TLDR
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.Abstract:
Severe acute respiratory syndrome (SARS) is a recently described illness of humans that has spread widely over the past 6 months. With the use of detailed epidemiologic data from Singapore and epidemic curves from other settings, we estimated the reproductive number for SARS in the absence of interventions and in the presence of control efforts. We estimate that a single infectious case of SARS will infect about three secondary cases in a population that has not yet instituted control measures. Public-health efforts to reduce transmission are expected to have a substantial impact on reducing the size of the epidemic.read more

Understanding the spatial diffusion process of severe acute respiratory syndrome in Beijing
TL;DR: It is revealed that doctors were important in the spread of SARS in Beijing, and hospitals were not as important as doctors in the contagion period, but the population density was more significant than the population size, although they were both important throughout the whole period.

TL;DR: The results indicated the transmission of COVID-9 occurs among close contacts during the incubation period, which may lead to a quarantine loophole and strong and effective countermeasures should be implemented to prevent or mitigate asymptomatic transmission during the hatched period in populations at high risk.

TL;DR: A novel coronavirus is associated with this outbreak of severe acute respiratory syndrome, and the evidence indicates that this virus has an etiologic role in SARS.

Seasonal variation in host susceptibility and cycles of certain infectious diseases.
TL;DR: Ample evidence indicates that photoperiod-driven physiologic changes are typical in mammalian species, including some in humans, and underlie human resistance to infectious diseases for large portions of the year and the changes can be identified and modified, the therapeutic and preventive implications may be considerable.
