Due to the time difference between these disease outbreaks being on the order of years, it may not be fair to make an 'apples to apples' comparison between them. These charts are meant to be as informative as possible with the data we have at our disposal, but should be viewed with an open mind as many factors may have changed over the time span of years.
Novel simply means new, the name will change.
Also known as the Wuflu, 2019-nCoV and similar.
In the same coronavirus family as SARS and MERS among others.
Median incubation period is 4.8 days.
95% of cases was between 2 to 7 days.
Asymptomatic has been proven by German researchers.
It is assumed this is not the major cause of spread, so it's not prioritized
This is how many others 1 infected person will infect.
A number lower than 1 means it will die out, higher means it will continue to spread.
2019-nCoV's latest R0 is assumed to be between 1.4 and 3.8
Note, this is a highly fluid number, and changes based on all forms of quarantine, hygiene, demographics, weather and similar. Only based on mathematical prognoses after the fact.
