Insights
Viral infections cause most non-bacterial infantile enteritis. Rotavirus is a widespread cause of gastroenteritis in children globally, alongside other viruses like enteroviruses and adenoviruses.
Area of Science:
- Virology
- Pediatrics
- Gastroenterology
Context:
- Bacterial infections account for approximately 20% of infantile enteritis cases.
- The majority of non-bacterial infantile enteritis cases are presumed to be viral in origin.
- Research into enterotropic viruses causing infantile gastroenteritis began in 1943, with significant advancements since the mid-1950s.
Purpose:
- To review the known viral agents responsible for infantile enteritis and gastroenteritis.
- To highlight the historical discovery and evolving understanding of enteroviruses, adenoviruses, and other viral pathogens.
- To emphasize the significant role of Rotavirus as a primary cause of acute infantile gastroenteritis worldwide.
Summary:
- Enteroviruses and adenoviruses have been identified as causative agents of infantile gastroenteritis.
- The Norwalk agent, discovered in 1973, primarily affects adults but underscores the diversity of enteritis-causing viruses.
- Rotavirus has emerged as the most prevalent cause of acute infantile gastroenteritis globally, implicated in 40-60% of cases.
- More recently, Coronaviruses and Astroviruses have been detected as potential causes of gastroenteritis in animals and humans.
Impact:
- Establishes Rotavirus as a major global pathogen in pediatric gastroenteritis.
- Provides a historical overview of viral enteritis research, identifying key discoveries.
- Suggests ongoing research into emerging viral agents like Coronaviruses and Astroviruses in human and animal health.
Abstract:
About 20% of infantile enteritis are caused by bacterial infections. The most cases of non bacterial infantile enteritis are supposed to be viral infections. Arguments for the existence of enterotropic viruses arised the first time in 1943. Since the middle of the fifties, various kinds of enteroviruses are known to be causative agents of infantile gastroenteritis. The same is true occasionally for some types of adenovirus. In 1973 the Norwalk-agent was discovered provocing enteritis mainly in adults. The most important progress was achieved by the discovery of Rotavirus. The viruses of this group nowadays are ment to be the most wide spread causes of enteritis in human beings and many mammalians. Rotavirus can be found in about 40--60% of acute infantile gastroenteritis in many parts of the world. Furthermore, in the last years of Coronavirus and Astrovirus were detected as causative agents of gastroenteritis in some domestic animals and probably in human beings too.
