July 3 | Daily COVID-19 LST Report


  • A medical ethicist discusses unique ethical dilemmas that the COVID-19 pandemic has presented including individual rights vs public good, data collection, resource rationing, and vaccine trials.


  • Age demographics and travel histories of confirmed COVID-19 cases: Authors from the Hong Kong University of Science and Technology found that the largest incidence of positive cases occurred in the 15-24 age group (41%). Furthermore, (61%) had traveled to countries with known outbreak or been exposed to other infected travelers. These findings emphasize risk of transmission among younger, less symptomatic individuals and reveal the importance of travel restrictions/precautions during the pandemic.

  • A retrospective cohort study from China (n=104) analyzed predictors of severe VID-19 disease based on initial presentation. They found that older age (>63 years [odds ratio, OR=41.0; 95% CI: 2.8, 592.4]), decreased lymphocyte count (≤1.02×10^9/L [OR=6.1; 95% CI: 1.5, 25.2]), and elevated serum CRP (≥65.08 mg/L [OR= 8.9; 95% CI = 1.0, 74.2]) are key early predictors of severe disease.

  • Neurological effects of COVID-19: Nature Reviews Neurology highlights the significant evidence of CNS damage in COVID-19, noting the wide range of symptomatology and still undetermined mechanism injury.

  • Cytokine release syndrome (CRS) in COVID-19: Data from 11 patients with acute respiratory distress syndrome (ARDS) in Guangzhou, China indicated that 8/11 patients developed CRS with characteristics including a continuous fever, end-organ dysfunction, and coagulopathy. A substantial increase of interleukin 6 (IL-6) suggests it may act as a prognostic factor for CRS development in COVID-19 patients with severe pneumonia.
