Gastroenteritis, commonly known as stomach flu, is an inflammation of the stomach and intestines that results in symptoms such as nausea, vomiting, diarrhea and abdominal pain. This condition is primarily caused by viral infections, with norovirus and rotavirus being the most common culprits. Bacterial infections, including those caused by Salmonella and E. coli, as well as parasitic infections, also lead to gastroenteritis. The disease spreads through contaminated food and water, direct contact with infected individuals. According to global data, gastroenteritis affects approximately 2 billion people each year, resulting in about 1.3 million deaths, particularly among children in developing countries.

Preventing gastroenteritis involves several key practices. Regular handwashing with soap is crucial, especially before meals and after using the restroom. Ensuring food safety by cooking food thoroughly and drinking clean water also reduce the risk of infection. Additionally, vaccination against rotavirus is recommended for infants to help prevent severe cases of gastroenteritis.

Treatment primarily focuses on rehydration, as the loss of fluids from vomiting and diarrhea may lead to dehydration. Oral rehydration solutions (ORS) are effective in replenishing lost fluids and electrolytes. In severe cases, intravenous fluids may be necessary. Most individuals recover without specific medical treatment, however, it is essential to monitor for signs of dehydration, especially in young children and the elderly.

In summary, gastroenteritis is a widespread condition that have serious health implications, particularly for vulnerable populations. Understanding its causes, transmission and preventive measures is vital for reducing its impact. By practicing good hygiene and ensuring food safety, individuals may lower their risk of contracting this illness.
