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\u2019s summary is based on a review of 461 articles (428 published, 33 in preprint).<\/p>\n

\u2022 [pre-print, not peer-reviewed] Pan et al. quantified the effectiveness of non-pharmaceutical interventions on the spread of COVID-19 in the United States and found that only the most stringent level of restrictions (e.g, sheltering in place \/ stay-at-home, public mask requirements, or travel restrictions) significantly decreased COVID-19 cases and deaths in the US. These policies achieved at least a 50% reduction in case rates in six days, compared to eight days for the next highest level of policies (e.g. non-essential business closures, suspending non-violent arrests, suspending elective medical procedures, suspending evictions, or restricting mass gatherings of at least 10 people).<\/p>\n

Of the cases, 30 (58%) were among children (median age = 5 years), and 22 (42%) were among adults (20 teachers and 2 parents, median age = 30 years). The majority of affected centers (69%) reported only a single case without apparent secondary transmission. Secondary transmission was suspected in four childcare centers, including in one in which an investigation revealed a lack of adherence to the guideline prohibiting switching between groups of children.<\/p>\n Link-Gelles et al.

The prototype had higher sensitivity than the control swabs (91% vs. 81%). Alghounaim et al. (Aug 12, 2020).

Responses were persistent, and in some cases increased over three months following symptom onset. They also found that SARS-CoV-2-specific memory lymphocytes exhibited characteristics associated with potent antiviral immunity. The authors conclude that these findings provide evidence that recovered individuals will be protected from a second SARS-CoV-2 infection and that Th1 memory should be the target of vaccine elicited memory.<\/p>\n Rodda et al.

There was a rise in telehealth use from 0.2% to 2% in March 2020 compared to a similar time period in 2019. Adults over 45 were less likely to use telehealth than adults under 45, and respondents living in urban areas were more likely to use telehealth than those living in rural areas. Although presence of anxiety or depression were major predictors of telehealth use compared with in-person visits, no significant differences by sex, ethnicity, socioeconomic behaviors, or health behaviors were observed.<\/p>\n Jaffe et al.

In the African Region (median age: 18.9 years), the authors estimated a median R0 of 1.05 versus 2.05 in the European Region (median age: 41.7 years) and 1.65 in the American Region (median age: 30.7 years). In a \u201cworst-case\u201d scenario that did not include mitigation interventions, the median final cumulative infection incidence was 22.5 per 100 persons in the African Region (versus 69.0 in the European Region and 53.0 in the American Region) and the death rate was 0.5 per 100 persons (versus 3.9 in the European Region and 2.0 in the American Region).<\/p>\n Ayoub et al.

\n\u2022 Participants reported that following stay-at-home orders to minimize their risk of contracting COVID-19 led to both positive (e.g. drinking cessation) and negative (e.g. working out less) changes in health behaviors. Feelings of isolation, hopelessness, and worry were common. Accessing care and adhering to medical regimens was more difficult. Participants report being worried about the pandemic\u2019s effects on the economy and that their states may be re-opening too quickly.<\/p>\nHealth Inequalities in the Use of Telehealth in the United States in the Lens of COVID-19<\/h5>\n
