COVID-19 Outbreak in an Amish Community — Ohio, May 2020
Social gatherings likely contributed to the rapid transmission of SARS-CoV-2 throughout an Amish community in rural Ohio. Access to testing was increased after an initial cluster of seven SARS-CoV-2 cases was identified in May, resulting in 77% positivity among the 30 additional residents tested by RT-PCR. Transmission was associated with multiple social gatherings, including church…

Multiple COVID-19 Outbreaks Linked to a Wedding Reception in Rural Maine — August 7–September 14, 2020
An outbreak investigation of a wedding reception in rural Maine attended by 55 people in August 2020 initially identified 30 primary COVID-19 cases, but infected wedding guests were later identified as the likely source of outbreaks in the local community, a long-term care facility 100 miles away, and a correctional facility 200 miles away. Overall,…
Risk Factors for Mortality of Residents in Nursing Homes with Covid-19 a Retrospective Cohort Study
[Pre-print, not peer reviewed] In a retrospective study of 167 nursing homes providing long-term care in Spain, the risk of COVID-19 related death was greater in facilities with a higher percentage of complex patients or advanced diseases, lower capacity for implementing preventive measures, and in districts with higher incidence of COVID-19. A higher population density…
Long-Distance Airborne Dispersal of SARS-CoV-2 in COVID-19 Wards
Detection of SARS-CoV-2 in the ventilation system of 3 linked COVID-19 wards in a Swedish hospital suggests long-distance airborne dispersal beyond droplet transmission. SARS-CoV-2 genetic material was detected in 7 of 19 vent openings within wards, while 8 of 9 samples obtained from HEPA exhaust filters located several floors above the wards were also positive…
ARS-CoV-2 Transmission among Marine Recruits during Quarantine
Among a cohort of US Marine Corps recruits who were tested on days 1-2, 7, and 14 after arrival to campus (n=1848), 16 (0.9%) tested positive for SARS-CoV-2 by day 2, followed by 35 more (1.9%) by day 14. Genomic analysis from 32 positive recruits identified 6 clusters among 18 recruits, providing evidence for local…
An Outbreak of Covid-19 on an Aircraft Carrier
In an outbreak on an aircraft carrier in late March 2020, 1271 (26.6%) of 4779 crew members had SARS-CoV-2 positive PCR results, and an additional 60 crew members had suspected COVID-19. In this predominantly young (mean age 27 years) population, 23 were hospitalized, 4 received intensive care, and 1 died. Nearly 80% were asymptomatic at…

The Role of Children in the Transmission Chain of SARS-CoV-2 a Systematic Review and Update of Current Evidence
[Pre-print, not peer reviewed] A systematic review and meta-analysis of 22 studies on the role of children in the SARS-CoV-2 transmission chain confirms that children are able to be infected and transmit SARS-CoV-2 in a variety of settings, with potentially different dynamics depending upon age. Transmission chains in which the index case was a child…
Modeling the Stability of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) on Skin, Currency, and Clothing
Harbourt et al. exposed SARS-CoV-2 to human skin, paper currency, and clothing in a lab setting under various temperatures and found that the virus was more stable in colder conditions. At 22oC, the virus was stable on human skin, a $1 bill, and on clothing, for at least 96 hours, 8 hours, and 4 hours,…
Characteristics and Outcomes of Neonatal SARS-CoV-2 Infection in the UK: A Prospective National Cohort Study Using Active Surveillance
A national prospective study in the UK found low incidence (5.6 per 10,000 live births) of neonatal SARS-CoV-2 infection. Of the 66 babies identified with SARS-CoV-2 during the study period, 17 (26%) babies were born to mothers with known perinatal SARS-CoV-2 infection, and only 2 (3%) were considered to have possible vertically acquired infection. The…
High Prevalence of SARS-CoV-2 Antibodies in Pets from COVID-19+ Households
In households with a SARS-CoV-2 positive case, 10 out of 47 (21%) cats and dogs were seropositive for antibodies against SARS-CoV-2, compared to 1 out of 38 (3%) cats and dogs in households without a person with known SARS-CoV-2 infection. Seroprevalence was not associated with the number of pets per household, which the authors suggest…
