COVID-19 – Infection Prevention and Control literature – January 2021

Papers that related to COVID-19 infection prevention and control from the daily COVID-19 Critical Intelligence Unit  listings and other identified literature.  This posting does not assess the specific evidence or its quality. Please let me know of any gaps – @mdjkf .

Peer reviewed journals

  • An experimental study on the stability of SARS-CoV-2 on critical personal protective equipment here  “…viable SARS-CoV-2 in the presence of a soil load persisted for up to 21 days on experimentally inoculated PPE, including materials from filtering facepiece respirators (N-95 and N-100 masks) and a plastic visor. Conversely, when applied to 100% cotton fabric, the virus underwent rapid degradation and became undetectable by TCID50 assay within 24 h. “
  • An observational study on aerosol-based transmission of SARS-CoV-2 in hospital rooms and community isolation facilities here “While SARS-CoV-2 is readily captured in aerosols, virus culture remains challenging despite optimized sampling methodologies to preserve virus viability.”
  • A simulation study on fluid dynamics of COVID-19 airborne infection here A complex study:  “Our simulations demonstrate that currently available information is inadequate to design social distancing recommendations on a solid scientific basis. … The relative humidity of the environment has a particularly dramatic effect [on droplet size and transmission potential].” , 
  • Unintended consequences of hand sanitiser use in COVID-19 pandemic here  “…JAMA Ophthalmology, authors1,2 from 2 different countries report eye injuries in children from inadvertent contact with alcohol-based hand sanitizer. Martin et al1 found a 7-fold increase in ocular exposure in children in 2020, with a corresponding increase in surgeries required to manage severe injuries resulting from these exposures.”
  • Recommendations for residential aged care in Australia post-COVID-19 here  [ a perspective from Victoria, pre second wave ]

Editorials, Commentaries & correspondence

  • Dismantling myths on the airborne transmission of severe acute respiratory syndrome coronavirus (SARS-CoV-2) Dancer et al  here [a useful survey of several misunderstood concepts] 

  • Airborne Transmission of SARS-CoV-2: What We Know Samet et al here 

  • The COVID-19 response in Australia here    “… Catherine Bennett, Deakin University’s chair in epidemiology at the Institute for Health Transformation, says the test and trace system in Melbourne failed during lockdown. ‘We were struggling to get the testing regime working: the results weren’t coming back quickly enough for the contact tracers to act, and then the tracers were overwhelmed. It was the difference between documenting an outbreak and bringing case numbers down and stopping new outbreaks.’  In April the whole of Victoria had just 57 contact tracers including public health clinicians, logisticians, phone operators, and data entry staff. As the crisis worsened the state government was forced to increase staffing to over 2000.”
