>We collected extensive individual case reports and estimated key epidemiology parameters, including the incubation period.
>Integrating these estimates and high-resolution real-time human travel and infection data with mathematical models we estimated that the number of infected individuals during early epidemic double every 2.4 days, and the R0 value is likely to be between 4.7 and 6.6.
>We further show that quarantine and contact tracing of symptomatic individuals alone may not be effective

This is way more infectious than anyone predicted and is likely everywhere now.Be prepared.
