Burden of rotavirus disease and cost-effectiveness of universal vaccination in the Province of Genoa (Northern Italy)

摘要

Rotavirus is acknowledged to be a major cause of acute gastroenteritis in infants and young children. As gastroenteritis due to rotavirus is a public health problem and two new vaccines are currently available, we investigated the rotavirus burden and developed a cost-effectiveness analysis, using data collected in the Province of Genoa (Italy), to evaluate the benefits of new borns vaccination. The cost-effectiveness of a rotavirus vaccination programme in the Province of Genoa was performed, in comparison with no vaccination, for both the regional healthcare system (RHS) and society (S). In 2006, admissions to the paediatric emergency department for gastroenteritis numbered 2338 (about 11% of total admissions); of these 33% were hospitalised. In 28% of cases, the children tested positive for rotavirus. During epidemics, paediatricians receive from 3 to 5 calls per day for gastroenteritis, carry out 1 or 2 ambulatory examinations and for children with a severe case history, make house visits. A rotavirus immunisation programme would have a great impact on disease burden, in that 90% coverage would reduce the number of severe cases by more than 85%. From the perspective of both the RHS and S, vaccination proved to be highly cost-effective.
