Medical writers
Viral gastroenteritis (norovirus, rotavirus) is the leading cause. Bacterial forms (Salmonella, Campylobacter) follow contaminated food.
Warning signs
Bloody stools, high fever, dehydration, confusion, or symptoms lasting > 5 days require medical review.
Rehydration
Oral rehydration salts remain the cornerstone; sugary sodas worsen diarrhea.
Antibiotics are rarely useful and can prolong carriage of some pathogens.
