Vomiting and fever
Nausea and vomiting with a fever and diarrhea are common symptoms of viral stomach flu and food poisoning. These symptoms usually start to improve within 12 to 24 hours. After 48 hours, your symptoms should be mild. Diarrhea usually goes away within a week.
Fever also increases your chances of dehydration by increasing fluid loss through sweating and rapid breathing to cool the body. You may not be able to keep fluids down, or you may not feel like drinking.
A fever and changes in behaviour or a decreased level of alertness may mean a serious infection is present. Symptoms that may indicate a more serious infection include a severe stiff neck, shaking chills, or fainting. Call your doctor right away if you have these symptoms.
