Estimating Salivary Carriage of Severe Acute Respiratory Syndrome Coronavirus 2 in Nonsymptomatic People and Efficacy of Mouthrinse in Reducing Viral Load. Authors of this article undertook two studies to understand levels of SARS-CoV-2 in the saliva of potential dental patients and to test how well mouthrinses worked to lower the virus levels. These studies revealed two key findings:

1. Saliva caries a high rate of virus in nonsymptomatic patients, although low enough that the likelihood of transmission is also low.

2. A mouthrinse of 1% hydrogen peroxide, 0.12% chlorhexidine, or 0.5% povidone-iodine for 60 seconds works well to reduce virus levels in saliva for up to 45 minutes.

The Physiological Burden of Prolonged PPE Use on Healthcare Workers during Long Shifts. This blog from the National Institute for Occupational Health and Safety (NIOSH) reports that healthcare personnel who have adopted the regular use of N95 filtering facepiece respirators (FFRs), elastomeric half-mask respirators, and powered air-supplied respirators (PAPRs) may experience a variety of physiological effects from wearing the personal protective equipment (PPE) throughout long shifts. These include:

  • Headache
  • Increased pressure inside the skull
  • Nervous system changes
  • Increased breathing frequency
  • Increased “work of breathing”
  • Cardiovascular effects
  • Reduced tolerance to lighter workloads

The authors share that there are several steps healthcare management and personnel can take to avoid experiencing negative effects from prolonged PPE use. To learn about the steps to you can take, click here. (Updated January 25, 2021)
