Researchers analyze acute and post-acute COVID-19 presentations in athletes

Researchers at the University of São Paulo (USP) in Brazil analyzed data from 43 scientific articles describing the effects of COVID-19 on athletes and concluded that while the disease was asymptomatic or mild in the vast majority of cases (94%), about 8% of the subjects concerned had persistent symptoms affecting their performance and potentially preventing a return to training and competing.

Feds want a policy that advocates say would let hospitals off the hook for covid-era lapses

The Centers for Medicare & Medicaid Services is responding to the chaos of the covid-19 pandemic by proposing to hide from the public a rating that lets consumers compare hospitals' safety records and to waive approximately $350 million in financial penalties for roughly 750 hospitals with the worst patient-safety track records.
