Willingness to Receive a COVID-19 Vaccination Among Incarcerated or Detained Persons in Correctional and Detention Facilities — Four States, September–December 2020
The COVID-19 vaccination refusal rate was 45% among 5,110 surveyed residents of three prisons and 13 jails across four states during September to December 2020 (all three prisons and 10 jails in Washington State). The most common reason for vaccination refusal was distrust of health care, correctional, or government personnel or institutions (20%). 10% of…
Longitudinal Dynamics of Antibody Responses in Recovered COVID-19 Patients
SARS-CoV-2-specific IgG antibody titers gradually increased with neutralizing antibody titers while IgM titers more quickly waned in a study of the antibody response dynamics in 24 COVID-19 recovered patients followed up to 42 weeks. While IgG titers were higher among severe than among mild cases, titers did not decline significantly over time in either group….
COVID-19 Vaccine Impact on Rates of SARS-CoV-2 Cases and Post Vaccination Strain Sequences among Healthcare Workers at an Urban Academic Medical Center a Prospective Cohort Study
[Pre-print, not peer-reviewed] Among a cohort of healthcare workers (HCW) from Boston Medical Center who received the first dose of either the Pfizer-BioNTech or Moderna vaccines, the SARS-CoV-2 infection rate was 27% and 82% lower 1-14 days and >14 days after receiving the first dose, respectively, compared to surrounding community infection rates. SARS-CoV-2 infections occurred…
Association Between Risk Factors for Complications From COVID-19, Perceived Chances of Infection and Complications, and Protective Behavior in the US
US adults with more medical risk factors associated with COVID-19 adverse outcomes perceived they had a higher chance of hospitalization or death if they were infected compared to those without risk factors in a nationally representative cross-sectional study conducted from November to December 2020 (n=5,910). Respondents with 3 or more medical risk factors perceived a…
Association Between Actual and Perceived U.S. COVID-19 Policies and Preventive Behavior
Perception about the existence of state mask mandate was 91% accurate in states with a mandate but only 46% accurate in states without one, according to a nationally representative cross-sectional survey (n=1,073) conducted in July 2020. The survey also measured participants’ mask-wearing and physical distancing behaviors and found that perceived existence of a mask mandate…

Factors Associated with SARS-CoV-2 Positivity in 20 Homeless Shelters in Toronto, Canada, from April to July 2020: A Repeated Cross-Sectional Study
Among 872 residents of homeless shelters in Toronto, Canada across 20 shelter locations, 504 unique individuals had a SARS-CoV-2 tests performed in outbreak settings (April 1 to July 31, 2020), of which 69 (14%) were positive. There was no association between SARS-CoV-2 positivity and medical history or symptoms. Those who tested positive for SARS-CoV-2 were…
Role of High-Dose Exposure in Transmission Hot Zones as a Driver of SARS-CoV-2 Dynamics
A model of SARS-CoV-2 transmission found that community spread may be highly influenced by transmission within “hot zones” characterized by high viral dose exposure, such as indoor settings with poor ventilation such as long-term care facilities, prisons, and food processing plants. The authors conclude that this may indicate that targeting interventions to prevent transmission in…
Suicide Attempt and Intentional Self-Harm during the Earlier Phase of the COVID-19 Pandemic in Washtenaw County, Michigan
During the first 12 weeks of the COVID-19 pandemic in Washtenaw County, Michigan (on or after March 10, 2020), there were 40% fewer emergency department encounters than expected for suicide attempt and intentional self-harm compared to prior years. The study analyzed data from more than 3,000 individuals receiving emergency department care for suicide-related behavior from…
Expansion of a Direct-to-Patient Telemedicine Abortion Service in the United States and Experience during the COVID-19 Pandemic
A direct-to-patient telemedicine abortion service was found to be safe, effective, and acceptable according to a study in which participants were mailed mifepristone and misoprostol and received counselling and screening remotely. 1,390 packages were mailed between May 2016 and September 2020 and enrollment increased substantially with the onset of COVID-19. Although participants were required to…
COVID-19 Case and Mortality Rates in the Federal Bureau of Prisons
A study of COVID-19 in US Federal Prisons found that both the case rate and mortality was higher among inmates in these facilities compared to the general population. The crude case rate (11,710 per 100,000 population) was 5-times higher than that in the general population and the age- and sex-adjusted mortality rate for COVID-19 (77.4…
