Just to let you guys know... My 7yr old daughter and 11yr old both caught the Swine Flu 2 weeks ago.. it lasted pretty much (The Symptoms aching, fever,vomiting...) 3 days after that they both felt good no more fever..... Both were Tested for it after having a 103 temp and were prescribed Tamiflu. My brothers 5yr just got over it a few days ago... Pretty much is like the regular flu.. just worse on the people with medical problems and week immune systems..
