Sudden onset vomiting, lasting from 4 to 14 hours, accompanied or followed by diarrhea. Intense, debilitating, painful stomach cramping. Exhaustion. Skin looks pale or grey. Followed by 2-4 days of continued nausea, lack of appetite. Children (under 10 yrs) had fever; youngest child, 6 yrs) spiked at 103F. Observed and documented in my own 4 children over the last 2 weeks; 3 neighborhood children had similar symptoms.
