Antibody Status and Incidence of SARS-CoV-2 Infection in Health Care Workers
The presence of SARS-CoV-2 anti-spike or anti-nucleocapsid IgG antibodies was associated with a reduced risk of SARS-CoV-2 reinfection over 6 months of follow-up among health care workers in the UK (n=12,541). The risk of testing positive for SARS-CoV-2 by PCR during study follow-up was 1.09 per 10,000 person-days at risk among workers who were negative…
Older Adults’ Perspectives on a COVID-19 Vaccine
In a nationally representative survey of 1,556 adults aged 50 to 80 years in the US (October 2020), 58% of older adults indicated they would be likely to get a COVID-19 vaccine, 28% said they were unlikely, and 14% were either unsure or did not know if they would get vaccinated. Interest in getting a…
Patterns of SARS-CoV-2 testing preferences in a national cohort in the United States
[pre-print; not peer-reviewed] Based on results from a discrete choice experiment (n=4,793), the uptake for testing for SARS-CoV-2 was predicted to increase by 82% to 98% if less invasive testing (saliva specimen type), dual testing (both viral and antibody tests), and at home testing scenarios were offered in addition to standard testing scenarios. Romo et…
“There’s No Place Like Home for The Holidays:” Travel and SARS-CoV-2 Test Positivity Following Thanksgiving Weekend
[pre-print; not peer-reviewed] An online panel survey administered December 4-18, 2020 to individuals from 10 US states (n = 7,905) found that many individuals reported spending Thanksgiving outside of their home (26%) or at home with at least one non-household member (27%). Planned travel over the December holidays was more common among those who tested…
Assessment of Air Contamination by SARS-CoV-2 in Hospital Settings
In a systematic review of 24 studies evaluating the level of air contamination from SARS-CoV-2 in different hospital areas and factors associated with contamination, 17% of air samples from close patient environments were positive for SARS-CoV-2 RNA, with viability of the virus found in 9% of cultures. There was no significant difference in positivity between…
Digital proximity tracing app notifications lead to faster quarantine in non-household contacts results from the Zurich SARS-CoV-2 Cohort Study
[pre-print; not peer-reviewed] Users of the SwissCovid digital contract tracing app who were notified of a non-household close contact with a SARS-CoV-2 quarantined a median of 1 day earlier than close contacts who were manually traced. Among a population-based sample of adult SARS-CoV-2 index cases (n=393) and close contacts (n=261) identified through manual contact tracing…

Changes in Elder Abuse Risk Factors Reported by Caregivers of Older Adults During the COVID‐19 Pandemic
During the COVID-19 pandemic, the caregivers of elders report experiencing adverse experiences previously established as risk factors for elder abuse. Persons responsible for the care of community-dwelling adults over the age of 60 report increasing financial hardship, greater worry about finances, heavier use of alcohol, increasing feelings of social isolation and loneliness, and greater physical,…
Comparison of Knowledge and Information-Seeking Behavior After General COVID-19 Public Health Messages and Messages Tailored for Black and Latinx Communities
In a randomized trial, participants who identified as Black and Latinx who were assigned to watch public health video messages recorded by a physician of the same race/ethnicity were less likely have knowledge gaps regarding COVID-19 when compared to those who were received messages delivered by race-discordant physicians. Participants were presented videos regarding the symptoms,…
Clinical Outcomes, Costs, and Cost-Effectiveness of Strategies for Adults Experiencing Sheltered Homelessness During the COVID-19 Pandemic
In a modeling study that simulated adults living in shelters, daily symptom screening with PCR testing of individuals who had positive symptom screening and use of alternative care sites for COVID-19 management were associated with substantially reduced new cases and costs compared with other strategies. When community transmission surges, adding universal testing every two weeks…
Changes in UK Hospital Mortality in the First Wave of COVID-19 the ISARIC WHO Clinical Characterisation Protocol Prospective Multicentre Observational Cohort Study
[pre-print; not peer-reviewed] Among people recently admitted to the hospital with COVID-19 in the United Kingdom, there was a 19% reduction in the odds of mortality compared to the first wave of the epidemic. After adjusting for demographics, comorbidities, and illness severity, the authors compared the mortality observed during a four-week interval in March to…
