What is the most common treatment for acute gastroenteritis caused by viral infections?

The most common treatment for acute gastroenteritis caused by viral infections is fluid replacement. This condition often leads to dehydration due to symptoms like vomiting and diarrhea, which result in the loss of fluids and electrolytes. The primary goal of treatment in cases of viral gastroenteritis is to maintain hydration and restore the balance of electrolytes.

Oral rehydration solutions are typically recommended, especially for mild to moderate dehydration, as they contain the right balance of water, salts, and sugars to effectively rehydrate the body. In more severe cases, intravenous fluid replacement may be necessary to ensure adequate hydration and electrolyte levels.

Antibiotics are ineffective against viral infections and are therefore not used in this context. Antiviral medications target specific viral infections and are not the standard treatment for the majority of cases of viral gastroenteritis. Aspirin is not indicated for treating gastroenteritis and is generally avoided in children due to its association with Reye's syndrome, a serious condition. Thus, fluid replacement stands out as the most relevant and effective treatment approach for viral gastroenteritis.
