    • rotavirus gastroenteritis
    • rotavirus gastroenteritis by the G and P types
    • severe gastroenteritis
    • severe rotavirus gastroenteritis
    • severity score of all episodes of gastroenteritis

    Rates of hospitalization in the above categories

    Proportion requiring rehydration therapy in all the above categories

  • Duration of rotavirus shedding [ Time Frame: 1 year ]
    To ascertain the duration of rotavirus shedding after an episode of rotavirus gastroenteritis

  • Rotavirus genotypes [ Time Frame: 1 year ]
    To identify genotypes of rotavirus

  • Data collection for planning and implementation of phase III trials [ Time Frame: 1 year ]
    To collect information on data essential for planning and implementation of phase III trials pertaining to trial logistics, data collection tools and validity of questions including those in the Vesikari score.

Cohort 1
Cohort 1: Infants enrolled at ≤1 week and followed up weekly till one year of age.
Cohort 2
Cohort 2: Infants enrolled at 12 months and followed up weekly till they are aged 24 months.

Detailed Description:

Field workers conducted weekly surveillance in areas allocated to them and identified pregnant women, newborns and infants aged 9 to 12 months. Children who were eligible for participation through criteria for inclusion and exclusion in the trial were enrolled. Two cohorts were recruited, one cohort enrolled within one week of birth and followed up weekly till 1 year of age (cohort 1=100) and the second cohort enrolled at 12 months of age and followed up till 24 months of age (cohort 2=100).

Weekly contact were made by field workers for both the cohorts. At each contact cases of gastroenteritis were identified. All infants with gastroenteritis were assessed by a field worker/clinical coordinator. The child was assessed for presence of dehydration, danger signs. The field worker/clinical coordinator ensured that at least one diarrheal stool specimen was collected for each episode of gastroenteritis. Infants were treated at the study clinic or escorted to one of the identified hospitals, if required.

Caregivers of the enrolled infants were explained the signs and symptoms of suspected intussusception, dehydration and danger signs that require hospital referral and were given the option to seek care from the study clinic or from one of the identified hospitals in the vicinity.

Stool specimens were collected in all diarrheal episodes. In a subset of 30 children who were identified early in a diarrheal episode and who shed rotavirus, multiple stool specimens were collected in order to assess duration of shedding of rotavirus during a natural infection.

The study was also designed to collect information on data essential for planning and implementation of phase III trials pertaining to trial logistics, data collection tools and validity of questions including those in the Vesikari score.
