Acute gastroenteritis is one of the most common diseases affecting children and rotavirus is the major etiological agent worldwide. Although the role of rotavirus as a causal agent of gastroenteritis has been previously established in Thailand, little is known about the epidemiology of Norwalk-like viruses. The present study was designed to determine the epidemiology and clinical manifestation of Norwalk-like viruses in comparison with rotavirus in Thailand. One hundred and one children with watery diarrhea between November 2002 and October 2003 were recruited into the study. The clinical data and stool specimens were collected for clinical analysis and rotavirus and Norwalk-like virus detection. Rotavirus and Norwalk-like viruses were detected viral agent by RT-PCR method. Of 101 stool samples obtained, rotavirus was detected in 25/101 (24.7%). Norwalk-like viruses were detected in 23/101 (22.7%). Dual infections were detected in 6/101 (5.9%). Rotavirus and Norwalk-like viruses peaked in the winter time. Clinical manifestations of rotavirus and Norwalk-like viruses were watery stool, nausea, vomiting, abdominal pain and fever Norwalk-like viruses and rotavirus were the most common etiologic agents in children with acute gastroenteritis in Thailand Epidemiology and clinical manifestations of rotavirus and Norwalk-like viruses were not different.

Acute gastroenteritis is a common infectious disease syndrome, causing a combination of nausea, vomiting, diarrhea, and abdominal pain. There are more than 350 million cases of acute gastroenteritis in the United States annually and 48 million of these cases are caused by foodborne bacteria. Traveler's diarrhea affects more than half of people traveling from developed countries to developing countries. In adult and pediatric patients, the prevalence of Clostridium difficile is increasing. Contact precautions, public health education, and prudent use of antibiotics are necessary goals in decreasing the prevalence of Clostridium difficle. Preventing dehydration or providing appropriate rehydration is the primary supportive treatment of acute gastroenteritis.

Acute gastroenteritis is defined as a diarrheal disease of rapid onset, with or without nausea, vomiting, fever, or abdominal pain. In the United States, acute gastroenteritis accounts for 1.5 million office visits, 200,000 hospitalizations, and 300 deaths in children each year. Evaluation of a child with acute gastroenteritis should include a recent history of fluid intake and output. Significant dehydration is unlikely if parents report no decrease in oral intake or urine output and no vomiting. The physical examination is the best way to evaluate hydration status. The four-item Clinical Dehydration Scale can be used to determine severity of dehydration based on physical examination findings. In children with mild illness, stool microbiological tests are not routinely needed when viral gastroenteritis is the likely diagnosis. Mild gastroenteritis in children can be managed at home. Oral rehydration therapy, such as providing half-strength apple juice followed by the child's preferred liquids, is the mainstay of treatment for mild dehydration and is as effective as intravenous rehydration for preventing hospitalization and return to the emergency department. Oral rehydration solutions are recommended for moderate dehydration. Ondansetron may be prescribed if needed to prevent vomiting and improve tolerance of oral rehydration solutions. Hospitalization and intravenous fluids are recommended for children who do not respond to oral rehydration therapy plus an antiemetic and patients with severe dehydration (i.e., signs of shock or more than 10% dehydration). Handwashing, breastfeeding, and rotavirus vaccination reduce the incidence of acute gastroenteritis in young children.
