Modeling Transmission Dynamics and Effectiveness of Worker Screening Programs for SARS-CoV-2 in Pork Processing Plant
[Pre-print, not peer-reviewed] A modeling study of SARS-CoV-2 transmission and screening programs in pork processing facilities during spring 2020 found that the effectiveness of routine PCR-screening at minimizing disease spread was influenced more by testing frequency than delays in results, the initial reproduction number, or background community transmission rates. While testing every three days prevented ~25-…

SARS-CoV-2 Transmission in Intercollegiate Athletics Not Fully Mitigated with Daily Antigen Testing
[Pre-print, not peer-reviewed] Two SARS-CoV-2 outbreaks occurred among US university athletic programs during the fall 2020 despite mandatory directly observed daily antigen testing, suggesting that antigen testing alone may not be sufficient to prevent outbreaks in congregate settings. In the first outbreak, 32 confirmed cases occurred within an athletics program after the index patient attended…

Nursing Facilities, Food Manufacturing Plants and COVID-19 Cases and Deaths
A higher number of meatpacking plants and bakeries within a hospital reference region (HRR) or a metropolitan statistical area (MSA) was associated with a higher number of COVID-19 related deaths in the US through May 2020. After adjusting for demographics and socioeconomic characteristics, an additional plant within an HRR and MSA was associated with 21%…

Risk Factors Associated With COVID-19 Transmission Among US Air Force Trainees in a Congregant Setting
A higher number of symptoms and higher viral loads were associated with subsequent clusters of SARS-CoV-2 cases among cohorts of US Air Force basic trainees. Among 10,613 US Air Force basic trainees, of whom 3% (403) received a diagnosis of COVID-19 during the study period, higher numbers of symptoms and higher viral loads (lower cycle…

Occupational Exposures and Mitigation Strategies among Homeless Shelter Workers at Risk of COVID-19
[Pre-print, not peer-reviewed] An online survey of 106 workers at homeless shelters in 17 shelter networks in Washington, Massachusetts, Utah, Maryland and Georgia found that 15% of workers reported testing positive for SARS-CoV-2, with 80% believing they were infected at work. The survey was conducted to assess occupational exposures to SARS-CoV-2, characterize job practices, and…

Effectiveness of Non-Pharmaceutical Interventions on Child and Staff COVID-19 Cases in US Summer Camps
[Pre-print, not peer-reviewed] Mask adherence among children in US summer camps was approximately 34% according to a survey of 486 summer camps that operated in 2020. Approximately 15% of camps reported one or more confirmed COVID-19 cases in either campers or staff, with three camps reporting a COVID-19 outbreak. Among the types of non-pharmaceutical interventions…

SARS-CoV-2 Transmission among Children and Staff in Daycare Centres during a Nationwide Lockdown in France: A Cross-Sectional, Multicentre, Seroprevalence Study
Children (n=327) and staff (n=197) attending daycare centers in France during the lockdown from March to May 2020 had similar seroprevalence (4% and 7%, respectively) to a comparator group consisting of laboratory or administrative personnel not occupationally exposed to COVID-19 patients or children (5%). In addition, seropositive children were 7-times as likely to have been…

Using Non-Pharmaceutical Interventions and High Isolation of Asymptomatic Carriers to Contain the Spread of SARS-CoV-2 in Nursing Homes
[Pre-print, not peer-reviewed] A pandemic influenza model with COVID-19 parameters applied to a nursing home setting showed that the attack rate was more sensitive to identification and isolation of asymptomatic cases than implementation of non-pharmaceutical interventions (NPIs). Varying NPI levels from baseline to rigorous measures had no significant effect on attack rate in a scenario…
SARS-CoV-2 Control on a Large Urban College Campus Without Mass Testing
[Pre-print, not peer-reviewed] Testing of symptomatic students combined with a random subset of asymptomatic students at the University of Pittsburgh demonstrated a prevalence SARS-CoV-2 infection of 0.4% and a case rate of 232 per 10,000 students, comparable to the case rates of other public urban institutions that implemented mass-testing. The authors suggest that targeted testing,…

SARS-Cov-2 Prevalence Transmission Health-Related Outcomes and Control Strategies in Homeless Shelters Systematic Review and Meta-Analysis
A systematic review and meta-analysis including 13 studies (8 of which are US-based) found that the pooled baseline SARS-CoV-2 prevalence among homeless shelter is 2.1% among residents and 1.7% among staff. However, in outbreaks, the prevalence increases to 30% among residents and 15% among staff. The main infection prevention and control measures cited included universal…
