Virus Symptoms

Anyone know what virus this is:

headache 2 days prior to onset of other sxs
stomach ache leading quickly to violent vomiting and a spike in fever
(around 102)
severe body ache and fever for 24 hours
off and on diahrea
gradual recovery over next few days
return to baseling w/i one week

I had it this past spring and I have it again.  Not fun.
