Final answer:
Gastroenteritis is the condition involving inflammation of both the stomach and intestinal linings caused by infections that can lead to symptoms like vomiting, diarrhea, and fever.
Step-by-step explanation:
An inflammation of the intestinal lining commonly caused by infection is known as gastroenteritis. This condition involves inflammation of both the stomach lining and the intestinal lining, producing symptoms like nausea, vomiting, diarrhea, aches, and fever. Enteritis is a more specific term referring to inflammation of the intestinal mucosa. When caused by an infection, organisms or their toxins inflame the gastrointestinal tract lining, potentially resulting in dehydration due to severe vomiting and diarrhea. In the case of bacterial infections, such as with Shigella, symptoms can include stomach cramps, fever, and watery diarrhea, sometimes containing pus, mucus, and blood, leading to more severe complications like ulceration of the mucosa, dehydration, and rectal bleeding.
