A great site for basic swine flu info. http://diseases-viruses.suite101.com/topiclist/article.cfm/swine_flu_disease focuses on prevention, symptoms, and spotting an emergency.
Onset seems to be rather quick with most patients feeling fine then the symptoms hit them out of the blue although some patients state they did not feel sick prior to symptoms but they did not feel like themselves either. Most patients state onset times range from minutes to several hours with the latter being less frequent.
We have 15 pediatrics in the ICU 3 on ventilators, 4 adult deaths from H1N1, (that was the count last week) there were some underlining conditions. I wasn't going to get the shot myself, but decided to.... do to my ashma, and not wanting to spread it to my family. My wife and kids are not getting it.... Eat healthy and wash your hands!
Stay low and be safe
