Symptoms of Influenza

The stomach flu (gastroenteritis) is a nonspecific term for various inflammatory problems in the gastrointestinal (GI) tract. Gastroenteritis may be of short duration (acute viral) or for many months (chronic gastroenteritis, such as that caused by food allergies). Signs and symptoms of stomach flu depend on the cause. The most frequent signs and symptoms of viral stomach flu include: diarrhea, nausea, and vomiting. Signs and symptoms of bacterial stomach flu include fever, and bloodied diarrhea (hemorrhagic gastroenteritis). Food allergies may produce eosinophilic gastroenteritis, a sign of which is increased eosinophils (a type of white blood cell) seen in the blood. Children with the stomach flu or gastroenteritis have similar symptoms to adults, but also may have symptoms such as refusing to drink or being very thirsty. The main way contagious causes of the stomach flu are spread is person to person via the fecal-oral route. Individuals at most risk of catching the stomach flu are those in close association with an infant, child, or an adult that has a viral or bacterial cause of stomach flu . Contagious gastroenteritis is spread or transmitted usually by the fecal – oral route or by eating or drinking contaminated foods. #Influenza #genetics #VIRUS #bacteria #stomachFlu
