New virus associated with diarrhoea in neonates
Abstract:
Since December, 1974, there has been an increase in the incidence of acute diarrhoea in the neonatal nurseries of five Melbourne metropolitan hospitals. Four of these have had epidemics, and the incidence of endemic diarrhoeal disease has increased. Extracts of faeces from 148 patients from the five hospitals were examined by electron microscopy. "Duovirus" particles were detected in 82 of these extracts, including at least one from each hospital. No bacterial pathogens were isolated. It seems likely that "duovirus" is an important cause of sporadic and epidemic acute diarrhoeal disease in neonates. It is important to note that the absence of a recognized bacterial pathogen does not exclude an infective cause, especially when sugar intolerance is present. Appropriate measures to minimize the spread of infection must be employed.
Insights
A novel "duovirus" was identified as a likely cause of acute infectious diarrhea in newborns across five Melbourne hospitals. This finding is crucial for understanding and controlling neonatal diarrheal disease outbreaks.
Area of Science:
- Virology
- Neonatal Medicine
- Infectious Diseases
Background:
- An increase in acute diarrhea incidence was observed in neonatal nurseries in Melbourne starting December 1974.
- Four of the five affected hospitals experienced epidemics, alongside a rise in endemic diarrheal disease.
Purpose of the Study:
- To investigate the cause of increased acute diarrheal disease in neonates across five Melbourne metropolitan hospitals.
- To identify potential infectious agents responsible for sporadic and epidemic cases.
Main Methods:
- Faecal extracts from 148 neonatal patients were analyzed using electron microscopy.
- Samples were collected from five Melbourne metropolitan hospitals experiencing increased diarrhea incidence.
Main Results:
- "Duovirus" particles were detected in 82 out of 148 faecal extracts examined.
- The identified "duovirus" was present in samples from all five hospitals.
- No bacterial pathogens were isolated from the patient samples.
Conclusions:
- "Duovirus" is strongly implicated as a significant cause of both sporadic and epidemic acute diarrheal disease in neonates.
- The absence of a bacterial pathogen does not rule out an infectious etiology, particularly when sugar intolerance is present.
- Implementing appropriate infection control measures is essential to minimize the spread of this neonatal diarrheal disease.
