COVID-19 Literature Situation Report March 23, 2020

Category:

The scientific literature on COVID-19 is rapidly evolving and these articles were selected for review based on their relevance to Washington State decision making around COVID-19 response efforts. Included in these Lit Reps are some manuscripts that have been made available online as pre-prints but have not yet undergone peer review. Please be aware of this when reviewing articles included in the Lit Reps.

Key Takeaways

  • While highly disruptive to society, a study found four social distancing interventions to be highly effective in flattening the curve, even after a 10-week delay from index case arrivals. 
  • Another study highlights the importance of using telehealth to deliver care and shares strategies on integrating telehealth into the general healthcare system.
  • A couple of studies describe the use of AI and machine learning-based diagnosis tools used in China, which could be considered for faster and extensive COVID-19 screening capabilities. 
  • A report shares 10 key recommendations for management of COVID-19 during pregnancy. 
  • Two studies review the effectiveness of COVID-19 treatments: one indicates convalescent plasma (CP) therapy may have a potential therapeutic effect on severe cases; the other suggests potential safety concerns related to ribavirin.

Article Summaries

Non-Pharmaceutical Interventions

The Effectiveness of Social Distancing in Mitigating COVID-19 Spread: a modelling analysis

  • By adapting an established simulation model based on the infection history of individual cases, the authors find that application of 4 social distancing interventions (school closure, workplace non-attendance, increased case isolation and community contact reduction) is highly effective in flattening the epidemic curve.
  • These interventions were found to be effective even 10 weeks after the first index cases. The most effective intervention was increasing case isolation to 100% of children and 90% of adults. 
  • While effective, these interventions are highly disruptive to society and creates challenges for government officials, who need to consider what the population can sustain.

Public Health Responses to COVID-19 Outbreaks on Cruise Ships —Worldwide, February–March 2020

  • Outbreaks of COVID-19 on cruise ships pose a risk for rapid spread of disease beyond the voyage. Transmission occurred from crew members and passengers, and from ship to ship by crew members. Aggressive efforts are required to contain spread. 
  • Everyone should defer all cruise travel worldwide during this outbreak.

Testing and Treatment

The feasibility of convalescent plasma therapy in severe COVID- 19 patients: a pilot study

  • Results from a pilot study based on 19 severe COVID-19 patients indicate that convalescent plasma therapy may have a potential therapeutic effect and low risk in the treatment of severe cases.

Effectiveness and safety of antiviral or antibody treatments for coronavirus.

  • The authors conducted a comprehensive literature review on the effectiveness and safety of antiviral therapies for COVID-19 and found that the current evidence on the effectiveness and safety of antiviral therapies is inconclusive. In particular, ribavirin has not shown conclusive effectiveness and may cause harmful adverse events.

AI-assisted CT imaging analysis for COVID-19 screening: Building and deploying a medical AI system in four weeks

  • The authors describe their experience in building and deploying an AI system in China that automatically analyzes CT images to detect COVID-19 pneumonia features for faster examination. They report high sensitivity (97%) and high specificity (92%) using the test dataset. 
  • Authors of another study on AI applications for COVID-19 provide a machine learning based diagnosis model using 620 lab samples, which could facilitate extensive COVID-19 screening.

Mental Health and Personal Impact

How health anxiety influences responses to viral outbreaks like COVID-19: What all decision makers, health authorities, and health care professionals need to know

  • Psychological factors play a vital role in the success of public health strategies (risk communication, vaccination and antiviral therapy, hygiene practices, and social distancing) used to manage outbreaks like COVID-19.
  • It is critical for public health decision-makers, health authorities and health care providers across disciplines to understand how health anxiety may influence individual behaviors during COVID-19. This will help tailor messages that may curb irresponsible decisions by the general public.
