in a given area. See it here.
  • Treasury Secretary Steven Mnuchin delivered a downbeat assessment Friday about his economic stimulus talks with House Speaker Nancy Pelosi (D-Calif.), saying “significant differences” remain.
  • The governor of Italy’s third-most-populous region said Friday that he is enacting a strict lockdown, reimposing the rules of March and April that brought life to a standstill.
  • The Trump administration has been pressuring health experts at the Centers for Disease Control and Prevention to endorse the use of border hotels to hold migrant children before deporting them, according to federal health officials.
  • A travel group report says flying is safe. The doctor whose research it cited says not so fast.
