We study transmission of COVID-19 using five well-documented case studies : a Washington state church choir, a Korean call center, a Korean exercise class, and two different Chinese bus trips. In all cases the likely index patients were pre-symptomatic or mildly symptomatic, which is when infective patients are most likely to interact with large groups of people. An estimate of N 0 , the characteristic number of COVID-19 virions needed to induce infection in each case, is found using a simple… 
Characterizing superspreading of SARS-CoV-2 : from mechanism to measurement
TLDR
It is found that highly heterogeneous contact behavior is required to produce the extreme superspreading estimated from recent COVID-19 out-breaks, and estimates are noisy and subject to biases in data collection and public health capacity, potentially leading to an overestimation ofsuperspreading.
SARS-CoV-2 Aerosol Transmission Indoors: A Closer Look at Viral Load, Infectivity, the Effectiveness of Preventive Measures and a Simple Approach for Practical Recommendations
TLDR
A dose–response model was adopted to analyze 25 documented outbreaks at infection rates of 4–100%.
SARS-CoV-2 Aerosol Transmission Indoors: A Closer Look at Viral Load, Infectivity, the Effectiveness of Preventive Measures and a Simple Approach for Practical Recommendations
TLDR
A layered approach of different measures is recommended to mutually compensate for possible failures of any one measure, to increase the degree of protection and thus reduce the risk of transmission of SARS-CoV-2.
The airborne contagiousness of respiratory viruses: A comparative analysis and implications for mitigation
TLDR
In congregate settings, current ventilation standards are unlikely to control the spread of viruses with upper quartile ERq values above 10 quanta h–1, such as SARS-CoV-2, indicating the need for additional control measures.
Genomic epidemiology of superspreading events in Austria reveals mutational dynamics and transmission properties of SARS-CoV-2
TLDR
This study provides a national-scale analysis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) superspreading during the first wave of infections in Austria, a country that played a major role in initial virus transmissions in Europe.
Outdoor Airborne Transmission of Coronavirus Among Apartments in High-Density Cities
TLDR
A first-principles model, airborne transmission via outdoor route (ATOR), was developed to simulate airborne pathogen generation, natural decay, outdoor dispersion, apartment entry, and inhalation exposure of susceptible persons in neighboring apartments and suggested that the predicted viral exposure was positively correlated with the probability of disease infection at apartment level for both events.
Catch Me (If You Can): Assessing the Risk of SARS-CoV-2 Transmission Via Euro Cash
In the light of fears that the SARS-CoV-2 virus might be transmitted via cash – fears that were stoked by statements in the media and from public authorities – this paper aims to address the
Response to comment on “Genomic epidemiology of superspreading events in Austria reveals mutational dynamics and transmission properties of SARS-CoV-2”
TLDR
Analysis of SARS-CoV-2 genome sequencing data identifies several highly recurrent genetic variants with low allele frequencies, which, if filtered out, provide estimates consistent with tighter transmission bottlenecks.
Patterns of within-host genetic diversity in SARS-CoV-2
TLDR
While sharing of within-host variants between samples could help the reconstruction of transmission chains, mutational hotspots and rare cases of superinfection can confound these analyses, it is found that within- and between-host diversity show strong purifying selection, particularly against nonsense mutations.

TLDR
Cases linked to superspreading events are estimated to account for 80% of all local transmission of SARS-CoV-2 in Hong Kong in a study with implications for public health policies.
Characterizing superspreading events and age-specific infectiousness of SARS-CoV-2 transmission in Georgia, USA
TLDR
An individual-level spatiotemporal mechanistic framework is formulated to integrate individual surveillance data with geolocation data and aggregate mobility data, enabling a more granular understanding of the transmission dynamics of SARS-CoV-2.
Temporal dynamics in viral shedding and transmissibility of COVID-19
TLDR
It is estimated that 44% (95% confidence interval, 25–69%) of secondary cases were infected during the index cases’ presymptomatic stage, in settings with substantial household clustering, active case finding and quarantine outside the home.
Transmission of SARS-CoV-2 by inhalation of respiratory aerosol in the Skagit Valley Chorale superspreading event
TLDR
It is demonstrated that the risk of infection is modulated by ventilation conditions, occupant density, and duration of shared presence with an infectious individual, and how the risk would vary with several influential factors.
Transmission of SARS‐CoV‐2 by inhalation of respiratory aerosol in the Skagit Valley Chorale superspreading event
TLDR
It is explored how the risk of infection would vary with several influential factors: ventilation rate, duration of event, and deposition onto surfaces, to better understand the factors that promote superspreading events.
Quantifying SARS-CoV-2 transmission suggests epidemic control with digital contact tracing
TLDR
A mathematical model for infectiousness was developed to estimate the basic reproductive number R0 and to quantify the contribution of different transmission routes and the requirements for successful contact tracing, and the combination of two key parameters needed to reduce R0 to less than 1 was determined.

SARS-CoV-2 is difficult to contain because most transmissions occur during the pre-symptomatic phase of infection. Moreover, in contrast to influenza, while most SARS-CoV-2 infected people do not
Community Outbreak Investigation of SARS-CoV-2 Transmission Among Bus Riders in Eastern China.
TLDR
Individuals who rode a bus to a worship event with a patient with COVID-19 had a higher risk of SARS-CoV-2 infection than individuals who rode another bus to the same event, suggesting airborne spread of the virus seems likely to have contributed to the high attack rate in the exposed bus.
High SARS-CoV-2 Attack Rate Following Exposure at a Choir Practice - Skagit County, Washington, March 2020.
TLDR
Data demonstrate the high transmissibility of SARS-CoV-2 and the possibility of superemitters contributing to broad transmission in certain unique activities and circumstances and recommend that persons avoid face-to-face contact with others, not gather in groups, avoid crowded places, maintain physical distancing of at least 6 feet to reduce transmission, and wear cloth face coverings in public settings where other social distancing measures are difficult to maintain.

TLDR
Air and surface samples collected during the initial isolation of 13 individuals confirmed positive with COVID-19 infection showed evidence of viral contamination, indicating that SARS-CoV-2 is shed to the environment as expired particles, during toileting, and through contact with fomites.
