This study aims to confirm the statistically significant decline in rotavirus related and in acute gastro-enteritis (AGE) related hospital admissions that was observed in 11 participating hospitals, after the introduction of RV vaccines in Belgium in 2006.
This retrospective study will use anonymised data, extracted from hospital databases during the period of the 1st of June 2010 until the 31st of May 2011. IMS Health sales data will be used to provide rotavirus vaccine coverage estimates (Rotarix and Rotateq) for the Belgian population during the study period. Any additional source of vaccine coverage status describing rotavirus vaccine uptake in the study population will also be reported.
Study Type
OBSERVATIONAL
Enrollment
1
Each participating centre will be requested to generate a coded list of all stool samples taken during the study period (June 1st 2010- May 31st 2011) and analysed for rotavirus, in children aged ≤5 years.
Absolute number of rotavirus related hospitalisations in children up to five years old.
Time frame: During the study period (from June 1st 2010 to May 31st 2011, i.e. up to 1 year)
Proportion of rotavirus positive tests on the total number of rota detection tests
Total number of rota detection tests and number of rotavirus positive tests of the study year will be determined by age-group of 1-year, gender, time of the event, vaccine coverage status.
Time frame: During the study period (from June 1st 2010 to May 31st 2011, i.e. up to 1 year)
The duration of rota-related hospitalisation for community acquired and nosocomial infection.
Time frame: During the study period (from June 1st 2010 to May 31st 2011, i.e. up to 1 year)
