Insights
Rotavirus is a significant cause of acute diarrhea in Iranian children under five. Immunization at birth may offer protection against this common childhood illness.
Area of Science:
- Pediatrics
- Virology
- Public Health
Background:
- Rotavirus infection is a leading cause of childhood morbidity and hospitalization globally.
- Acute diarrhea remains a significant health concern for infants and young children worldwide.
Purpose of the Study:
- To determine the prevalence and etiological role of rotaviruses in children with acute diarrhea in Tehran.
- To identify risk factors and seasonal patterns associated with rotavirus gastroenteritis in pediatric populations.
Main Methods:
- A monoclonal antibody-based enzyme immunoassay was used to detect rotavirus antigen in stool samples.
- Stool specimens were collected from 704 children under five with diarrhea and 176 healthy controls.
Main Results:
- Rotavirus antigen was detected in 15.3% of pediatric patients with acute diarrhea.
- Infants aged 6-12 months were most commonly affected; rotavirus infection was less frequent in breast-fed infants.
- Watery diarrhea was the predominant symptom, and detection rates peaked in spring.
Conclusions:
- Rotavirus is a major etiological agent of acute diarrhea in children under five in Iran.
- Early childhood immunization against rotavirus may be crucial for preventing symptomatic infections.
Background:
Rotavirus illness is associated with significant cause of morbidity and is a common cause of hospitalization worldwide.
Objective:
This study was performed to assess the role of rotaviruses in children presenting with acute diarrhea in two main Children's Medical Centers and one general hospital in Tehran.
Study Design:
Stool specimens from 704 children less than 5 years of age suffering from diarrhea were tested for the presence of rotaviruses by a monoclonal antibody-based enzyme immunoassay. A total of 176 fecal specimens collected from healthy children in similar age group were studied as controls.
Results:
Rotavirus antigen was detected in 15.3% of patients. Infants between 6 and 12 months of age were most frequently affected. Rotavirus infection was significantly less frequent in breast-fed than among bottle-fed babies. Watery diarrhea was present in 68.5% of children. Detection rate was highest in the spring and lowest in summer. Rotavirus can be regarded as a major etiologic agent of acute diarrhea in infants and children up to 5-years-old in Iran, immunization at birth may protect the children before their first symptomatic infection.
