How long is the incubation period for swine flu? (time from exposure to symptoms?)
Hi Daryl in NE,
I know you asked your question quite a long time ago, and you did receive the correct information from one of our community members, but I wanted to make sure to provide you with any information that might interest you.
The incubation time is 1-3 days, and the symptoms usually do come on suddenly.

Hope you are well!
Swine flu is similar enough to any flu that I believe it's the same as any flu which is 1 to 3 days.
Flus usually appear very quickly, from no sypmtoms to being sick in a very short time.
