Acute infectious gastroenteritis is one of the most common illnesses in humans resulting in a substantial burden to public health worldwide. Severe disease leading to hospitalizations, increased morbidity, and even death is observed among infants, children, elderly, and immunocompromised persons. Viruses are the predominant cause of gastroenteritis and include rotaviruses, noroviruses, sapoviruses, astroviruses, and adenovirus types 40 and 41. Laboratory testing is required for a reliable diagnosis of viral gastroenteritis, since the specific etiology of disease can be difficult to distinguish on the basis of clinical features alone. Recent advances in technology have resulted in the development of newer diagnostic assays that offer great promise for accurate detection of gastrointestinal viral infections. This chapter emphasizes the fundamental characteristics and clinical importance of viruses that cause gastroenteritis and highlights the laboratory methods that can be used to make a rapid and definitive diagnosis for the greatest impact on the care and management of ill patients and the prevention and control of hospital-acquired infections and community outbreaks due to enteric viruses.
