Highlights

  • US coronavirus deaths topped 100,000 this week as the nation continues to grapple with inconsistent state policies and protocols and a lack of scientific leadership. 
  • Following a rush to reopen their economies, several states are seeing spikes in coronavirus cases, according to the latest New York Times case counts and a Reuters report. 
  • The CDC released guidance for US businesses planning to reopen.
    • Sweeping changes include ventilation checks and hazard assessment, reconfigured employee workspaces, and temperature checks. 
  • Antibody testing remains problematic.
    • The CDC has explained that even in the nation’s hardest hit areas, likely low COVID-19 prevalence rates of more false-positives and fewer false-negatives.
    • E.g., with a prevalence of 5%, a single test with 90% sensitivity and 95% specificity will have positive predictive value of only 48.6%, no better than a coin toss.
  • On the heels of non-peer-reviewed data showing increased mortality rates, the US Department of Veterans Affairs has ratcheted down its use of hydroxychloroquine to treat veterans with COVID-19, according to the Washington Post.
