Rotavirus surveillance to determine disease burden and epidemiology in Java, Indonesia, August 2001 through April...

Area of Science:

• Pediatrics
• Infectious Diseases
• Public Health

Background:

• Acute gastroenteritis is a leading cause of childhood illness and hospitalization.
• Rotavirus is a primary viral pathogen responsible for severe gastroenteritis in young children.
• Understanding the disease burden is crucial for implementing effective control strategies.

Purpose of the Study:

• To estimate the burden of rotavirus disease among children under 3 years old hospitalized with acute gastroenteritis.
• To identify the age groups and seasons most affected by rotavirus infections.
• To assess the potential impact of rotavirus vaccination on hospitalizations.

Main Methods:

• Prospective study conducted from August 2001 to April 2004 in Purworejo district and Yogyakarta city.
• Hospitalized children under 3 years presenting with acute gastroenteritis were enrolled.
• Stool samples were tested for rotavirus using laboratory methods.

Main Results:

• Out of 8929 hospitalized children, 1397 (16%) had acute gastroenteritis.
• Rotavirus was detected in 705 out of 1321 (53%) tested stool samples.
• Infections were most prevalent in children aged 7-23 months and during the dry season (June-August).
• No significant differences in socioeconomic indicators were found between rotavirus-positive and negative cases.

Conclusions:

• Rotavirus accounts for a substantial proportion of acute gastroenteritis hospitalizations in young children in the study area.
• Rotavirus vaccination represents a promising intervention to reduce childhood hospitalizations due to gastroenteritis.
• Targeted vaccination strategies may be beneficial, particularly for infants and during specific seasons.
