Early Transmission Dynamics in Wuhan, China, of Novel Coronavirus–Infected Pneumonia
TLDR
There is evidence that human-to-human transmission has occurred among close contacts since the middle of December 2019 and considerable efforts to reduce transmission will be required to control outbreaks if similar dynamics apply elsewhere.
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.
Identifying SARS-CoV-2-related coronaviruses in Malayan pangolins
TLDR
The discovery of multiple lineages of pangolin coronavirus and their similarity to SARS-CoV-2 suggests that pangolins should be considered as possible hosts in the emergence of new coronaviruses and should be removed from wet markets to prevent zoonotic transmission.
Transmission Dynamics of the Etiological Agent of SARS in Hong Kong: Impact of Public Health Interventions
TLDR
Transmission rates fell during the SARS epidemic, primarily as a result of reductions in population contact rates and improved hospital infection control, but also because of more rapid hospital attendance by symptomatic individuals.
Estimating clinical severity of COVID-19 from the transmission dynamics in Wuhan, China
TLDR
An estimation of the clinical severity of COVID-19, based on the data available so far, can help to inform the public health response during the ongoing SARS-CoV-2 pandemic.
Hand, foot, and mouth disease in China, 2008-12: an epidemiological study.
Respiratory virus shedding in exhaled breath and efficacy of face masks
TLDR
A study of 246 individuals with seasonal respiratory virus infections randomized to wear or not wear a surgical face mask showed that masks can significantly reduce detection of coronavirus and influenza virus in exhaled breath and may help interrupt virus transmission.
The Epidemiology of Severe Acute Respiratory Syndrome in the 2003 Hong Kong Epidemic: An Analysis of All 1755 Patients
TLDR
An epidemiologic analysis of the 2003 outbreak of severe acute respiratory syndrome in Hong Kong found that most cases clustered in hospitals and residential buildings, suggesting that SARS had low transmissibility, except in settings of intimate contact or clinically significant environmental contamination.
