What is the stomach flu?
Many people use the term “stomach flu” or “24-hour flu” to describe symptoms of nausea, vomiting, or diarrhea. Although these symptoms can be related to illness caused by influenza viruses, experts at the Centers for Disease Control and Prevention suspect that many of the intestinal illnesses commonly referred to as “stomach flu” are actually caused by foodborne pathogens. Influenza or “the flu” is primarily an illness of the respiratory system caused by influenza viruses that are spread from person-to-person through coughing or sneezing. If diarrheal symptoms do not occur with respiratory symptoms, a person may actually have food poisoning.
