Serial interval of novel coronavirus (COVID-19) infections.
Reads0
Chats0
TLDR
The serial interval of COVID-19 is close to or shorter than its median incubation period, indicating that a substantial proportion of secondary transmission may occur prior to illness onset and that calculations made using the SARS serial interval may introduce bias.Citations

Weather variability and transmissibility of COVID-19: a time series analysis based on effective reproductive number
Michael Nevels,Xiaohan Si,Hilary Bambrick,Yuzhou Zhang,Jian Cheng,Hannah McClymont,Michael B. Bonsall,Wenbiao Hu +7 more
TL;DR: In this article, the effects of climate factors (i.e., daily average temperature and average relative humidity) on effective reproductive number of COVID-19 outbreak in Wuhan, China during the early stage of the outbreak was assessed.

TL;DR: In this paper, the authors conducted an in-depth analysis of the response to a big flight-associated COVID-19 outbreak in Vietnam in March 2020 that involved contact tracing, systematic testing and strict quarantine up to third generation contacts.

TL;DR: A large number of cases of encephalitis are associated with central nervous system injuries, particularly among nurses, which is a sign of neglect in the early stages of the disease.

Covid-19 and net foreign exchange reserve relationship in turkey: evidence from ardl bounds testing approach
TL;DR: In this paper, the authors investigated whether there's a correlation between Covid-19 and the net foreign exchange reserve, which shows sensitivity to crises, and found that the change in reserves escalated the pandemic.

Transmission of SARS-CoV-2 before and after symptom onset: impact of nonpharmaceutical interventions in China
TL;DR: It is suggested that interventions which limit opportunities for transmission in the later stages of infection, such as contact tracing and isolation, may have been particularly effective at reducing transmission of SARS-CoV-2.

TL;DR: 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.

TL;DR: It is estimated that a single infectious case of SARS will infect about three secondary cases in a population that has not yet instituted control measures, and public-health efforts to reduce transmission are expected to have a substantial impact on reducing the size of the epidemic.

TL;DR: The incubation period falls within the range of 2–14 days with 95% confidence and has a mean of around 5 days when approximated using the best-fit lognormal distribution and it is recommended that the length of quarantine should be at least 14 days.
Journal ArticleDOI
Factors that make an infectious disease outbreak controllable.
TL;DR: It is concluded that severe acute respiratory syndrome and smallpox are easier to control using these simple public health measures and should be a priority during an outbreak of a novel infectious agent.
