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 398 articles (333 published, 65 in preprint)<\/em><\/p>\n \t\t\t\t<\/p>\n The risk of SARS-CoV-2 infections and outbreaks were low in educational settings since reopening in the summer half-term in England, with the likelihood of a school outbreak strongly associated with the regional level of COVID-19 incidence. A prospective cohort study among 57,600 educational settings in England reported that there were 113 educational settings in which a single infected individual was identified, nine settings in which two or more cases were detected within 48 hours (no evidence of a chain of transmission), and 55 outbreaks (at least two epidemiologically linked cases, with sequential cases diagnosed within 14 days in the same educational setting). The outbreaks involved 210 epidemiologically linked cases. This analysis corresponds to a reopening period from June 1-July 17, 2020, with enhanced surveillance after the first national lockdown.\u00a0<\/span><\/p>\n The risk of outbreaks increased by 72% for every five cases per 100,000 population increase in community incidence (p<0.0001). Most cases linked to outbreaks (73% of 210) were in staff members and the median number of secondary cases in outbreaks was 1 (IQR 1\u20132) for student index cases and 1 (IQR 1\u20135) for staff index cases. Staff-to-staff transmission was most common, while\u00a0 <\/span>student-to-student transmission was rare.<\/p>\n Ismail et al. (Dec 9, 2020).

Researchers observed a sharp decline in both depressive symptoms and anxiety as early as the second week of lockdown, suggesting rapid adaptation to circumstances. Although inequalities in mental health experiences persisted for the entire 20-week period, some groups, including women, younger adults, and individuals with lower educational attainment, had faster improvements in symptoms.<\/p>\n Fancourt et al.

A comparative content analysis\u00a0using a 16-element framework, including domains such as bars, restaurants, childcare, and religious gatherings,\u00a0 <\/span>revealed high granularity and nuance between state-level policy taxonomies, with some domains (e.g. restaurants and movie theaters) showing bimodal policy intensity distributions compatible with binary (yes\/no) coding, and some domains (e.g. childcare and religious gatherings) showing broader variability that would be missed without more granular coding. The framework may be useful for describing specific stages of closing and reopening, as well as for comparing the effects of different policies in various areas.<\/p>\n Lane et al. (Dec 8, 2020).

Of these, 113 consisted of a single case, nine involved two or more cases that occurred close enough in time such that secondary infection was unlikely, and 55 involved outbreaks of at least two epidemiologically linked cases. There was a median of 1 secondary case in the outbreaks. The risk of an outbreak was positively associated with the level of community COVID-19 incidence.<\/p>\nKey Takeaways<\/h2>\n
