Given that individuals may make health decisions based on mass media coverage, and given that such decisions have broad consequences in the case of highly contagious infectious disease, it is imperative that public health practitioners are aware of mass media coverage on emerging health threats such as COVID-19. The purpose of this study was to examine the content of news segments covering COVID-19 posted on-line.

ABSTRACTObjective:The purpose of this study was to assess the readability of information on the Internet posted about coronavirus disease 2019 (COVID-19) to determine how closely these materials are written to the recommended reading levels.Methods:Using the search term “coronavirus,” information posted on the first 100 English language websites was identified. Using an online readability calculator, multiple readability tests were conducted to ensure a comprehensive representation would result.Results:The mean readability scores ranged between grade levels 6.2 and 17.8 (graduate school level). Four of the 5 measures (GFI, CLI, SMOG, FRE) found that readability exceeded the 10th grade reading level indicating that the text of these websites would be difficult for the average American to read. The mean reading level for nearly all noncommercial and commercial websites was at or above the 10th grade reading level.Conclusions:Messages about COVID-19 must be readable at an “easy” level, and must contain clear guidelines for behavior. The degree to which individuals seek information in response to risk messages is positively related to the expectation that the information will resolve uncertainty. However, if the information is too complex to interpret and it fails to lead to disambiguation, this can contribute to feelings of panic.

Animal and human studies demonstrate an association between smaller hippocampal volume and stress. A composite index of peripheral biomarkers used to objectively quantify human psychosocial stress has demonstrated utility, but has not yet been linked to hippocampal volume in putative ‘high stress’ groups. Structural magnetic resonance imaging exams and a composite of biomarkers representing cardiovascular, atherosclerosis, hypothylamic-pituitary-adrenal axis, glucose metabolism, and sympathetic nervous system activity were assessed in 30 healthy women with histories of stress precipitated by their child's diagnosis of a life-threatening illness. Hippocampal volume was significantly predicted by age, time since stressor onset, and the composite. An objective biomarker index may improve temporal tracking of brain changes in relation to stress-related psychological symptoms, with implications for basic and clinical research.
