Updates & Corrections

  • Correction 17 December 2020: An earlier version of this feature referred to the wrong guidance from the WHO on quarantining contacts in designated facilities. It should have referred to guidance issued in February, not August. The text and reference 4 have been updated accordingly. Furthermore, it erred in stating that the WHO declared COVID-19 a pandemic.
