Infectious period of influenza
The infectious period is typically three to six days, whereas the duration of the disease is typically two to seven days.
[The summary statement comes from Earn et al (2002, TREE).  The references from there need to be stated here, and more recent references are also needed.  Particularly in the last few years there has been discussion of the distribution, rather than simply the mean, of the infectious period.  References required...]
