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.<\/p>\n
Today’s summary is based on a review of 175 articles (46 published, 129 in preprint)<\/em><\/p>\n \t\t\t\t<\/p>\n [Preprint, not peer-reviewed] <\/i>A participant\u2019s behavior during behavioral simulation of social distancing behaviors was associated with the risk of subsequently contracting COVID-19, whereas self-report of these behaviors was not. Results from a survey among 2,120 US residents determined that an individual\u2019s performance in a simulator intended to assess physical positioning was associated with lower risk of COVID-19 illness over the subsequent 4 months (OR=0.8), but self-reports of social distancing behavior did not show a significant association with infection of SARS-CoV-2. This association was maintained when considering only participants who were positive for SARS-CoV-2 and when considering participants who were untested but believed that they had been infected.\u00a0<\/span><\/p>\n Fazio et al.

Hispanic ethnicity (OR=1.5) and having an infected sibling close contact (OR=1.7) were associated with increased infection risk. One or more symptoms were reported by 70% of children who were positive for SARS-CoV-2. Children ages 6-13 years were frequently asymptomatic (39%) and less likely to report respiratory symptoms than younger children ages 0-5 years or adolescents ages 14-20 years (29% vs. 48% and 60%, respectively). No difference was found in viral load between various age cohorts. [EDITORIAL NOTE: A pre-print version of this article was summarized on August 24]<\/i><\/p>\n Hurst et al. (Nov 3, 2020).

Using census tract- and parish-level data in Louisiana, Schnake-Mahl et al. reported that the incidence (73 cases per 10,000) and mortality rate (5.6 deaths per 10,000) of COVID-19 were initially highest in New Orleans during the first wave of the epidemic which occurred during March-April 2020. During the period of July-September 2020, trends reversed with suburban\/rural areas experiencing higher rates than New Orleans. During the second peak, suburban and other urban areas had incidence rates over 70 cases per 10,000, nearly double the rate in New Orleans. Since May, positivity ratios have hovered close to 10% in other urban, suburban, and rural areas while remaining below 5% in New Orleans. Social vulnerability was associated with increased positivity and incidence during the first peak, and these disparities were ameliorated during re-opening and the second peak.\u00a0<\/span><\/p>\n Schnake-Mahl et al.
