The medical journal Lancet published a statement from the authors of a study showing that hydroxychloroquine was dangerous for hospitalized covid-19 patients, saying they were unable to complete an independent audit of the hospital data underpinning their analysis. As a result, they concluded they “can no longer vouch for the veracity of the primary data sources.”

The study, purportedly based on the health records of almost 100,000 patients around the world, found that hospitalized covid-19 patients treated with the antimalarial drug hydroxychloroquine — a drug repeatedly touted by President Trump — had a sharply higher risk of death and heart-rhythm problems compared to those who did not receive the drug.

Here are some significant developments:

  • The director of the Centers for Disease Control and Prevention told a House panel Thursday that demonstrators protesting racial injustice need to get tested for the coronavirus.
  • Two countries on Thursday reported alarming increases in coronavirus cases. Brazil confirmed a record number of deaths on consecutive days, more than 2,600 in that time, and now has at least 584,000 confirmed cases of covid-19. And Iran, which was hard hit earlier this year but began lifting lockdown restrictions April 11, reported a record 3,574 new confirmed cases over the past 24 hours, raising concerns of a second wave of infections.
  • The number of Americans filing for unemployment benefits decreased to 1.9 million for the last week of May, the fewest since the novel coronavirus started spreading widely in March but more than analysts forecast. Though it is a sign the economy may no longer be in free fall, recovery could be long and difficult.
  • Iran released U.S. Navy veteran Michael White, a California native who had contracted the coronavirus and had been held for nearly two years. Due to several complicating health conditions, White’s family feared for his life in Iran’s notoriously cramped and unsanitary prison system.
