Part of the show Avian Flu, How Flu Spreads and How to Avoid It

Question

David from Vancouver asked:

Does the number of virus particles you have in your body affect the severity or duration of an illness?

Answer

I think that answer is that the fewer virus particles you have in your nose at one time, the longer the incubation period is likely to be. So it will be the same severity, but it will take longer to get to that point.
