Rotavirus-associated gastroenteritis in black infants in South Africa
Insights
Rotavirus gastroenteritis is common in black infants in South Africa, affecting 23.1% of those studied. Illness peaked in autumn, with age and vomiting also being significant factors.
Area of Science:
- Virology
- Pediatrics
- Epidemiology
Background:
- Gastroenteritis is a significant cause of illness in infants worldwide.
- Rotavirus is a primary pathogen responsible for severe gastroenteritis in young children.
- Limited data existed on rotavirus prevalence in black infants in South Africa during the study period.
Purpose of the Study:
- To determine the prevalence of rotavirus-associated gastroenteritis in black infants admitted to Ga-Rankuwa Hospital.
- To identify seasonal patterns and associated risk factors for rotavirus illness in this population.
Main Methods:
- Rectal swabs were collected from black infants admitted to a gastroenteritis unit between March 1983 and February 1985.
- Samples were tested for the presence of rotavirus.
- Data on patient age, symptoms (vomiting), and illness duration were recorded.
Main Results:
- A total of 23.1% of the infants tested positive for rotavirus.
- A distinct seasonal pattern was observed, with a peak in positive cases during the autumn months.
- Infant age, the presence of vomiting, and the duration of illness were identified as important associated factors.
Conclusions:
- Rotavirus is a prevalent cause of gastroenteritis in black infants in the studied South African population.
- The findings highlight a significant seasonal trend for rotavirus infections, particularly during autumn.
- Age, vomiting, and illness duration are key factors to consider in the management of rotavirus gastroenteritis in infants.
Abstract:
From March 1983 to February 1985, rectal swabs were collected from the black infants admitted to the gastroenteritis unit at Ga-Rankuwa Hospital, Pretoria, Republic of South Africa, to investigate the prevalence of rotavirus-associated gastroenteritis. Overall, 23.1% of the patients tested were found to be positive for rotaviral illness; a definite seasonal pattern emerged, showing a marked increase in the number positive during the autumn. Other factors of importance in terms of rotaviral illness included the age distribution of the patients, the presence of vomiting, and duration of illness.
