A CDC study published on JAMA shows that People without symptoms spread SARS-CoV-2 in more than half of cases.

A model developed by CDC researchers estimates that 59% of coronavirus cases in the United States are spread by asymptomatic carriers. Transmissions from individuals who have not yet begun to exhibit signs of infection account for 35% of that total, while transmissions from people who never develop symptoms make up the other 24%. A model

Study finds higher burden of acute brain dysfunction for COVID-19 ICU patients

COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure. Choice of sedative medications and curbs on family visitation played a role in increasing acute brain dysfunction for these patients. That’s

For U.K. health officials, Interleukin-6 inhibitors (Tocilizumab or Sarilumab) should be prescribed to adult patients admitted to ICU with Covid-19 pneumonia.

Clinicians should consider prescribing intravenous tocilizumab following the criteria defined below for patients in intensive care. Intravenous sarilumab could be considered as an alternative (if available).Any provider organisation treating patients with this intervention will be required to assure itself that the internal governance arrangements have been completed before either medicine is prescribed. These arrangements may
