What Is the Stomach Flu?
The stomach flu, also known as viral gastroenteritis, is an inflammation of the stomach and intestines caused by various viruses, including norovirus, rotavirus, adenovirus, and astrovirus. It is highly contagious and spreads through contact with an infected person, contaminated food or water, and surfaces. The primary symptoms of the stomach flu include diarrhea, vomiting, nausea, and abdominal cramps, which typically begin one to three days after exposure to the virus. These symptoms can lead to dehydration, especially in young children, the elderly, and individuals with weakened immune systems.
In addition to gastrointestinal symptoms, patients with stomach flu may also experience fever, headache, muscle aches, and fatigue. The illness usually lasts for a few days, but in some cases, symptoms can persist for up to ten days. Treatment focuses on symptom management and preventing dehydration. This involves drinking plenty of fluids, using oral rehydration solutions, and resting. Good hygiene practices, such as frequent handwashing and disinfecting surfaces, are essential to prevent the spread of the virus. While stomach flu can be uncomfortable, most people recover fully without long-term health effects.
