A “stomach bug” refers to a viral infection that affects the digestive system, commonly called viral gastroenteritis. This infection is often caused by viruses like norovirus or rotavirus. The bug typically spreads through contaminated food, water, or close contact with an infected person, making it highly contagious. It can be fueled by poor hygiene, improper food handling, and exposure to contaminated surfaces.

When experiencing a stomach bug, common symptoms include nausea, vomiting, diarrhea, stomach cramps, and sometimes fever. The infection generally resolves on its own after a few days, but you can take certain steps to feel better, including:

1. Hydration: Drink plenty of fluids like water or electrolyte solutions to avoid dehydration.
2. Rest: Allow your body to recover by getting adequate rest.
3. Light diet: Consume easily digestible foods like bananas, rice, applesauce, and toast (the BRAT diet) once you can eat.
4. Hygiene: Wash your hands frequently to prevent the spread of the virus.

As for sharp pains, yes, a stomach bug can cause intense or sharp abdominal pain, typically due to the inflammation of the stomach lining or the intestines. The severity of the pain can vary from mild discomfort to more intense cramps. However, if the pain becomes severe, prolonged, or is accompanied by blood in the stool or vomiting, you should seek medical attention, as this could indicate a more serious condition.
