"gastric flu" 的定义和意义

What is "gastric flu"?

Gastric flu, often referred to as gastroenteritis, is an illness that causes inflammation of the stomach and intestines. It is usually caused by viruses such as norovirus or rotavirus, although bacteria, parasites, or contaminated food and water can also be responsible. Symptoms typically include nausea, vomiting, diarrhea, stomach cramps, and sometimes fever. Gastric flu is highly contagious and can spread through close contact with infected individuals, contaminated surfaces, or consuming contaminated food or water. Most cases of gastric flu resolve on their own within a few days with rest, hydration, and supportive care.
