Even though stomach flu or acute gastroenteritis is commonly benign and self-limited and subsides within a few days; it can knock you out for a few days and leave you extremely tired and weak. With your intestines attacked by the flu, one often manifests symptoms like nausea, vomiting, diarrhoea and even mild fever.
All raw food must be washed well before eating or cooking. If someone had contracted the infection, he/she should not cook or serve food to others for at least three to four days after the symptom has cleared. Finally, remember to quarantine the sick person to prevent spread or reoccurrence.
